GFW Xtra Single/Bi/three-phase power controller up to 100A, with over current fault protection (Xtra)
- The Gefran GFW-Xtra power controller combines the functionality of a single, two, or three-phase solid-state power unit and controller with the benefits of the unique integrated overcurrent fault protection function.
- The fault protection eliminates the need for extra-rapid fuses, reducing machine downtime and the cost of replacing fuse failures. It does so by instantaneously monitoring load current, cutting the power if the load reaches a pre-set threshold, and isolating the power switching devices.
- In applications susceptible to intermittent short-circuits and overloads, the Gefran Xtra power controller can be programmed to restore power automatically when the fault has cleared, preventing complete process shutdown and maintaining production.
- Alternatively, power can be manually restored, locally or remotely.
- A soft-start ramp is applied when the current is restored, to prevent system damage in the event that the fault is not effectively cleared.
- The GFW-Xtra controller is compact, modular, and optimized to control virtually any type of restive heating system in a wide range of industrial applications. Impressive functionality is assured by a comprehensive array of options that are configurable with intuitive, guided-set-up, PC-based Windows software.
- GFW-Xtra always provides an RS485 serial connection with Modbus RTU protocol to control currents, voltages, powers, load status, and device status from the supervisor terminal (HMI) or PLC.
- A second (optional) communication port is offered that lets you choose from among the following Fieldbuses: Modbus RTU, Profibus DP, CANopen, Modbus-TCP, Ethernet IP, EtherCAT.
- Suitable for use in a wide range of applications including furnaces for heat treatment, high-temperature material sintering processes, glass and ceramic production
