20A VSD - RC120D

The Powerform model RC120D Variable Speed Drive (VSD) provides electronic power control on most single phase resistive and inductive loads & provides remote electronic speed control of PSC, universal & shaded pole motors.

The speed may be varied using either a 2 wire 0 to 10 Volt Dc or 2 wire 2-20Ma control signal. Also features an internal 10 Vdc source.

It is BMS compatible, and features a low foot print for ease of installation.

The unit comes standard with two minimum / maximum adjusters for quick and simple range (span & offset) adjustments.

Also available with different mounting options and features to tailor fit your application and intended use.

Suitable for applications of single or multiple / mixed use loads up to 4800VA 20 amps 240 VAC.
