Front end fits 7.5kW into 2U of rack space

Unipower's new TRS front-end power module produces up to 2500W of DC power at 24, 28 or 48V.

Unipower's new TRS front-end power module produces up to 2500W of DC power at 24, 28 or 48V.

This hot-swap module can be built into any system or can be integrated by using the companion rack that provides space for up to three units in a standard 19in rack that is only 2U (88mm) high.

The full system can be operated as a 7500W nonredundant front end or as a 5000W 2+1 redundant front end.

The modules have 11W/in3 power density and 85% efficiency.

Important operating features include an internal output ORing diode in each power module, input power factor correction, Class B EMI input filter, single-wire active current sharing between power modules and a +/-10% output voltage adjustment range from the front panel.

There are also front panel AC and DC power good LEDs together with AC and DC power good logic outputs, a remote enable input, remote output adjust, and thermal alarm and current monitoring outputs.

The modules have overload and short-circuit protection, zero minimum load and remote sensing.

Each power module is self-cooled by a ball-bearing fan.
