Transformer Loads
of the proper SSR for driving a given transformer. Transformers
are driven from positive saturation of the iron core to negative
saturation of the core each ½ cycle of the alternating voltage.
Large inrush currents can occur during the first ½ cycle of line
voltage when a zero voltage SSR happens to turn on during the
positive ½ cycle of voltage when the core is already in positive
saturation. Inrush currents greater than 10 times rated trans-
former current can easily occur. The following table provides a
guide for selecting the proper SSR for a given transformer rating.
Solenoid Valve and Contactor Loads
as solenoid valves and electromechanical contactors. The built-in
snubber in each SSR assures proper operation into inductive
loads. The following table is a guide in selecting an SSR to drive
a solenoid or contactor.

Control Current Calculation
of 1000 ohms in series with an LED. Since 3 volts is required to turn
on any SSR, the maximum current required is (3 volt - 1 volt) divided
by 1000 ohms which equals 2.0 mA. The 1 volt is subtracted from
the 3 volt signal because 1 volt is dropped across the LED. For higher
control voltages, an external resistor can be added in series with the
control voltage to limit the control current. To limit the control cur-
rent to 2 mA, calculate the external resistor R
= the control voltage.
The DC control voltage range is 3–32 VDC. To calculate the control
current for any voltage within the 3–32 VDC range, use the formula:
