Solid State Relays

Solid State Relays (SSRs) are electronic switches that control the flow of current or voltage. They are used in a wide variety of applications, from automotive to medical, and are available in a variety of sizes, configurations, and options to suit different needs. One such SSR is the SSR-480D50, which is a 250V AC, 5A, flat type SSR designed for use in high current applications. The following explores the application field and working principle of the SSR-480D50.

Application Field

The SSR-480D50 is designed specifically for high current and voltage applications. This makes it suitable for a variety of industries ranging from automotive to medical. In the automotive industry, the SSR-480D50 is often used as a control switch for electric motors as well as for powertrain control systems. In the medical industry, it is used as a switching component for medical imaging systems, such as X-ray or MRI systems. It is also used in industrial automation, such as for controlling process pumps, fans, and automated assembly lines.

Working Principle

The SSR-480D50 is a “flat type” SSR, meaning that it operates by running an electrical current through a thin, flat semiconductor panel. This panel is electrically insulated from the environment and is made of a metal oxide semiconductor (MOS). The electrical current flows through the MOS panel, activating the SSR. When triggered, the SSR acts as a high-speed switch, allowing current or voltage to flow through it and to its load.

The SSR-480D50 can be triggered with either a voltage or current signal. When triggered, its load current does not exceed its rated amperage of 5A. The SSR-480D50 features over-voltage protection and over-temperature protection. It also features a thermal shutdown circuit, which turns off the unit if its internal temperature reaches a certain level and alerts the user of potential danger.

The SSR-480D50 has a long life expectancy of up to 100,000 operations and a response time of less than 10ms. Its compact design makes it ideal for tight spaces, and it is also RoHS compliant. Overall, the SSR-480D50 is an excellent choice for demanding high current and voltage applications.
