Solid State Relays

Solid State Relays (SSR) are a type of electrical relay that uses low power switching elements such as MOSFETs, TRIACs, optocouplers and other semiconductors to control high voltage and/or current loads. They are a safer, more efficient and more reliable option compared to the traditional electromechanical relay. Due to their ability to switch quickly and their adherence to high standards of durability and reliability, SSRs are commonly used for motion control, heating, lighting, process control, and other industrial applications.

One such SSR is the HA4825G, which is a 25A zero-crossing AC-controlled SSR with single phase in and single phase out. It is designed for use in applications such as motor speed control, process control and industrial ovens. The main features of the HA4825G include its compact size and high surge current capability, and its ultra-high dielectric strength. This SSR is capable of operating at ambient temperatures ranging from -40 to 125°C and is UL certified.

HA4825G Application Field and Working Principle

The HA4825G is suitable for applications that require a reliable SSR with high performance, efficiency, and safety. It is typically used in the areas of industrial automation, energy management, medical equipment, and industrial heating applications. Furthermore, the HA4825G is ideal for motor speed control, process control, thermal controllers and temperature control.

The working principle of the HA4825G is based on the solid-state switching technology. When a voltage is applied, a voltage sensitive device triggers the SSR, allowing current to pass through the SSR and control the load. The SSR will remain enabled until the voltage decreases or the current passing through either the control or the output of the SSR is turned off. The SSR\'s zero-crossing design ensures that it will not turn on until the current is at or near zero, thus reducing the possibility of switching surges.

The HA4825G also provides protection against overvoltage, undervoltage, and overcurrent conditions. It is also designed to allow for the adjustment of the current to the load, providing precise control of the load. Additionally, the HA4825G is designed to reduce electrical noise induced on the load by using external noise suppression elements and a built in noise suppression circuit.

Overall, the HA4825G is a safe, reliable, and efficient SSR designed for high performance applications. With its high current capability, compact size, and superior protection features, the HA4825G can provide reliable and precise control of the load.
