INTRODUCTION
The
B+K Precision
Model 1715 DC Power Supply is a high quality,
general purpose de power source. It provides 0-60 volts de output,
adjustable with both coarse and fine voltage controls for precise setta­
bility. The current output is 0-2 amps, adjustable with both coarse and
fine current controls. Two large LED meters continuously monitor the
output voltage and current. The VOLTAGE meter is green, while the
CURRENT meter is red.
The Model 1715 exhibits excellent regulation and low ripple charac­
teristics. 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.
This instrument 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 variations
cause the current to reach the preset limit, the unit then regulates output
3
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 a 0-to-120 volt
power source, or two supplies may be connected in parallel, with suitable
balancing resistors, for up to twice the output current.
This power supply is well suited for a wide variety of electrical and
electronics applications, including service shops, engineering labs, pro­
duction testing, school laboratories, and home use by hobbyists.
