BIAS 1 Watt Power Supply BPWX 1 Series Data Sheet Single (Vo) or Dual (Vo & Vr) output BPWX 1-08-00, -08-33, -08-50 BPWX 1-14-00, -14-33, -14-50 Actual Size The BPWX Power Supply Module is an ideal solution for numerous Features control applications in lighting, sensing and other applications where Universal Input (90-308 VAC, 50/60Hz) 3 3 operation from 277VAC mains and extended temperature range is Small Size0.55in 9.0cm required. This low-cost supply provides up to one watt of output Low no-load input power <30mW power at 8 or 14 VDC (Vo) and an optional 3.3 or 5 VDC (Vr) output Constant power mode, not current limit for microprocessors, logic, timing circuits, transceivers, sensors or 3000 VAC Isolation other control functions. A patented design incorporating a custom Up to 75% efficiency 3 3 integrated circuit into a small package (0.55 in 9.0 cm ) the BIAS EN 55022, Class B FCC Part 15, Class B Module provides an immediate drop-in solution, requiring no addi- Meets UL/CSA and EN Product Safety Require- tional external components.

Ripple Vo ( 120 Hz) 1.00 V p:p Vo is a voltage-regulated output which has a constant ( 100 kHz) 0.25 V p:p power mode instead of a conventional current limit.

Vo is self protecting, cannot be over- loaded and can be shorted indefinitely. The graceful transi- 3000 VAC (meets UL / CSA & Isolation EN Product Safety) tion from voltage regulation to constant power along with the wide range of product ratings, allows the designer to Earth Leakage 120 VAC < 10 uA select a supply tightly matched to the design load. There is Short Circuit Protection Continuous, Pin 0.6 w Vin = 120 VAC no need to oversize a Bias Power supply. Unlike design- your-own, or partially complete modules where significant Reliability 25 C, MIL HDBK-217F > 500 Khr MTBF design margin is required, to stay far away from current Thermal limit, Biass constant power alternative requires no such o over-specing. Operating Temperature -40 to +85 C Operating Relative Humidity 0 95%, non-condensing Vr is also a voltage-regulated output and is thermally pro- o tected from overload.
