Redundant 54 V supply for EdgePower

This redundant power supply delivers 54 V DC at 72 W for Ubiquiti EdgePower systems. It fits rack or cabinet mounts and accepts 120 V AC or 230 V AC input. Designed for EP-R6 routers and EP-S16 switches needing backup power.

72 W output at 54 V DC

The single figure that decides fit is the 72 W output at 54 V DC. Only devices rated for this exact voltage and power envelope should use this module. Mismatched voltage or higher draw will prevent operation.

Passive cooling in normal use

The unit runs without active fans, so it adds no audible noise to the rack. Heat is dissipated through the metal enclosure during standard loads. Power draw from the wall matches the 72 W output plus conversion losses.

Questions about this item

What does the 72 W output mean for a running router or switch?

The unit delivers up to 72 W at 54 V DC, providing backup power to keep compatible EdgePower devices operating during a primary supply failure.

Which AC inputs does the supply accept and what limits them?

It operates from 120 V AC or 230 V AC mains; the 72 W output ceiling is the practical limit regardless of input voltage.
