Tips: How to choose a SSR in different loads?
It is not be a problem to choose a suitable SSR for normal loads, but special load conditions must also be considered so that excessive impact current and overvoltage as well as unnecessary damages caused to device performance are avoided. The feature of cold-state resistance of filament lamps, electric furnaces, etc. result in surge current at the turn-on moment, which is several times higher than the rated working current value. Generally, ordinary-type SSRs may work properly at the point of 2/3 of its rated current value. Enhanced SSRs may be selected according to the parameters provided by the manufacturer. In the harsh conditions such as industrial control sites, it is recommended to leave enough voltage and current margin.
