1026 Single Phase Zero-Cross SCR Analog Controller

The model 1026 is a single phase, zero-cross, solid state contactor replacement. The model 1026 re- sponds to an AC command signal of 120 or 240 Volts.

The command signal is electrically isolated from the line and load voltage.

The 1026 circuit provides the proper loading to triacs and other solid state switching devices to insure correct turn-on of the switching device and to insure that the leakage current from these devices when in the off state does not cause false operation of the SCR.
