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.
The 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.
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.
