There is no problem for SSR to switch on/off the normal loads, but some special load conditions should also be considered so as to avoid the unnecessary damages to the device caused by excessive impact current and overvoltage. In the use, the steady-state current flowing through SSR output should not exceed the rated output current under relevant temperature as stipulated in the product specifications. The possible inrush current cannot exceed the overload capacity of the relay. Generally, there should be some margin.

DC solid state relay is only suitable for controlling DC power and load, AC solid state relay is only for controlling AC power and load, and AC/DC universal(bidirectional)solid state relay is applied to AC, DC and bidirectional square wave control.

The voltage of load power supply can't exceed rated output voltage of solid state relay, and can't be lower than stipulated minimum output voltage. The maximum value of voltage peak which is possibly added to solid state relay should be lower than the value of its transient voltage.

ATO provides two types of solid state relays, DC and AC input control. DC control input all use constant current source circuit, with input voltage range of 3-32V DC, convenient to connect with TTL circuit and microcomputer interface. The positive and negative polarity of control terminals should be paid attention to under installation. AC control input of solid state relay is also available with control voltage ranging from 70 to 280V AC.
