Solid State Relays (SSRs) are electrical devices used throughout industry as an electrical interlocking device, controlling the power supply to connected electrical devices, such as motors and lights. The G3RV-SR500-AL AC/DC48 SSR is a specific type of SSR that can be used in a variety of applications, and has a simple yet efficient working principle.

Application Field

The G3RV-SR500-AL AC/DC48 SSR is primarily designed for controlling power supply between 130V AC and 48V DC to motor drives, electric lighting, heating elements and various other appliances. It is particularly suited for switching motor loads, and can be used in a wide variety of industrial applications.

This SSR is suitable for use in high ambient temperature environments, usually >85°C, thanks to its aluminum case and heat sink. The SSR can withstand up to 4kV of electrical surge, and comes equipped with over-current and over-temperature protection for enhanced safety. It is available in both SPST-NO and SPDT-NO configurations, giving it a wide range of possible uses.

Working Principle

The working principle of the G3RV-SR500-AL AC/DC48 SSR is relatively simple. It consists of a power semiconductor switch, which is usually a thyristor or a triac, and a compact radiator to dissipate the heat generated during operation. When the SSR is switched on, the semiconductor switch closes a circuit allowing the current to flow through. When the SSR is switched off, the semiconductor switch opens the circuit and breaks the current.

The G3RV-SR500-AL AC/DC48 SSR is controlled by an input that is usually a voltage or current signal. The signal can be used to control the power output of the SSR, depending on the type of signal used. Voltage based inputs are the most common, as they are easy to control and are triggered when given a specific threshold value. Current input signals, like those from a potentiometer, are used in some applications, but are less common and more difficult to control.

The G3RV-SR500-AL AC/DC48 SSR has a range of features to make it suitable for a variety of applications. It has a low power consumption of only 0.7W at no load and a maximum power consumption of 4.7W. It has a good surge resistance of >4kV, and an operating temperature range of -20°C to +85°C. The G3RV-SR500-AL AC/DC48 SSR is a simple, high performance solid state relay, suitable for a wide range of industrial applications.
