Autonics SR1-N Series Type SSR Single Phase Separated Heatsink

Input 90-240VAC, Load 24-240VAC, 50A, Zero cross

The single phase solid state relays SR1 series feature compact, universal designs for flexible installation and detachable heatsinks for easier maintenance or replacement. The high dielectric strength of 4000 VAC provides durable and reliable performance in various applications, including heater loads, semiconductor equipment, and motor control.

4,000 VAC High Dielectric Strength

The high dielectric strength of 4,000 VAC provides durable and stable performance.

High Heat Dissipation Efficiency with Ceramic PCB

Ceramic PCB's offer better electrical isolation and thermal conductivity compared to metal core PCB's, offering better heat dissipation efficiency.

Zero Cross Turn-On

The relay switches ON/OFF when the voltage reaches the zero-crossing point of the sine wave.
This method minimizes surge current and inrush current, and is ideal for most common industrial loads.

Random Turn-On

The relay opens or turns on immediately when the input signal is applied and turns off when the signal is removed.
This method allows phase-control applications requiring precise control of power.

Check Operation Status

Easily check the operation status of the unit with the input indicator (green LED).

Applications

Solid state relays used in conjunction with temperature controllers in cup sealing/packaging machines.
