Thyristor Controllers (solid state relays) provide a means of varying the voltage for electrically resistive loads, typically electric heating elements.The RN controllers are not suitable for switching lamps due to light flicker.
Additional description Control input :0 to 10 Vdc, 0.1 mA at 10 Vdc
Control supply:
RJ :20 to 28 Vac/dc; 18 mA at 24 Vdc, 23 mA at 24 Vac
RN :12 to 32 Vdc or 21 to 27 Vac; 30 mA at 32 Vdc or 27 Vac
Current ratings:
depend on ambient temperature, nominal 30, 50 A ratings are at 25 oC (RJ), 30 oC (RN) ambient.
Voltage ratings:
230 V :90 to 265 Vac (RJ), 85 to 265 Vac (RN)
480 V :200 to 550 Vac (RJ), 190 to 530 Vac (RN)
* RJ controllers have 5 operating modes (Phase Angle, Distributed Full Cycle and Burst Control, at 1, 3, and 10 s), whereas RN controllers use a Full Cycle fixed operating mode.
