REOTRON EW 509
REOTRON EW 509 is a single-phase thyristor power regulator for load currents up to 15 A.
The control electronics are isolated from the mains voltage. Load power is controlled by means of thyristors operated in the phase-angle control mode.
The setpoint signal can be provided either by a potentiometer, or by a 0...+ 10 VDC or a 0(4)...20 mA control signal. Matching of load power to the required setpoint range is effected by internal trimmer potentiometers for Umin/Umax.
Remote control of the unit is possible by means of an enable/inhibit input. An internal control circuit compensates variations of the mains supply. The unit is mounted to a 35 mm DIN rail
according to EN 50022-35.
