Product Information

2022 is a single phase, phase angle SCR power controller with two remotely-selectable inputs. It accepts command signals of 0-5 VDC, 0-10 VDC, or a potentiometer. 2022 can be made to accept a 4/20 mA current loop command with the addition of a resistor (R27 or R28) to the circuit. 2022 also controls the RMS voltage to the load proportional to the command signal, independent of line voltage changes.

Some features include:

Line voltage compensation holds load voltage constant with changes in line voltage
Soft-start for transformer loads.
Missing cycle detection.
Can be used with all load types.
Dual command setpoints.
Compact and economical
2500 VAC RMS isolation between input/output and line voltage/heatsink.
Natural convection.
