RECOM Introduces Ultra-Compact 4W AC-DC Power Module

RECOM Power Inc. introduced its new RAC04-family for applications with mounting space restriction and low weight requirement. An efficiency close to 80% guarantees high reliability. To MIL-Standards the MTBF reaches 350.000 hours, or 40 years continuous operation.

The compact product series operates with inputs from 90 to 264Vac at 47 to 440Hz and provides outputs of 3.3, 5, 9, 12, 15 or 24V. The completely encapsulated modules weigh only 26 grams and measure 36.5 x 27.0 x 17.1 mm (LxWxH). They are isolated to 3kVac(4kVac optional), short-circuit protected and are overload and overvoltage protected.

This new series features very low no-load current – in standby-mode only 120mW are drawn – a power dissipation said to be better by a factor of 10 compared to conventional products. All converters feature as a standard "Class B"-Filters to EN55022. These modules can be operated with natural cooling at temperatures between -40 to +70°C, whereby Derating has to be observed.
