BIAS 1/2 Watt Power Supply BPS 0.5 Series Data Sheet Single (Vo) or Dual (Vo & Vr) Output BPS 0.5-08-00, -08-33, -08-50 BPS 0.5-14-00, -14-33, -14-50 Actual Size Features The BPS Power Supply Module is an ideal solution for numerous Universal Input (85-265 VAC, 50/60Hz) control applications in lighting, sensing, smart building/home and 3 3 Small Size0.55in 9.0cm power distribution. This low-cost supply provides up to one-half Low no-load input power <30mW watt of output power at 8 or 14 VDC (Vo) and an optional 3.3 or 5 Constant power mode, not current limit VDC (Vr) output for microprocessors, logic, timing circuits, transceiv- 3,000 VAC Isolation ers, sensors or other control functions.

Bias Power AC/DC power supplies are designed to be applied in two major categories of applications Operating Specifications ( 120VAC / 60 Hz / 25C unless otherwise specified) Auxiliary, where the Bias supply is one of two or more sup- plies and provides power for standby, housekeeping, bias- Electrical ing or other requirements. Generally, these supply 3.3V or Input Voltage Range 85 - 265 VAC (50/60Hz) 5.0V requirements from the Vr output. In some cases a small amount of Vo power is used.

Output Vo (Peak) 8 or 14 VDC nom. +/- 5% The characteristics of the Vo and Vr outputs are different Line / Load Regulation Vo (Peak) +/- 1% Po < Pmax and each has application-specific benefits which can pro- vide high value to the system designer. Temperature Regulation Vo (Peak) +/- 2% Po < Pmax 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. This For Vo = 8V, Ir out 53mA max, Io+Ir 63mA* output is best suited to drive mechanical relays, solenoids, Output Vr, 3.3 volt (+/- 5%) For Vo = 14V, Ir out 23mA max, Io+Ir 36mA* SSRs, capacitive loads, indicating lights, LEDs and as a source for isolated DC utility power which may be used For Vo = 8V, Ir out 63mA max, Io+Ir 63mA* Output Vr, 5.0 volt (+/- 5%) directly or post-regulated with either a linear regulator or a For Vo = 14V, Ir out 28mA max, Io+Ir 36mA* DC/DC converter. Vo is self protecting, cannot be over- No-load Consumption 30 mW typical Vin=120 VAC loaded and can be shorted indefinitely. The graceful transi- tion from voltage regulation to constant power along with Isolation 3000 VAC (meets UL / CSA & EN Product Safety) 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 no need to oversize a Bias Power supply.

In addition, Vr is supplied internally by Vo. This Package Size 1.10 x 0.92 x 0.55 inches means that any capacitance added to Vo can increase the (L x W x H) 27.94 x 23.24 x 13.97 mm hold-up time of Vr as well.
