BIAS 1/2 Watt Power Supply BPSX 0.5 Series Data Sheet Single (Vo) or Dual (Vo & Vr) Output BPSX 0.5-08-00, -08-33, -08-50 Actual Size BPSX 0.5-14-00, -14-33, -14-50 Features: The BPSX is a revolutionary, micro -sized, drop-in switching power supply Extended Temperature with NO DE-RATING module. It contains patented technology with unique features that (-40 to +85C ) provide solutions for a wide range of applications, including low power Universal Input (85-265 VAC, 50/60Hz) wireless and many other intelligent control devices. The patented SMPS 3 3 Small Size0.55in 9.0cm topology is totally different from any other: Low no-load input power <30mW It s Quiet: Switching is synchronized and occurs only 10% of the time, so Constant power mode (not current limit) there is very little EMI / EMC interference with other circuits. This means no 3000 VAC Isolation extra filtering or shielding is needed, helping to achieve longer transmission EN 55022, Class B FCC Part 15, Class B range with more reliable data communication in low power wireless Meets UL/CSA and EN Product Safety (ITE) applications. It s Powerful: No power de-rating across the full wide temperature range. Bias Power AC/DC power supplies are available with two No current limit design margin needed when selecting a module. Charge different types of outputs to fit your applications large super caps faster than any regular SMPS with twice the power rating. The characteristics of the main (Vo) and auxiliary (Vr) outputs It s Green: High efficiency with ultra low standby power and very little self are different and each has application -specific benefits which generated heat make it ideal for intelligent devices such as smart-sensors, can provide high value to the system designer: smart-meters, smart-lighting, smart -grid, M2M or IoT , and any other control Vo is a voltage-regulated output which has a constant power applications. mode instead of a conventional current limit. This output is best suited as a source for isolated DC utility power, which may Operating Specicatifi ons be used directly or post-regulated with either a linear regulator ( 120VAC / 60 Hz / 25C unless otherwise specified) or a DC/DC converter. Vo is self protecnti g, cannot be over- loaded and can be shorted indefinitely. So unlike design-your- Electrical own, or partially complete modules where significant design Input Voltage Range 85 - 265 VAC (50/60Hz) margin is required to stay far away from current limit, there is Input Surge Withstand 308V, < 30 sec no need to oversize a Bias Power supply.
