BIAS 2 Watt Power Supply BPSX 2 Series Data Sheet Single (Vo) or Dual (Vo & Vr) output BPSX 2-08-00, -08-33, -08-50 BPSX 2-14-00, -14-33, -14-50 BPSX 2-24-00 Actual Size Features: The BPSX is a revolutionary, micro-sized, drop-in switching power supply module. It contains patented technology with unique features that provide solutions for a wide range of applications, including low power wireless and many other intelligent control devices. The patented SMPS topology is totally different from any other: It's Quiet: Switching is synchronized and occurs only 10% of the time, so there is very little EMI / EMC interference with other circuits. This means no extra filtering or shielding is needed, helping to achieve longer transmission range with more reliable data communication in low power wireless applications. * * * * * * * * Extended Temperature with NO DE-RATING!

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. It's Green: High efficiency with ultra low standby power and very little self generated heat make it ideal for intelligent devices such as smart-sensors, smart-meters, smart-lighting, smart-grid, M2M or IoT , and any other control applications.

This output is best suited as a source for isolated DC utility power, which may be used directly or post-regulated with either a linear regulator or a DC/DC converter. Vo is self protecting, cannot be overloaded and can be shorted indefinitely. So unlike design-yourown, or partially complete modules where significant design margin is required to stay far away from current limit, there is no need to oversize a Bias Power supply. The graceful transition from voltage regulation to constant power along with the wide range of product ratings allows the designer to select a supply tightly matched to the design load. Vr is also a voltage-regulated output and is thermally protected from overload. It has very low output ripple capable of driving elements which require a low-noise, tightly-regulated supply. In addition, Vr is supplied internally by Vo. This means that any capacitance added to Vo can increase the hold-up time of Vr as well. *Note: maximum currents specified for constant voltage range only.
