Actual Size
The BPW 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 one half watt of output power at 8 or
14 VDC (Vo) and an optional 3.3 or 5 VDC (Vr) output for microproc-
essors, logic, timing circuits, transceivers, sensors or other control
functions. A patented design incorporating a custom integrated cir-
cuit into a small package (0.55 in3 [9.0 cm3]) the BIAS Module pro-
vides an immediate “drop-in” solution, requiring no additional exter-
nal components.

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.
