Solid-State Relays In Series
In applications requiring greater current rating at higher voltage,
two Opto 22 SSRs may be operated in series for double the
voltage rating. The built-in snubber in each SSR assures proper
voltage sharing of the two SSRs in series. In the diagram below,
two 240-volt, 45-amp SSRs are connected in series for operation
on a 480-volt line. The control is shown with a parallel hook-up
but it should be noted that a serial connection can also be
implemented.
Lamp Loads
Since all Opto 22 SSRs are zero voltage switching, they
are ideal for driving incandescent lamps because the
initial inrush current into a cold filament is reduced.
The life of the lamp is increased when switched by a
zero voltage turn on SSR. The following table is a guide
to selecting an Opto 22 SSR for switching a given
incandescent lamp.
Heater Loads
Care should be taken in selecting a SSR for driving a heater 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 eliminate thermal fatigue
failures. In addition, Opto 22 recommends operating any SSR at 75%
rated current for cycling heater loads to ensure complete reliability.
The following table is a guide to selecting the proper SSR for a given
heater load.
