load if the load is cycled on and off in a continuous manner as might
occur in a temperature control application. Constant cycling can
cause thermal fatigue in the thyristor chip at the point where the
chip bonds to the lead frame. Opto 22 employs a thick copper lead
frame for mounting the SCR chips in the power series SSRs to elimi-
nate thermal fatigue failures. In addition, Opto 22 recommends
operating any SSR at 75% rated current for cycling heater loads to
ensure complete reliability.

inductance and the phase shift capacitor can cause twice line volt-
age to appear across the open SSR. A 240-volt SSR should be used
for a 120-Volt line. During the transition period when one SSR is
turned on and the other SSR is going off, both SSRs may be on. In
this case, the capacitor may discharge through the two SSRs, caus-
ing large currents to flow, which may destroy the SSRs. The addition
of RL as shown will protect the SSRs from the short circuit capacitor
discharge current.
The resistors are unnecessary if the control circuit is designed

The circuit diagram illustrates a typical 1 Ø motor winding
to ensure one SSR is off before the other SSR is on.
