The new TMN Series power system front ends from Unipower provide up to 3,000 watts at 24, 28 or 48VDC for distributed power systems.
With hot-swap capability, the systems can be operated in 2+1 or 3+1 redundant modes, producing 4500 or 6750W, respectively.
There are five standard models, each factory set to 28, 29, 30, 31 or 32V output.
However, the output for each model can also be adjusted over the range of 26.5 to 33.5V and the modules have a power density of 10.6W/in3, making them 85% efficient.
Other features of these power modules include input power factor correction, Class B EMI input filter, single-wire active current sharing between the modules and an output ORing diode.
Also included are front-panel AC and DC "power good" LEDs together with AC and DC "power good" logic outputs, an inhibit input, remote adjustment, thermal alarm and current monitoring outputs.
