AMPERAGE DERATING FOR TEMPERATURE
LOAD TYPE CAUTIONARY ACTION
All load types Verify that the inrush current does not exceed the surge specifications of the SSR.
Steady-state
resistance Follow standard thermal considerations.
DC (inductive) Place a diode across the load to absorb surges during turnoff.
Incandescent
lamp Use a zero voltage turn-on characteristic.
Capacitive Verify that the rate of current rise capabilities are not exceeded. Zero voltage turn-on is an
effective method for limiting this rate.
Motors and
Solenoids Use a current shunt and oscilloscope to examine the duration of the inrush current. Verify
that back EMF does not create an overvoltage situation during turn-off.
Transformers Use a zero cross turn-on device; verify that the half cycle surge capability is not exceeded.
Rule of thumb: select an SSR with a half cycle current surge rating greater than the
maximum applied line voltage divided by the transformer primary resistance.
LOAD CONSIDERATIONS
The primary concern when using SSRs is improper heat
sinking. The type of load current should be evaluated when
considering an SSR as a switching option. SSRs alone are
not compatible with high inrush currents, but cautionary
measures can be taken in high inrush applications to
increase the SSR’s versatility.
