Unipower's new UL listed rack is 2U high and holds three Vanguard TVN Series 1000W hot-swap power modules.

The system produces 3000W at 24 or 48V DC in a non-redundant mode or will produce 2000W in a 2+1 redundant mode.

This rack is UL listed in both the USA and Canada.

UL listing means that the complete rack has been tested by UL to its safety standards for an "end product" as found in UL60950.

The rack, which is a standard 19in wide, is completely enclosed.

It has three IEC320 AC inputs, one for each power module.

The module outputs are paralleled in the rack with their current share terminals connected together.

Three switches on the front panel control the three module outputs.

There is also a locking bar to hold the modules in place.

The rear panel has two D-type connectors, one for the DC output and the other for control and monitoring functions which include module present, DC power good and AC power fail for each module.

There are also remote sense terminals and a current share terminal for paralleling two or more racks.
