Powerstax, specialist provider of highly optimised power sources, has unveiled the Multistax Premium family of configurable switch mode power supplies. Intended for demanding applications in the industrial, communication and medical markets, these units offer ultra-high efficiency levels, reaching up to 92%, and the thermal load they place on systems into which they are incorporated is reduced by more than 50% compared with alternative products currently on the market.
The power density, which attains a value of 16W/in³ (0.86W/cm3), is derived through the combination of advanced, field-proven planar magnetics, surface mount packaging and proprietary low loss transformer technologies.
The Multistax plug-and-play architecture employed comprises feature-rich front-end power units and slide-in output converter modules. These help configuration, with the process of creating an application-optimised, semi-custom power solution generally completed in less than 5 minutes. The new units are offered in 2 different chassis versions; a 4 slot 600W rated version and 6 slot 1200W rated version. Their slots can be populated with multiple power modules in order that the specific voltage and current combination requirements can be met. Their outputs are fully floating, so they can be brought together in either series or parallel (as well as series-to-parallel) arrangements – this level of versatility means that engineers are able to resolve all manner of complex power system design challenges without having to resort to implementing full custom solutions, with their associated expense and time penalties.
“The flexibility that is inherent in this latest power source family allows virtually any conceivable input/output permutation to be realized. It furnishes our customers with a quick and simple to adjust framework on which to base their power system designs, while also benefiting from a very acceptable price tag,” Tim Worley, CEO of Powerstax. “The low loss architecture combats thermal build-up and boosts overall system performance, so that every mW of power potentially available can be utilized to the utmost.”
Supplied in compact 1U high (40mm) package, with up to 12 isolated outputs, there are a total of 11 output module types found within in the Multistax Premium family. This leaves engineers with an almost limitless number of possibilities for configuring the outputs to meet their particular needs. Output voltages can either be set manually (via a potentiometer) or dynamically (using the various control inputs). The Mulitistax Premium family has UL/EN60950-1 (2nd edition) and UL/EN60601 (1 3rd Edition) approvals. An operational temperature range of -40°C to +70°C is supported.
