NOTE

When used for the load less than rated

In the case of the load current less than rated, malfunction may result from the residual voltage across the both ends of the load even if the solid state relay is turned off.

Use a dummy resistor as a countermeasure.

The total of the current through the resistor and the load current must exceed the min. rated load current.

In case the dummy resistor is not used, keep in mind that the residual voltage becomes as follows:

Example:

For the inductive load by the 5 mA load current and the 200 V AC load voltage, the load impedance becomes 40 kW and Ve/V = 16% is estimated from the below graph.

Accordingly, the 32 V voltage remains across the both ends of the load when the solid state relay is turned off.
