POWER / VOLTAGE REGULATOR RH-12 / RV-12 Regulator RH(V)12 is dedicated to adjust the voltage supplied for the different electric loads (motors, heaters, lighting). Performs phase control. It is designed to work with the controller with continuous output - ver. RV or you can adjust the potentiometer on the unit - ver. RH. Inputs and outputs are galvanically isolated (Ui=2500 Vac). All versions have a built-in snubber RC for protectection of the triak. Housing mounted on the DIN rail En520035 . Application for Control: - temperature electric ovens, U-min LED CTR - linear or spot welders, - primary-side voltage transformers, - lighting, - fan speed, mixer speed, etc. RH-12 N A1 L TECHNICAL DATA Output LOAD 12 A Power supply 195...230...253 V a.c.
