Half-Brick DC-DC Converter Has 24, 48 Vdc Inputs

Sept. 26, 2014
Powerstax has introduced a new series of advanced DC-DC converter products.

A series of advanced dc-to-dc converter products from Powerstax are housed in industry standard 1/2 brick packages format, with either 24 or 48 Vdc input buses. The members of the H0331 series are highly suited to incorporation within industrial, telecommunications and data networking systems.

With power densities reaching 10.3 W/cm 3 (169 W/in.³), these units are highly effective at maximizing the output power delivered in modern, space constrained systems designs. They are able to provide output levels of  336 W/21 A and their ultra-low leakage inductance magnetics allow power efficiency figures of between 88% and 90%, depending on operating conditions.

The H0331 series' multi-layer single side PCB construction, with aluminum based sink-plate technology, facilitates rapid dissipation of heat. This significantly improves reliability - with an MTBF of 4.1 million hours resulting. Available in both open-frame and fully enclosed options, the series complies with IEC60950-1 and EN 61000 standards. An extensive operational temperature range, covering -50 °C to 110 °C, is supported.
