AC/DC Switching Supplies Offer Improved EMC Performance
Wed, 09/10/2008 - 8:33am
The EFM series of ultra-miniature open frame modular switching power supplies has been expanded for EMC noise compliance to EN55022, Class B. The new additions provide an economical power solution and are pinout and size compatible with more costly encapsulated modules. All models accept universal input from 90-264 VAC while eleven models provide output power of 30 W with single, dual, and triple outputs from 5 VDC to 48 VDC. All models contain overvoltage and short circuit protection circuitry, and internal input filtering. The unit's space-saving dimensions are as small as 3.41" L × 2.36" W × 0.93" H.
