Single-phase Thyristor Controller Reotron Ew 514

Single-Phase Thyristor Controller


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. The matching of load power to the required setpoint range is affected by internal trimmer potentiometers for Umin/Umax. Remote control of the unit is possible by means of an enable/inhibit input.
Variations of the main supply are compensated by an internal control circuit.

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