PS7200A-1A

Solid State Relays (SSRs) are electrical components that rely on switches and complex electronic circuitry to perform the same function as mechanical relays. The PS7200A-1A, a model from Telemecanique’s popular SSR series, is a true solid state relay that provides a reliable and cost-effective solution for a wide range of applications. In this article, we will look at the different applications of the PS7200A-1A and discuss how it works.

The PS7200A-1A is a zero-crossing thyristor type SSR, which means that it will only switch on or off when the load current is zero. This eliminates the risk of arcing and sparking when switching, increasing the reliability of the device. The PS7200A-1A is suitable for use in industrial, commercial and residential applications, and is the ideal choice for controlling motors, pumps, fans, machines, heaters, air conditioners and other such loads.

The PS7200A-1A can handle a wide range of load voltages, in either AC or DC, and can be used as either a SPST (Single Pole Single Throw) or DPST (Double Pole Single Throw) switch. It has a power capacity of 2,500VA and a current range of 0.1A to 4A. It is rated for use at temperatures between 0°C and 70°C, and can be used in high-humidity areas without any issues. The device also has a built-in indicator light that shows the status of the load.

As far as the working principle of the PS7200A-1A is concerned, the device uses a triac semiconductor in order to switch the load. The triac is a thyristor-like device, with three pins. A voltage is applied across the pins, and when this voltage reaches the breakover level, the triac switches the load on or off. The circuitry of the PS7200A-1A is designed such that it will only make the switch when the current through the load is zero.

The PS7200A-1A is a robust and reliable SSR that offers a cost-effective solution for switching loads in a wide range of industrial, commercial and residential applications. Its zero-crossing thyristor design eliminates the risk of arcing and sparking, and its internal circuitry ensures that the load is only switched when the current through it is zero. Thanks to its built-in LED indicator, keeping track of the load’s status is simple. All in all, the PS7200A-1A is an excellent choice for applications that require reliable solid state switching.
