2W Switching Supplies Need No EMI Filtering

Occupying under a cubic inch of space, the BPS-2 series switching power supplies provide single or dual outputs, an 85 to 265 Vac input range, and employ a patented circuit that eliminates line EMI to the point that no input filtering is required. The circuit blocks EMI by isolating the input path for the duration of the conducted noise and maximizes conversion efficiency up to 75%. The 1" x 0.875" x 0.5" units handle wide load variations and specify a no-load power consumption of less than 30 mW. Available with output voltages of 8V, 14V, and 8V/5V, price is under $6 each in small OEM quantities. For more information, contact BIAS POWER LLC, Buffalo Grove, IL. (847) 215-2427.
