The REOTRON EW 514 is a single-phase thyristor power regulator for load currents up to 6 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.
Variation of the mains supply are compensated by an internal control circuit.

The unit is mounted to a 35 mm rail to DIN EN 50 022.
