A Solid State Relay (SSR) is an electronic switching device that allows you to control high voltage loads with low voltage signals. Unlike traditional electromechanical relays, SSRs have no moving parts, making them faster, more

A typical single-phase digital ammeter and voltmeter has four main terminals: A1 and A2: These terminals are for the input phase and neutral supply. S1 and S2: These terminals are for the current transformer (CT) connections.
