Dual Power Source Transfer Cabinet

Hospitals, data centers, and fire pumps need two power sources. One from the grid, one from a generator. Our Dual Power Source Transfer Cabinet does automatic transfer switching (ATS). We offer CB-class and PC-class. PC-class is more reliable and costs more. We help you choose. The transfer time is adjustable from 0.5 to 2 seconds. For an ICU or a fire pump, every millisecond matters.

We add a mechanical interlock inside every Dual Power Source Transfer Cabinet. This guarantees the two power sources never close at the same time. Even if the control circuit fails, the mechanical lock stops a parallel connection. Safety first. We also add a generator start signal. When utility power fails, the ATS sends a dry contact to the generator. The generator starts automatically. Once the generator voltage is stable, the ATS switches to the backup side.

A hospital in Zhejiang installed our Dual Power Source Transfer Cabinet in their ICU. A typhoon cut the utility power. The ATS switched to the generator in 1.2 seconds. The ICU equipment did not stop. No patient was affected. The hospital director called to thank us. We test every unit for at least 50 transfer cycles.
