PS7200H-1A-E3-A

Solid State relays (SSRs) are becoming increasingly popular tools for controlling electrical circuits. In particular, the PS7200H-1A-E3-A SSR is a reliable device used in many applications. This article discusses the application field and working principle of this SSR.

What is the PS7200H-1A-E3-A SSR?

The PS7200H-1A-E3-A is a type of Solid State Relay (SSR) that can be used in applications requiring high speed switching, as well as noise immunity. This single-pole type SSR has an input voltage range of 12-28 VDC, an output voltage range of 0-250 VAC, and a continuous current rating of 1A. It also has an insulation resistance of 1kVrms between each terminal and the earth ground.

Application Field of the PS7200H-1A-E3-A SSR

The PS7200H-1A-E3-A SSR can be used in a variety of applications. The SSR\'s high speed switching feature is especially advantageous for motor control and machine control applications. The SSR can also be used in alarm systems, monitoring systems, lighting control, and in automation circuits. Additionally, the SSR is well-suited for use in industrial environments, and can be used in hazardous areas.

Working Principle of the PS7200H-1A-E3-A SSR

The PS7200H-1A-E3-A SSR works on the principle of zero-cross switching. This means that when the input signal of the SSR changes, then the output voltage of the SSR changes at the point of zero crossings of the AC power supply. This helps minimize the power loss in the switching process. The SSR also utilizes an SCR (silicon-controlled rectifier) module as the switch, and the SCR module is triggered by the signal from the system.

The SSR also utilizes a heat sink, which helps dissipate the heat generated from the SCR. The heat sink is also designed to minimize the noise generated from the SSR\'s operation. Additionally, the SSR is designed with a two-way over-current protection and a three-way over-voltage protection circuit.

Summary

The PS7200H-1A-E3-A is a reliable Solid State Relay (SSR), used in a variety of applications, including motor control, machine control, alarm systems, lighting control, and automation circuits. The SSR operates on the principle of zero-cross switching, and utilizes an SCR (silicon-controlled rectifier) module, as well as a heat sink, to help dissipate the heat and reduce the noise generated during operation. The SSR also features two-way over-current protection and a three-way over-voltage protection circuit.
