ASCO D03ATS020200FGX0 Power Transfer Switch Panel Control Screen

ASCO D03ATS020200FGX0 is a 200-amp, 240-volt, single-phase automatic power transfer switch (ATS) in ASCO’s Series 300, designed for standby power systems. The unit ships with an integrated Group G controller—featuring a front-panel display that reports source status and the transfer position, so operators can monitor operation at a glance without external panels. It uses open-transition transfer between normal and emergency sources and supports factory-set, user-configurable parameters for voltage and frequency sensing, timing, and control logic. The Group G controller provides an engine-start control interface and a dedicated signal path to trigger generator start, along with RMS voltage sensing on all phases and frequency sensing of the normal source to ensure accurate transfer decisions. An external manual bypass time-delay option on retransfer is included, enabling deliberate override during maintenance or fault conditions. This 2-pole, 200A/240V ATS is appropriate for commercial and light industrial backup power applications where automatic transfer between sources is required for reliability and uptime.
