K2CU

Heater Element Burnout Detector

K2CU

Accurate Detection of Heater Element Burnout Regardless of Heater Capacities

K2CU-F[][]A-[]GS Model with Gate Input Terminals

Control supply voltage Operating current
4 to 10 A 8 to 20 A 16 to 40 A 32 to 80 A
100 VAC With voltage
fluctuation compensation
K2CU-F10A-CGS K2CU-F20A-CGS K2CU-F40A-CGS K2CU-F80A-CGS
110 VAC K2CU-F10A-DGS K2CU-F20A-DGS K2CU-F40A-DGS K2CU-F80A-DGS
200 VAC K2CU-F10A-EGS K2CU-F20A-EGS K2CU-F40A-EGS K2CU-F80A-EGS
220 VAC K2CU-F10A-FGS K2CU-F20A-FGS K2CU-F40A-FGS K2CU-F80A-FGS

Note: A model with a gate input terminal is required to combine the K2CU with a temperature controller that uses PID
          control for temperature control of a heater. To do so, use a temperature controller with a voltage output.
