Powerstax’ medical PSUs meet latest approvals

Powerstax’ Medistax range of power supplies for medical applications has now been approved to the latest version of IEC 60601-1:2005, 3rd Edition. This is in addition to the existing approval to the 2nd Edition and ensures full medical approval is maintained during the transition period from 2nd to 3rd editions.

The Medistax family of power supplies is available in two power ranges, 200-750W and 400-1450W, providing a modular and configurable power solution in an extremely compact 1U high (40mm) package with up to 12 isolated outputs in either a 4 or 6 slot chassis. Typical applications for the include medical imaging equipment, dialysis systems, clinical diagnostic systems and medical lasers.
Employing an plug-and-play architecture, the Medistax units combine feature-laden front-end power units combined with slide-in output converter modules. Powerstax says this allows the configuration of a custom power solution in ‘less than 5 minutes’. All possible configurations carry full safety agency approvals and are CE marked. High efficiencies of over 90% reduce system thermal load and a 15W/in³ power density provides a compact and versatile power solution with less than 300µA leakage current and 4000VAC isolation.
Other standard features include standard output voltages over the range 1.5V to 58V, all outputs are fully floating allowing outputs to be configured in series or parallel to provide custom outputs, 5V bias standby voltage, ultra-high efficiency up to 90% reducing system heat dissipation, visual LED indicators and individual output control signals. A universal 85-264VAC input range is standard as is over voltage protection and the full load operating temperature range is from -20 to +70°C.
The updated medical approvals for the Powerstax Medistax power supply includes  ANSI/AAMI ES60601-1:2005, Medical electrical equipment– Part 1, General requirements for basic safety and essential performance, CAN/CSA-C22.2 No. 60601-1:08 Medical electrical equipment,  Part 1: General requirements for basic safety and essential performance,  IEC60601-1:2005 Medical electrical equipment– Part 1: General requirements for basic safety and essential performance.
