Phoenix Contact – Your Partner in Safety and Reliability for Railway Industry

From |

RailwayPhoenix Contact has been serving the railway industry for decades, especially for rolling stock and signalling. Safety and reliability has always been our number one concern when developing products for railway applications.

Safety on Board

The basic requirement for safety and reliability is standard compliance. Phoenix Contact has been certified by the International Railway Industry Standard (IRIS) since April 2008 and this standard is based on the quality management standard DIN EN ISO 9001, which has been extended with international railway-specific requirements. The ongoing tests during the development and production cycle of the products are essential to guarantee the product quality.

On top of that, all rail-specific products from Phoenix Contact fulfill the standards of DIN EN 50155, an international standard covering rolling stock; DIN EN 50121 electromagnetic compatibility; and EN 45545, fire protection on rail vehicle. Besides, shock and vibration test, material test and other fire protection is also critical for the railway application.

Safety should not be limited to the big ticket items and should even be extended to the passive component level. For example, the cable markings like shrink sleeve should be halogen-free and fulfill DIN 5510-2 with an oxygen index of 34.9%. besides being halogen-free, the cable ducts should enable individual bars to be broken without using any tools or resulting in any burr through defined breaking points according to EN 45545-2 (R22/R23:HL3). Behaviour in fire is another key concern and the plastic used for Phoenix Contact’s terminal blocks is halogen-free polyamide PA 6.6; which meets the highest safety requirement of UL 94 V0.

Network on Board

Nowadays, commuters demand for “Internet on board” has made the information and infotainment systems essential in trains. The M12 network connectors with a mechanically robust design, in compliance with IEC 61076-2-101, together with high quality cables meeting the requirement of EN 45545-2 will ensure reliable communications. The heavy-duty connector, compliant with IEC 61373, with modular contact inserts form a flexible and safe transmission of signal and power circuit on rolling stock carriage connection and simultaneously ensures comprehensive protection in the event of electromagnetic interference fields.

Surge Protection

Surge voltages and lightning strikes are common issues in signalling, hence the surge protective device (SPD) become significantly important to maintain reliable signal transmission. Phoenix Contact’s SPD has been tested according to IEC 61643-21 and the plug can be disconnected for test and maintenance by using the portable test laboratory. According to IEC 62305-3, the SPD must be tested regularly and the test values should be documented and traceable. Additional features like multi-stage monitoring (green – operating, red – fail and yellow – reach performance limit) for predictive maintenance and remote signalling for early detection of overloaded SPD can help to further enhance reliability.

Power Supply

The power supply unit (PSU) is used to convert main AC to low-voltage regulated DC power and it should at least be compliant with EMC Directive 2014/30/EU, IEC 60950-1, DIN EN 61558-2-16 and UL 508. To ensure smooth operation and maximum uptime, the redundancy setup of the power supply cannot be overlooked.

A redundant system can made up of two power supplies and a diode or Phoenix Contact’s O-RING to prevent back flow of current. An ORING being a more advanced and modern redundancy module compared to the diode, comes with auto-current balancing (ACB) technology which ensures the power supplies work equally hard. This enables the power supplies to have a longer and more consistent lifespan.

The redundancy status as well as the status of the ORING can be monitored, whereas this cannot be done with a DIODE. The PSU becomes more reliable and dependable when it is capable of sending analogue signals to control system on measurement values such as real time current, voltage and power for early detection of operational fault as well as critical information to the user.

Quint Power – 4G Power Supply with NFC

From |

QUINT Power - 4G Power supplyHave you heard of Phoenix Contact’s QUINT POWER range of power supplies?

If you have not, where were you!

Our QUINT power supplies have been consistently making waves as THE power supply fit for any industrial use.

It is that good that Phoenix Contact has released the fourth generation of the high-performance QUINT POWER range, only this time it’s spearheading the industry by embracing the spirit of IIOT.

Tell us MORE about this QUINT

Our QUINT POWER is the one and only power supply in the market to incorporate Near Field Communication (NFC) technology.

This feature is the latest addition to the already proven power supply unit that comes with SFB (Selective Fuse Breaking) technology, preventive function monitoring, high noise immunity as well as Power Boost.

Wait, What’s Power Boost?

QUINT 4 Power Supplies dynamic boost

The Power Boost technology allows the power supply unit to withstand indefinitely 125% or tolerate up to 200% of its maximum rated output current for 5 seconds without malfunctioning.

You heard that right, up to 200% of its maximum output current unlike others who would be fried to a crisp right about now.

Not just a Power Boost but empowering People too!

This technology allows users; engineers or technicians, to read and download configuration data of the power supply with any NFC enabled devices such as smartphones or tablets.

All you need is an Android device and you’re good to go.

This will also be handy at industrial sites during commissioning or maintenance where more often than not, there will be unforeseen circumstances where configuration cables are misplaced or worse laptops are not downloaded with the configuration software.

Another practical advantage is that the NFC technology allows configuration to be done in places that have low accessibility.

Examples are hard to reach places such power supply units that are installed at tight, very high or very low positions where it is difficult to carry a laptop.

Laptops can be bulky and requires a power supply to read power supplies (oh the irony). With smartphones and NFC, you could read data through the palms of your hands.

The QUINT POWER configuration App can be downloaded for free from the Google Play Store.

Say goodbye to legacy multi-meters and expensive devices!  Who says you can’t use your phones on the job.

I’m super excited now! Tell me more…..

Configuration data such as device details, output voltage, output characteristics, signalling and control input mode can now be read, configured and then be downloaded without any need for physical cabling to the power supply.

Surely with the QUINT you’ll be seeing increase in productivity.

Without the access baggage -laptop and configuration cable – it reduces the time needed for configuration especially for projects with large quantities of power supply units.

The QUINT POWER power supply range can be used in various industries such as oil and gas, transportation, water, marine, power and chemical facilities as well as in the factory automation and manufacturing facilities where reliability and technical superiority are highly valued.

So if you’re looking for POWER SUPPLIES, look no further.

Our QUINT 4 is your answer.

With NFC enabled you’ll be giving your business the power of electricity, in your hands.

Let there be light: Phoenix Contact Components for Reliable Power Grids

On 7 July 2017, Phoenix Contact Singapore Team organised a’ Dining in the Dark’ event as part of Corporate Social Responsibility.  In the short 2 hours without our sight, we experienced a range of emotions such as fear and helplessness. This event also allowed us to understand the challenges that persons with visual impairment faced daily. It is truly a meaningful event that we are thankful to be able to experience with the friends we made from work.

Phoenix Contact's 'Dining in the Dark' CSR Event

Phoenix Contact’s ‘Dining in the Dark’ CSR Event

In today’s world, it might not be an exaggeration to say that we will feel the fear and helplessness if we do not have access to electricity. For a start, life-sustaining equipment in hospitals will not be in operation. Many of life’s conveniences such as lights, entertainment, air-conditioning etc. will be stripped from us. For this, electrical grids are always considered critical infrastructure all around the world and efforts are made to ensure the grid is always operating. Phoenix Contact contributes to this reliability with our products. Below are some examples:

A Simple Tip to Help Ensure Your Power Supply Is Running Efficiently

From |

The power supply is typically the largest processor of power in the cabinet and therefore power efficiency is an important factor.

Low-efficiency power supplies translate into extra heat in a control cabinet, which necessitates the need for a larger cooling system, resulting in higher energy consumption.
Engineers need to be aware of the efficiencies of the power supplies they design into their control systems.

Power Supply Efficiency

Power Supply Efficiency

The typical temperature within a control cabinet operating at 80% nominal power measures approximately 30°C; assuming the power supply is 92% efficient. However, if the power supply is 2% less efficient (90%), it may increase the temperature in the cabinet by as much as 10°C.

Most power supplies today have an efficiency rating above 90% but there is still room for improvement in terms of energy efficiency by the way we load our power supplies.
The best practice is to ensure that the power supply has only 50% loading.

If your project requires 5A of power, choose an efficient power supply that is able to offer 10A. This ensures that at the maximum operating capacity of the design, you are always running at 50% loading (assuming no additional loads were added to the system). But how do you know if your power supply is supplying 50% to the load? You can always use the tried and tested way of using the multimeter.

QUINT 4 LED Display

QUINT 4 LED Display

Phoenix Contact’s new QUINT 4 power supplies have onboard power LEDs displays that will let you know at what level of output your power supply is performing. The LEDs will let you now if the DC supply is “On“, performing at “>50%“, “>75%” or “>100%“. Even without a multimeter, you will be able to determine the current loading of your power supplies in real time.

In my next article, I will show you how to create a redundant, balanced power supply system that will provide you with adequate power efficiently and also extend the life of your power supply.

A Reliable, Intelligent and Powerful “Heart” – Quint 4 Power Supply Unit

From |

William_HarveyA reliable, intelligent and powerful “heart”

In the course of my work, I deal with Power Supply which is the heart of the whole electrical operation. While not all operations are the same, they cannot function without electricity, which is what makes  Power Supply units indispensable.

Quint 4The new Phoenix Contact’s Quint 4th Generation Power Supplies feature an integrated NFC interface for parameterization via mobile devices or PCs. This allows the commissioning engineer to closely match signaling thresholds and characteristic curves to the plant’s requirements. More than 40 parameters can be configured on an individual basis. Once the power supply has been parameterized, it is a simple task to transfer the settings to other devices via the app or other software, which will save effort and time for the user. Moreover, the front-panel buttons for adjusting the output voltage, as well as all other configured parameters, can be protected with a password to prevent unauthorized access and tampering.

Quint_LED

The power supply offers preventive function monitoring to allow the plant operator to run remote diagnostics on the unit to optimize plant availability. The power supply permanently monitors the output voltage and current. Critical situations are visualized using front-panel LEDs, floating relay contacts, and active signal outputs; the monitoring data is signaled to the control system before a fault actually occurs.

When the power supply unit is supplying more than the specified rated current, it is operating in boost mode. The power supply and the connected loads continue to operate normally, and the output voltage remains at 24 V DC. Preventive signaling allows early detection before a fault like this actually occurs. For instance, once a motor with a mechanical problem has been identified, it can be repaired before other loads are subjected to voltage dips.

Such preventive capabilities of our power supply units work just like how we manage our heart health to ensure we can function smoothly in our everyday operations. It is thus pivotal to ensure that we have a reliable and intelligent “heart” in the form of our trusted power supply units for our businesses.

Uninterruptible power supply with integrated power storage

From |

Compact UPS with integrated power storage

UnoUPS

In keeping with the Uno Power power supply range, the UnoUPS uninterruptible power supply is now available with a 60 W output power and integrated power storage in a compact housing.

The UPS operates flexibly at input voltages of 23 to 30 V DC. The integrated lead AGM power storage ensures long buffer times of 45 minutes at 0.5 A, for example. When combined with a Uno Power power supply from the 100 W performance class, the overall dimensions are just 160 x 90 x 90 mm. This means that this space-saving APS is also suitable for small control and distributor boxes.

The high MTBF (mean time between failure) value of over 1.9 million hours and the large temperature range of -15 to +50°C are superb features for a device of this performance class. The device also has LED status indicators for signaling and function monitoring, as well as active 24 V DC switch outputs for forwarding to a higher-level control system.
