The model 3026 is a three-phase, zero-cross SCR controller capable of accepting ON-OFF control signals from 6 Vac to 240 Vac.

 

When a control signal is applied, power to the load is turned on at the beginning of the next electrical cycle. When the control signal is removed, the power to the load is turned off at the end of the next electrical cycle. Power is, therefore, always applied and removed from the load when the instantaneous supply voltage is zero.

 

The 3026 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 controller.

 

The control signal is isolated from the line and load voltages, and all are isolated from the heat sinks.
