Overview
The Delta DRR DRR-20N features dual independent DC input and single common output. It has two independent passive DC OK relays for alarms, separately monitoring the fault signals of the two input power supplies. It has an integrated aluminum alloy heat dissipation housing, DIN rail snap-in installation, IP20 protection, and PCB whole board three-layer anti-corrosion coating. It supports 1+1 and N+1 multi-power supply redundant parallel connection. In case of any input power failure, it can automatically seamlessly switch to another power supply without any power interruption.
