Brief Description
Each rectifier provides 80A @ 110V (70A Load + 10A Battery Charging). Two rectifiers operate in N+1 redundancy mode using 415VAC 3-phase UPS input. In case one rectifier fails, the other continues supplying the full rated 80A. Faulty modules are auto-isolated and hot-swappable, allowing replacement without shutdown. Input and output distribution is handled through a Distribution Box, with redundant diode paralleling of the rectifiers.
