Solid State Relay 50 AA

The Solid State Relay 50 AA is a robust, high-capacity relay engineered to deliver efficient and reliable control of AC loads. Designed for industrial and commercial applications, this SSR provides an effective alternative to traditional electromechanical relays, offering noiseless operation, high switching speed, and extended durability without mechanical wear. With a rated load current of 50 Amperes and AC output, it ensures stable performance for heavy-duty operations.

This relay is built with optical isolation between the input and output, ensuring enhanced safety and protection of sensitive control circuitry. It operates with a wide control voltage range, typically 4–32 VDC input control, making it compatible with PLCs, microcontrollers, and other low-voltage control systems. Its zero-crossing switching feature minimizes electrical noise and inrush current, extending the life of both the relay and the connected load.

Engineered with durable solid-state components, the Solid State Relay 50 AA provides high dielectric strength, low on-state voltage drop, and excellent heat dissipation with the use of a proper heatsink. It is suitable for controlling resistive, inductive, and capacitive loads in applications such as heating systems, motor drives, lighting controls, and automation equipment. Compact in design and maintenance-free, it is an ideal solution for precise and reliable power switching in demanding environments.
