Transformer Coupled Type Solid State Relay


Transformer Coupled Type Solid State Relay, Transformer Coupling SSR uses a transformer as an isolation device. The transformer can convert the low power control signal from the primary coil to the secondary coil to generate a signal for driving the electronic switch. And if the input control signal is a DC voltage, a converter is required in the input circuit. After processing by rectification, amplification or other modifications, the signal from the secondary coil can be used to drive the switching component.
