• Solid state relay consists of three parts
  • Input Circuits

 Resistive input circuits are used to control signals with fixed control voltage.

• • Isolated Coupling

Solid-state relay input and output circuit isolation and coupling methods are photoelectric coupling and transformer coupling.

• • Output Circuit

The power switch of SSR is directly connected to the power supply and the load side to realize the on/off switching of the load power supply.

•  Low noise

AC type SSR adopts over-zero trigger technology, so the line effectively reduces the voltage rise rate dv/dt and current rise rate di/dt value, so that the SSR long-term work on the utility interference is very small.

•  Short switching time, about 10ms, can be applied in the higher frequency occasions.
•  Optoelectronic isolation between the input circuit and the output circuit, insulation voltage of 2500V or more.
•  Low input power consumption, compatible with TTL and COMS circuits.
•  Protection circuit at the output.
•  High load capacity.
