A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay, but as solid-state electronics contain no moving parts and have a longer operational lifetime.
Our SSRs use power semiconductor devices such as thyristors and transistors, to switch currents up to around a hundred amperes.
