BIAS Power Supply Module BPW 4 Series Data Sheet Single (Vo) or Dual (Vo & Vr) output BPW 4-08-00, -08-33, -08-50 BPW 4-14-00, -14-33, -14-50 BPW 4-24-00 The BPW 4 Power Supply Module is an ideal solution for numerous control applications in lighting, sensing, smart building and power distribution where operation from 277VAC mains is required. This low-cost supply provides up to four watts of output power at 8, 14 and 24 VDC (Vo) and optional 3.3 and 5.0 VDC (Vr) output for microprocessors, logic, timing circuits, transceivers, sensors or other control functions. Incorporating a custom integrated circuit into a small package (2.45 in3 [40.1 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. 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.

Both Vr and Vo supplies are often utilized for optimum system performance. Output Vr, 5.0 volt (+/- 5%) Earth Leakage @ 120 VAC Features 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.
