PS7142-1B-A

Solid state relays (SSRs) are devices used both to provide isolation between two circuits, as well as switching elements for high-current circuits. The PS7142-1B-A represents the latest generation of SSRs, delivering very high switching performance with long product life. It is designed for switching small current loads such as motor loads, as well as performing general-purpose switching applications.

The PS7142-1B-A SSR is based on IGBT, which is an insulated gate bipolar transistor. An insulated gate bipolar transistor is essentially a three-terminal structure that allows for conduction between these terminals when the insulated gate voltage reaches the conduction threshold voltage. As a result of this structure, the IGBT has very low gate drive requirements, allowing for high switching performance.

The PS7142-1B-A also features a built-in zero-crossing detector, which ensures the SSR will not switch when passing through a certain voltage threshold. This is an important safety feature, as it helps prevent damage to high current circuits. The PS7142-1B-A also has a built-in fault detection circuit, which can immediately detect any faults and shut off the SSR. This ensures that the SSR does not continue to operate in potentially hazardous situations.

The PS7142-1B-A has a wide range of application fields. It can be used to switch small loads such as motor and heater loads, as well as any other applications that require high switching performance. It can also be used for lighting control systems, power tools, home appliances, and many other applications. The PS7142-1B-A is designed for long product life, ensuring that the SSR can be used in mission-critical applications. The PS7142-1B-A is also very efficient, allowing for energy savings over time.

The PS7142-1B-A SSR has a maximum continuous on state current of 2A and a maximum inrush current of 15A. The device can be operated with an operating voltage of 15V DC - 30V DC, and is rated for a maximum dielectric strength of 4kV AC peak.

In summary, the PS7142-1B-A is an advanced solid state relay with a wide range of features and applications. Its low gate driver requirements allow for excellent switching performance, while the built-in safety features ensure that it can be used in a variety of applications without fear of damage. The device is also designed for long product life and energy efficiency, allowing for cost savings over time.
