The JM series is a single-phase thyristor regulator that receives signals from a controller, PLC, or manual setting device and adjusts the power supplied to the heater of an electric furnace.
Rated current from 10A to 500A are available, so you can select the capacity that matches the heater rating.
RS-485 (MODBUS) communication function is standard.
