Working Principle of ASSR-1510-503E

The working principle of ASSR-1510-503E is based on the principle of electronic switching. When the control terminal voltage of the relay is below the turn on voltage, the input terminal voltage is isolated from the load terminal. When the control terminal voltage is above the turn on voltage, the input terminal voltage is connected to the load terminal side due to the closed state of the thyristor.

When the control terminal voltage drops below the turn off voltage, the thyristor break-over occurs, the input terminal voltage is interrupted from the load terminal, and the relay is switched to OFF state. The external control terminal voltage can be voltage or current, and a small control voltage can switch on and off a high current load.

Conclusion

The solid state relay ASSR-1510-503E developed based on advanced semiconductor technology, has many advantages over traditional mechanical relays, such as fast response time, high durability, and no need for charing. The ASSR-1510-503E has wide applications in industrial automation, automotive engine speed control, building air conditioning management and other fields. The working principle of ASSR-1510-503E is based on electronic switching, which uses a small control voltage that can switch on and off a high current load.
