Continuous and precise control of electrical resistors for industrial heating applications requires reliable, compact, fast with integrated diagnostic Solid State relays.
The GRS-H series of Solid State Relay with heat sink, current ratings from 15 to 120 Amperes, voltages up to 660Vac, zero crossing switching (ZC) and in ultra compact sizes is the ideal device for this type of application. The high efficiency heat sinks guarantee for all models the continuous supply of the rated current at a working temperature of 40°C, supported by fans for the 90A and 120A models.
