1039I

The 1039I is available as a Custom OEM model only. Contact the factory for more information.

The model 1039I is a phase-angle SCR power controller for use in a single phase application. The power applied to the load is linear with respect to the command signal.

Available command signals include 0 to 5Vdc, 0 to 10Vdc, 4 to 20mA or potentiometer.

The 1039I is available with current ratings from 10 to 180 amps and voltage ratings from 120 to 575Vac. The controller will operate without adjustment or modification on 50 or 60 hertz.

The 1039I circuit uses a digital phase locked tim- ing technique to accurately determine the turn on time of the SCRs.
