P0142-14L is a DC controlled, AC random-turn-on, zero-switching solid-state relay. It is suitable for control systems with short turn-on time and fast switching speed. When the zero-type solid-state relay is used for inductive loads such as transformers, it will cause a large surge current. Using a random-turn-on solid-state relay is one solution. It can turn on the output device at any time in the first half cycle. This start-up method significantly reduces the start-up opportunities under harsh conditions and improves the life of the solid-state relay. Especially for three-phase motors and other three-phase loads, to make multiple solid-state relays that execute control simultaneously connected, the use of random AC solid-state relays is more suitable. It also has zero-current turn-off, which can reduce the back electromotive force of the inductive load at turn-off, which has certain protection for the load and the solid-state relay. It can also be used with phase triggers to provide phase shifting.
The document describes the P series solid state relay, its features and operation. It explains how the relay can be triggered at any phase and its fast switching characteristics, making it suitable for inductive loads.
