About This Product

■Summary

The SR2/3 series, a 2/3-phase heat sink separated type SSR, has two types of mounting holes and can be mounted on a variety of heat sinks, and an alarm output is activated when the internal temperature rises, making the product safer. can be used. In addition, the range of product selection has been expanded by providing a 24VAC low voltage input model, and safety has been improved by achieving a maximum withstand voltage of 4,000VAC.

■Features

・Two types of mounting holes are provided. ・Alarm function (overtemperature detection): Alarm output indicator (red LED), output cutoff, alarm output ・Excellent withstand voltage: 4,000VAC (2,500VAC for some models) ・Rated input voltage: 4- 30VDC, 24VAC, 90- 240VAC ・Rated load voltage: 24- 240VAC, 48- 480VAC ・Rated load current: 15A, 30A, 40A, 50A, 75A ・Maximize heat dissipation efficiency by using a ceramic substrate ・Achieve precise control with zero cross turn-on/random turn-on method ・Input status can be confirmed with input indicator light (green LED)

■Two types of mounting holes are provided.

It can be mounted on a variety of heat sinks by providing two types of mounting holes. Improved ease of attachment to the product.

■Built-in alarm function (overtemperature rise detection)

If the internal temperature rises due to internal damage or overcurrent, the alarm output will activate and the red LED will light up, allowing you to use the product more safely.

■Provides low voltage model and achieves maximum 4,000VAC withstand voltage

We offer a 24VAC low voltage input model, expanding the range of product selection, and with a maximum withstand voltage of 4,000VAC, it provides high safety and reliability. Support for zero cross turn-on/random turn-on method

■Zero cross turn-on

The zero-cross turn-on method, which turns on and off near zero voltage, generates less noise by suppressing inrush current and transient current, allowing precise power control.

■Random turn-on

The random turn-on operation method, which turns on when an input signal is input and turns off near zero, enables precise power control because phase control is possible.

■Operation status can be confirmed

The input indicator (green LED) makes it easy to check the operating status.
