SR1 Series

Description

Single-Phase Solid State Relays (Detachable Heatsink Type)

The SR1 series single phase solid state relays feature compact, universal designs for flexible installation and detachable heatsinks for easier maintenance or replacement. The solid state relays provide durable and stable control, for optimal performance in various applications including heater loads, semiconductor equipment, and motor control.

Main features

  • Compact, universal design for flexible installation
  • High heat dissipation efficiency with ceramic PCB
  • Zero cross turn-on, random turn-on models available
  • Input indicator (green LED)

※ The SR1 series has been updated (SR1-ㅁㅁㅁㅁ-N). Please check specification details before use.

  • Efficient Heat Dissipation

  • Input Indicator

High Heat Dissipation Efficiency with Ceramic PCB

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

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 power control.

Check Operation Status

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