3037 Three Phase Power Controller

The model 3037 is a two-leg, three phase, Zero Cross SCR power controller. The controller provides control of electrical power to resistive loads by means of silicon controlled rectifiers connected in two of the three lines. Control of power is linear with respect to a command signal. The command signal is electrically isolated from the line and load voltage.

The controller features a compact design, a single plug-in circuit card for ease of operation, and an electrically isolated heatsink. All three line leads are fused. The unit accepts 4-20mA, 0-5Vdc, 0-10Vdc or potentiometer command signals. The 3037 has shorted SCR detection built in as an added feature.
