The Carlo Gavazzi RM1A48A50 is a high-performance 1-phase Solid State Relay (SSR) designed for demanding industrial applications. Featuring zero-cross switching for reduced electrical noise and enhanced longevity, this relay offers a robust solution for controlling loads up to 50A at 42-530 Vac. Its compact design includes an IP20 protection cover, built-in varistor for overvoltage protection, and direct copper bonding technology for superior thermal management. With a wide control voltage range of 20-280 Vac or 22-48 Vdc, and LED indication, the RM1A48A50 provides reliable and efficient power switching.The Carlo Gavazzi RM1A48A50 is a single-pole, single-phase Solid State Relay (SSR) with a rated current of 50A (AC RMS) and an operating voltage range of 42-530 Vac (480 Vac nominal RMS). It features zero-cross switching and is designed for panel mounting. The control voltage can be AC (20-280 Vac) or DC (22-48 Vdc). The relay includes an LED indicator, built-in overvoltage protection, and an IP20 protection cover. It supports self-lifting screw-clamp terminal connections. The output blocking voltage is 1200 Vp. The dimensions are W45mm x H58mm x D29mm.
