Autonics SR3 Series Three-Phase Solid State Relays (Detachable Heatsink Type)

SSR, Detachable Heatsink Type, 3-Phase(3-Pole), Input 4-30VDC, Load 24-240VAC, 50A, Zero Cross Turn-On

The SR2/3 series three-phase solid state relays are detachable heatsink types, which can be used with various heatsinks. The solid state relays can control 2-phase or 3-phase loads and feature two mounting hole types for compatibility with various types of heatsinks. The series also features alarm output for safe operation, and are also available in 24 VAC low voltage models. Select models feature high dielectric strength of up to 4000 VAC.


Two Mounting Hole Types	Alarm Output	Low Voltage Input	Dielectric Strength (Select Models)	Screw Mount	DIN Rail Mount

Two Mounting Hole Types

Two different mounting holes types and sizes allow flexible installation and mounting on various types of heatsinks.

Built-In Alarm (Overheating) Function

In case of overheating due to product damage or overcurrent, the alarm output turns on and the red LED indicator provides safer operation for users.

Low Voltage Models Available/Dielectric Strength Up to 4000VAC

24VAC low voltage models are available for flexible application in diverse settings. Select models feature high dielectric strength of up to 4000VAC.

Zero Cross Turn-On/Random Turn-On Models Available

• 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.

Status Indicators

The input indicator (green LED) allows users to quickly identify the operation status of the relays.

Applications

Solid state relays used for temperature control of SMT machinery

Dimensions

Detachable heatsink type

Integrated heat sink (rated load current 15A/30A/40A)

Integrated heat sink (rated load current 50A)

Integrated heat sink (rated load current 75A)
