DESCRIPTION

The S48A25 is a Series S single-phase solid-state relay designed for AC/DC control applications with zero-cross turn-on switching. It features a 480 Vac nominal line voltage with an operating range of 24 to 520 Vrms and supports 75A output current for resistive loads. The relay incorporates AC control with a control voltage range of 90 to 240 Vac/Vdc, optical isolation for transient protection, and an internal snubber for output protection. With a zero-cross window of ±12 Vac, low off-state leakage current of 3 mA, and turn-on/off times of 24.9 ms, this relay is well-suited for heating control, motor control, industrial process control, and uninterruptible power supply applications.
