Gefran GRM-H NEW Compact single phase Power Controller up to 120A

GF-GRM-H

The GRM power controller is designed for complex loads like infrared lamps and Silicon Carbide heating elements, which can have variable current requirements, especially during startup. The GRM continuously monitors and uses algorithms to control current absorption, ensuring stable energy supply, compensating for voltage fluctuations, and preventing breakdowns or downtime.

  • Compact size from 10A to 120A
  • Load voltage 480V, 600Vac
  • IO-Link and Modbus RTU digital communication
  • Configurable control mode Zero Crossing, Burst Firing, Half Single Cycle or Phase Angle
  • Feedback V,I,V2, I2, P, Z
  • Logic command Vdc, Analog, PWM or IO-Link
  • Configuration and Diagnostics via smartphone App with NFC technology

Product Overview:

GRM-H
Control
The availability of several configurable firing modes (ZC, BF, FT, HSC, PA) combined with features that ensure stable energy delivery to the load such as compensation for mains voltage fluctuations or aging of heating elements allow efficient temperature management resulting in energy optimization of the process.

Digital communication protocols
Factory digitization is now reaching its final frontier, the field level of industrial automation. By selecting a GRM-H power controller with either IO-Link or Modbus RTU communication protocols, users have valuable process data for predictive maintenance and using machine learning in their shop.

NFC configuration
Simple and safe commissioning, fast maintenance and diagnostics are a requirement today for devices such as Power Controllers. The GRM-H series, thanks to NFC technology, makes it possible to extend user interaction by using standard Smartphones or Tablets as smart configurators. Thanks to a graphical and intuitive interface, setup or diagnostics are particularly intuitive. (Download from Apple Store/ Google Play Store)
