Powerstax Adds Modular 1U AC-DC Power


New Products Apr 23, 2006 by Jeff Shepard

Powerstax plc has introduced the Multistax range of ultra-low profile ac-dc power supplies. The 1U high, 4 or 6 slot Multistax range has been specifically designed to allow easy and rapid configuration. This is achieved by employing an internal architecture based on simple plug-in power modules that convert the intermediate bus voltage to the specific output voltage required by the end user.

Customers may specify one of three different front-end power units either 700W, 1,000W or 1,200W and the required output modules to meet the their specific application. Powerstax will assemble the system from stock, configure as required and typically ship the final system within 24 hours.

Each Multistax Power Unit can accommodate up to six fully floating power modules of up to 240W output power each. These may be fitted in any combination, provided the overall required output power does not exceed the total power capacity of the front end. The range of eight plug-in output power modules covers output voltages from 1.5 to 58 Vdc and includes single and dual output versions as well as units that can provide up to 50A output current.

These units are rated for full power operation over an operating temperature range of -20°C to +60°C. They are targeted for use with the latest 1U-high rack-mount equipment. The profile of 40.4 mm and a footprint of 260mm × 127mm means that Multistax power supplies have a power density of more than 15W/in³.

Featuring a universal input that accommodates 85 to 264 Vac (47 Hz to 63 Hz) and 120 to 380 Vdc, the product range includes built-in EMI filtering that meets EN55011, EN55022 and FCC level B for conducted and radiated emissions and EN61000-4-x level 3 for immunity to conducted and radiated RFI, electrostatic discharge, fast transients, line surges and voltage dips.

Tim Worley, CEO of Powerstax comments, "this new range of highly configurable power supplies continues our approach to the market of providing application rich, innovative and leading-edge products. We set out to ensure that our customers get the right product for their applications without having to make any compromises."

The Multistax range is available immediately and dependent upon specification, prices start from USD 410 each for quantities of 100 pieces.
