GTF-Xtra Single-phase power controller up to 60A, with over current fault protection (Xtra)
The Gefran GTF-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 GTF-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.
GTF-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.
Suitable for use in a wide range of applications including furnaces for heat treatment, high-temperature material sintering processes, glass and ceramic production
