P series solid state relays are DC or square wave input at the control end, and AC random type output. The characteristics are that when the DC or square wave input at the control end is input, the output device is turned on immediately regardless of the phase. Suitable for control systems that require short turn-on time and fast switching speed.

They have smooth startup performance, low radiation interference to the power grid, and provide protection for appliances and solid state relays. They are suitable for controlling motors, heaters, incandescent lamps, etc.

This document describes the features and characteristics of the D series solid-state relays produced by Shenyang Bestall Electronic Equipment Research Institute. They are mainly used for DC level conversion, isolation, and control, and are widely used in the field of industrial automation.

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.
