Solid State Relay, DC control AC, SSR-D4810/4825/4840/4860/4880/48100/48120

Solid state relay (SSR) is an advanced industrial control device that uses power semiconductor components as the main control component.  Compared with traditional magnetic contact industrial controllers, solid-state relays have higher power, intelligence, digitalization, and systematization, which contribute to green development.  SSRs are available in different switching modes, including zero-crossing and random types.  The random type turns on immediately after receiving the input control signal, while the zero-crossing type requires the load voltage to reach the zero area before turning on.  Both types can be cut off when the current falls below the maintenance level.  The zero-crossing type may cause maximum half-cycle delay, but reduces load effects and RF interference, making it an ideal switching device.  Random types, on the other hand, respond quickly and are suitable for dimmers, thermostats, resistive loads, and some inductive load applications.

When turning off the SSR, the triac may experience a large rate of rise (dv/dt) if the phase currents and voltages are different.  If the dv/dt exceeds the Triac standard (300V/us), it may cause delayed shutdown or failure.  Using a powerful SSR with anti-parallel thyristors can significantly increase dv/dt (up to 500V/us), making it suitable for capacitive or inductive loads.  For loads above 40A, it is recommended to use powerful SSR.  Zenli's SSRs above 40A are all powerful types.
