Gefran
Intelligent control and measurement technology
Gefran has developed the scalable 'GRx' family of power controllers specifically for controlling industrial heating applications.
The GRZ-H solid state relay series from Gefran was designed for controlling three-phase heaters. Features of this series include three-pole control for controlling all three phases, two-pole control (economy circuit) with looped-through third phase and integrated protection against overtemperature and overvoltage. The series is available for currents from 10 to 75 A per phase and AC voltages up to 600 V.
Equipped with an IO-Link interface, the GRM-H series offers single-phase power controllers that can also be used to control three-phase loads in a master/slave configuration. The devices offer a current range from 15 A to 120 A and enable the control of linear and non-linear loads (MoSi2, SiC SWIR, graphite and transformers).
The GRP-H single-phase solid-state relays are available for a current range from 15 A to 120 A and support the digital IO-Link protocol.
