BIAS 1 Watt Power Supply BPS 1 Series Data Sheet Single (Vo) or Dual (Vo & Vr) output BPS 1-08-00, -08-33, -08-50 BPS 1-14-00, -14-33, -14-50 The BPS Power Supply Module is an ideal solution for numerous control applications in lighting, sensing, smart building/home and power distribution. This low-cost supply provides up to one watt of output power at 8 or 14 VDC (Vo) and an optional 3.3 or 5 VDC (Vr) output for microprocessors, logic, timing circuits, transceivers, sensors or other control functions. A patented design incorporating a custom integrated circuit into a small package (0.55 in3 [9.0 cm3]) the BIAS Module provides an immediate “drop-in” solution, requiring no additional external components.

Generally, these supply 3.3V or 5.0V requirements from the Vr output. In some cases a small amount of Vo power is used. Second is as a main or utility supply where Bias is the only supply and provides all power necessary for the product or system. Both Vr and Vo supplies are often utilized for optimum system performance. Short Circuit Protection Package Size (L x W x H) Features Bias Power AC/DC power supplies are designed to be applied in two major categories of applications… Operating Specifications Earth Leakage @ 120 VAC Actual Size The characteristics of the Vo and Vr outputs are different and each has application-specific benefits which can provide high value to the system designer. Vo is a voltage-regulated output which has a constant power mode instead of a conventional current limit. This output is best suited to drive mechanical relays, solenoids, SSRs, capacitive loads, indicating lights, LEDs and 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. 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. There is no need to oversize a Bias Power supply. Unlike designyour-own, or partially complete modules where significant design margin is required, to stay far away from current limit, Bias’s constant power alternative requires no such over-spec’ing. Vr is also a voltage-regulated output and is thermally protected from overload. It has very low output ripple capable of driving microprocessors , logic, transceivers, sensors and other 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. See V-I curve on page 2 for Vo in constant power range.
