Front End Power System Is Hot-Swappable

Consisting of up to three 1000W hot-swap modules in a 2U high rack-mount style, the TMN Series power system front ends provides up to 3000W at 24, 28 or 48 vdc for distributed power systems. The unit can be operated as either a 3000W non-redundant or 2000W redundant power system. The output voltage is adjustable over a ±10% range. An optional 3U high rack holds up to five hot-swap modules in a vertical configuration and provides up to 5000W output. The modules feature 5.5W/in.³ power density, integral output isolation diode, two cooling fans, and a hi-rel, hot-plug connector. Other features include ac power good and dc power good LEDs together with the output voltage adjustment potentiometer on the front panel. Control and monitoring signals include ac power good, dc power good, current monitor, remote output adjust, remote enable, module present, and remote sensing. The modules also have zero minimum load requirement, constant power-limiting overload protection and an independent 5V, 100 mA auxiliary output for powering external control circuits. In OEM quantities, pricing is as low as $461 each for the hot-swap modules and $339 each for the three-position, 2U mating rack.
