Surge Voltage Protection for PV Applications with UL and Kema Approvals
From |VAL-MS…DC-PV surge arresters from Phoenix Contact, designed to protect photovoltaic systems against lightning and surge voltages, now have UL and Kema approvals.
Intelligent UPS Now Also Communicates with Higher-Level Controllers
From |IQ technology turns Phoenix Contact’s Quint UPS-IQ power supply into an intelligent UPS for the mounting rail that provides continuous information about the charging state, remaining runtime, and lifespan of its energy storage devices, thus maximizing system availability.
The new data cable now allows the UPS module to be integrated directly into the automation application.
Universal Type 3 Surge Voltage Protection for Devices
From |The new BT-1S-230AC/O type 3 protector from Phoenix Contact offers surge voltage protection for loads in single-phase power circuits with 230 V AC nominal voltage. The main areas of application for these universal modules are installation sockets, dado trunking, underfloor installations and connection spaces in end devices.
Fast Profibus Extender with Surge Protection
From |The new Profibus extender from Phoenix Contact enables straightforward integration of remote Profibus devices at data rates of up to 1.5 Mbps. The extender has two DSL connections per device. This means that in addition to point-to-point connections the extender can also be used to easily establish line structures with up to 30 devices.
Active Redundancy Modules Decouple, Monitor, and Control
From |Two active Quint Oring redundancy modules are new in the Phoenix Contact product range. They increase the operational reliability by monitoring the redundant power supply solution from the output voltages of the power supplies through the power supply wiring up to the load, as well as the decoupling section up to the load current.
Intelligent Uninterruptible Power Supply for the Control Cabinet
From |A new generation of uninterruptible power supplies now supplements the Quint Power product family from Phoenix Contact. Five new modules that can be snapped onto mounting rails are now available: For 24 V loads, the Quint UPS-IQ uninterruptible power supply has output currents of 5, 10, 20, and 40 A – and for loads with an input voltage of 85 up to 264 V AC, the Quint UPS-IQ supplies an output power of 500 VA.
DC/DC Converters for Cost-Effective Protection using Circuit Breakers
From |DC/DC converters in the Quint Power design are new additions to the Phoenix Contact product range. Employing Selective Fuse Breaking (SFB) technology, these high-quality voltage converters reliably trip standard circuit breakers. Faulty circuits are selectively shut down, the fault is localized, and important system components remain operational.
Preventive Maintenance with Lightning Current Monitoring
From |The Lightning Monitoring System LM-S from Phoenix Contact provides information online about lightning strikes in plants and systems. As a consequence, service call planning can be optimized. This new system identifies and analyzes all of the important parameters of lightning surge currents based on the Faraday effect.
Lightning Arresters for LTE and WiMax Antennas
From |The demand for mobile Internet services is forever on the rise. Thanks to WLAN, it is possible to surf in the global network in nearly all buildings and major metropolitan areas. However, network coverage can be spotty outdoors, in public spaces, and especially in rural areas.
