Solid State Relays (SSRs) are a type of switch that uses a solid-state electronic component such as a semiconductor, rather than an electromechanical relay, to provide control over its switching capabilities. The SSR-480D125 is a type of SSR used in high current applications such as switching resistive or inductive loads. It provides a higher level of current and safety-related protection than other types of SSRs due to its built-in over-current protection, current limiting, and short circuit protection.

One of the key features of the SSR-480D125 is its ability to work with both DC and AC loads. Its highly reliable solid state outputs provide a low-latency response to switching and can handle overloads of up to 125A continuous and 200A inrush. The DC power level is 48V, which gives the relay a low voltage drop, providing high energy efficiency.

The SSR-480D125 is an ideal choice for applications where cost and safety are high priorities, such as industrial controllers, motor drives, power factor correction, and HVAC systems. It is designed for use in harsh environments and can operate at temperatures up to 60°C, withstanding up to 90% relative humidity. Its built-in protection features also ensure that the unit does not damage the equipment it is controlling in the event of an over-current or short-circuit.

The SSR-480D125 works on the principle of resistance heating. When it is activated, current is applied to two electrodes and the resistance between them creates heat. This heat causes the relay to open or close, depending on whether a positive or negative voltage is applied. Once the current is stopped, the relay will return to its default state. The unit also has built-in thermal protection so that if the relay is left on for too long, it will shut off automatically.

The SSR-480D125 is commonly used in applications such as elevator control, motor drives, multiplexers, and temperature control systems. It offers high reliability, with a long lifetime of up to 100,000 operations, and its compact design makes it easy to install in most systems. The wide voltage range and the ability to handle up to 125A makes it a great choice for high-current applications.

The SSR-480D125 is a reliable and efficient solid state relay, ideal for applications where cost and safety are paramount. Its highly reliable solid state outputs provide a low-latency response to switching and can handle overloads of up to 125A. Its built-in protection features ensure that the unit does not damage the equipment it is controlling in the event of an over-current or short-circuit. Its application fields span a wide variety of environments and the unit is designed to provide long lasting, reliable performance.
