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-half

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, transceiv-

ers, sensors or other control functions. A patented design incorpo-

rating a custom integrated circuit into a small package (0.55 in

[9.0

]) the BIAS Module provides an immediate “drop-in” solution,

requiring no additional external components.

Actual Size

Bias Power AC/DC power supplies are designed to be

applied in two major categories of applications…

Auxiliary, where the Bias supply is one of two or more sup-

plies and provides power for standby, housekeeping, bias-

ing or other requirements. 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 opti-

mum system performance.

The characteristics of the Vo and Vr outputs are different

and each has application-specific benefits which can pro-

vide 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 over-

loaded and can be shorted indefinitely. The graceful transi-

tion 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 design-

your-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 pro-

tected 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.
