This Low no-load input power <30mW low-cost supply provides up to two watts of output power at 8 or 14 Constant power mode, not current limit VDC (Vo) and an optional 3.3 or 5 VDC (Vr) output for logic functions 3000 VAC Isolation such as a microprocessor, logic, timing circuits, transceivers or sen- Up to 75% efficiency sors. A patented design incorporating a custom integrated circuit into 3 3 EN 55022, Class B FCC Part 15, Class B a small package (0.87 in 14.3 cm ) the BIAS Module provides an Meets UL/CSA and EN Product Safety (ITE) immediate drop-in solution, requiring no additional external com- ponents. 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 90-308 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 Vo is a voltage-regulated output which has a constant Ripple Vo ( 120 Hz) 1.00 V p:p power mode instead of a conventional current limit. This ( 100 kHz) 0.25 V p:p output is best suited to drive mechanical relays, solenoids, For Vo = 8V, Ir out 160mA max, Io+Ir 250mA* Output Vr, 3.3 volt (+/- 5%) SSRs, capacitive loads, indicating lights, LEDs and as a For Vo = 14V, Ir out 70mA max, Io+Ir 143mA* source for isolated DC utility power which may be used For Vo = 8V, Ir out 250mA max, Io+Ir 250mA* Output Vr, 5.0 volt (+/- 5%) directly or post-regulated with either a linear regulator or a For Vo = 14V, Ir out 83mA max, Io+Ir 143mA* 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 select a supply tightly matched to the design load. There is Earth Leakage 120 VAC < 10 uA no need to oversize a Bias Power supply.

In addition, Vr is supplied internally by Vo. This Package Size 1.35 x 1.12 x 0.58 inches means that any capacitance added to Vo can increase the (L x W x H) 34.214 x 28.372 x 14.757 mm hold-up time of Vr as well.
