Compact 4 W AC-DC converters

3 March 2010 Power Electronics / Power Management

Recom’s new RAC04 family is a range of 4 W AC-DC power modules designed for applications with mounting space restrictions and low weight requirements.

An efficiency close to 80% guarantees high reliability – demonstrated by an MTBF of 350 000 hours, or 40 years continuous operation.

The compact product series operates with inputs from 90 V a.c. to 264 V a.c. at 47 to 440 Hz and provides outputs of 3,3 V, 5 V, 9 V, 12 V, 15 V or 24 V. The completely encapsulated modules weigh only 26 grams and measure 36,5 x 27,0 x 17,1 mm. They are isolated to 3 kV a.c.(4 kV optional), and feature short circuit, overload and over-voltage protection. The devices feature low no-load current – in standby mode only 120 mW are drawn – and all converters feature 'Class B' filters to EN55022 as standard. They can be operated with natural cooling at temperatures between -40°C to +70°C, whereafter derating has to be observed.
