Single Solid State Relay

  A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSRs consist of a sensor which responds to an appropriate input (control signal), a solid-state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. The relay may be designed to switch either AC or DC to the load. It serves the same function as an electromechanical relay, but has no moving parts.

  Packaged solid-state relays use power semiconductor devices such as thyristors and transistors, to switch currents up to around a hundred amperes. Solid-state relays have fast switching speeds compared with electromechanical relays, and have no physical contacts to wear out. Application of solid-state relays must consider their lower ability to withstand momentary overload, compared with electromechanical contacts, and their higher "on" state resistance.


single DC TO DC SSR

single DC TO DC SSR

This Solid State Relay SSR-10DD TO SSR-80DD can switch current loads of up to 10-80A with a 3-32V DC Input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.

single DC TO AC SSR

single DC TO AC SSR

This is SSR-10DA TO SSR-150DA Single-phase Soild State Relay. It can be driver by Arduino directly without any expanding circuit because of its built-in opto-couple. The plastic protective cover makes it be a safer relay module.

Single AC TO AC SSR

Single AC TO AC SSR

This Solid State Relay SSR-10AA TO SSR-150AA can switch current loads of up to 10A-150A with a 80-250V AC input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.

The solid state voltage regulator (SSVR) is for manually regulating the AC power. It works in the same way as a dial on an electric stove, or a dimmer for ceiling light. The main difference for the SSVR is that its power handling capability is much larger than a dimmer

solid State Relay (SSR) is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control end and the load end. The input terminal of the solid state relay uses a tiny control signal to directly drive a large current load.
