The reverse dielectric strength of the diode must be 10 times the circuit voltage

and the forward current must be at least as high as that of the load. If the circuit

voltage is low enough, as it is for most electronic circuits, then the reverse dielec-

tric strength of the diode can be as low as 2 to 3 times the circuit voltage.

Power supply

Varistor (AC or DC)

The method uses the fixed voltage characteristics of a varistor to prevent high

voltages from being applied to the contacts. Here, as well, the reset time will be

increase somewhat.

Connect the varistor between the load connections for 24-V and 48-V power

supply voltages and between the contact connections for 100 to 200-V power

supply voltages.

Output Surge Current

When connecting an output device having a high surge current (such as an in-

candescent lamp), use one of the following circuit configurations to protect the

Output Unit.

The following circuit lets the load draw a small current (about one third the rated

current) while the output is OFF, significantly reducing the surge current.

The following circuit reduces the surge current by employing a current-limiting

resistor.
