The B+K Precision Model 1710
DC Power Supplies are
high quality, general purpose dc power sources. The two
models are very similar to each other, and both are covered
in this instruction manual. Each of these power supplies
provides 0-30 volts dc output, adjustable with both coarse
and fine controls for precise settability. The current
output of the Model 1710
is 0-1 amp, while Model 1730
amps. Two current ranges, High and Low, provide excellent
current settability and meter resolution. Two large
panel-mounted meters continuously monitor the output voltage
These power supplies exhibit excellent regulation and low
ripple characteristics. The circuit design incorporates a
pre-regulator, which greatly reduces internal power
dissipation at low output voltages. The styling is both
attractive and functional. The mechanical configuration
conserves bench space and allows for easy portability.
These instruments may be used in constant voltage or
constant current applications. The crossover from constant
voltage to constant current modes is smooth and automatic.
LED’s indicate the “CV” (constant voltage) or “CC” (constant
current) mode of operation. In constant voltage
applications, a current limit may be preset. When load
cause the current to reach the preset limit, the unit then
regulates output current rather than output voltage. Current
limits are adjustable from 5% to 100% of maximum. In
constant current applications, the maximum voltage may be
preset. When load variations cause current to drop below the
regulated value, the unit reverts to regulated voltage
operation at the preset value.
Reverse polarity protection prevents accidental damage to
the Power supply
from improper connection to an external
voltage, and current limiting protects the equipment being
powered, as well as the Power supply
The output is isolated from chassis and earth ground, which
permits full flexibility of connections. When needed, the
(+) or (-) polarity may be strapped to ground, or either
polarity may be floated to an external voltage. Two supplies
may be connected in series as a0-to-60 volt power source, or
two supplies may be connected in parallel, with suitable
balancing resistors, for up to twice the output current.
These power supplies are well suited for a wide variety of
electrical and electronics applications, including service
shops, engineering labs, production testing, school
laboratories, and home use by hobbyists.
Continuously variable over 0-to-30 volt range with coarse
and fine controls.
0-1 AMP AND 0-3 AMP VERSIONS
0-to-l amp (1710
, and 0-to-3 amp (1730
, models available.
Each rated for continuous duty at full output current.
Excellent regulation, low ripple.
CONSTANT VOLTAGE OR CONSTANT CURRENT
Provides regulated dc voltage output or regulated dc current
output. Crossover is smooth and automatic.
TWO CURRENT RANGES
High-Low switch selects full output (0-1 A for Model
1710,0-3 A for Model(1730
), or partial output (0-.25 A for
and 0-.5 A for Model(1730
). Low range improves
current settability and meter resolution at lower current
values. Switch simultaneously selects range of adjustment
and corresponding meter scale.
Two large, easy-to-read meters continuously monitor output
voltage and current.
Act as pilot light and identify mode of operation.
Limits internal dissipation for higher reliability.
Either polarity may be floated or grounded.
Fully adjustable current limiting (from 5% to 100% of
maximum output current) protects circuit under test and the
REVERSE POLARITY PROTECTION

Modem functional styling. Configuration conserves bench
space and aids portability. Logical, convenient layout of
