DC POWER SUPPLY
Информация
The B & K-Preclsion Model 1611 DC Power supply is a high
quality general purpose dc power source. The Power supply
provides 0-50 volts dc output, adjustable with both coarse
and fine controls for precise settability. The current
output of the Model 1611 is 0-2 amps. Two current ranges, HI
and LO, provide excellent current settability and meter
resolution. Two large panel-mounted meters continuously
monitor the output voltage and current.
The Power supply exhibits excellent regulation and low
ripple characteristics. The circuit design incorporates a
preregulator, 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.
The 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 current rather than output voltage. Current limits
are adjustable from 0% 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-100 volt power source,
or two supplies may be connected in parallel, with suitable
balancing resistors, for up to twice the output current.
The Power supply is 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.
0-50 VOLTS
Continuously variable over 0-to-50 volt range with coarse
and fine controls.
0-2 AMPS
0-to-2 amps available. Rated for continuous duty at full
output current.
LABORATORY QUALITY
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
HI-LO switch selects full output (0-2 A), or one quarter
output (0-0.5 A). LO range improves current settability and
meter resolution at lower current values. Switch
simultaneously selects range of adjustment and corresponding
meter scale.
BUILT-IN METERING
Two large, easy-to-read meters continuously monitor output
voltage and current.
LED INDICATORS
Act as pilot light and identify mode of operation.
PRE-REGULATOR
Limits internal dissipation for higher reliability.
ISOLATED OUTPUT
Either polarity may be floated or grounded.
OVERLOAD PROTECTION
Fully adjustable current limiting (from 0% to 100% of
maximum output current) protects circuit under test and the
power supply.
REVERSE POLARITY PROTECTION
Prevents damage to Power supply from external voltage of
reverse polarity.
STYLING
Modern functional styling. Configuration conserves bench
space and aids portability. Logical, convenient layout of
controls.
HOOK-UP CABLES
Supplied with red and black hook-up leads.
