RDQH Series (ATS)

The RDQH automatic transfer switch is designed for AC 50Hz power systems with a rated operational voltage of 380V and a rated operational current ranging from 10A to 1600A. It enables automatic circuit transfer between two power supplies as required.

This product provides protection against overload, short-circuit, and under-voltage conditions, and also incorporates fire protection, dual-circuit isolation, and output signal generation functions.
