THE SVTA4690 from Practical Control Solutions (PCS) is a three-phase, phase angle control SCR module suitable for controlling resistive heating loads, transformers, and motors.

Resistive loads of up to 50 amps and motor loads of up to 22 amps can be accommodated. Soft starting and soft stopping functions are included.

The control input signal is 0-10V dc. The output is proportional to the control input, with the output settable to either phase angle or rms voltage.

The unit can operate at voltages from 200 to 480V ac and from 40 to 65Hz. The load may be star or delta connected.

PCS can supply complete SCR assemblies with heatsink, fan (when required) and semiconductor protection fuses.
