DC-ATS DC-ATS

DC-ATS

It monitors the status of two independent DC power supply circuits in real time and outputs a stable DC voltage. In the event of a fault in the main supply circuit, the DC-DC converter switches over rapidly to ensure the reliable operation of DC-powered loads and facilitate maintenance.
