Information
                                    The B & K-Predsion Model 1660 Triple Output DC Power supply
is a high quality, general purpose dc power source. It
provides two supplies with a 0-30 volt dc output and one
with a 4-6.5 volt dc output. The 0-30 V supplies are
adjustable with both coarse and fine voltage controls for
precise settability and are capable of current output of 0-2
amps. The 4-6.5 V supply has a current output of 0-5 amps,
allowing it to handle extensive digital logic circuitry. Two
large panel-mounted LED meter displays can monitor either
the output current or output voltage of each supply.
The two 0-30 volt supplies can be operated independently or
in one of two tracking modes. In the series tracking mode,
the Slave supply tracks the voltage of the Master supply.
Maximum current setting of the two supplies can still be set
independently when in the series tracking operating mode. In
the series tracking mode the Master and Slave supplies are
connected in series, allowing a single output of 0-60 V at
up to 2 amps. In the parallel tracking mode, the two
supplies are connected together in parallel, allowing a
single 0-30 V output at up to 4 amps.
Both 0-30 volt supplies 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 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.
The 4-6.5 V supply is ideal for powering digital logic
circuitry. The 0-5 amp capacity
allows the supply to be used for large circuits. Built-in
overload protection automatically limits to current output
to a maximum of 5 amps. An indicator lights when the supply
is overloaded.
The Model 1660 exhibits excellent regulation and low ripple
characteristics. The circuit design incorporates a
pre-regulator, which greatly reduces internal power
dissipation at low output voltages.
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.
Additionally, the two 0-30 volt supplies can be used as a
"split supply" with two positive voltages and a common
negative, two negative voltages and a common positive, or
one positive, one negative, and a common. All of these
configurations can be used with either matching (tracking)
or differing (independent) voltages.
The features and versatility of the unit, especially the
triple output and tracking features, make it an ideal
general purpose Power supply for engineering lab
applications. It can serve as a single or multivoltage power
source, including the bias supply, for breadboard and
prototype circuits and equipment. It can provide single or
simultaneously varying voltages for circuit evaluation. It
can provide tracking (+) and (-} voltages for evaluating
differential amplifiers. It may be used as a battery
eliminator, or to power individual circuit boards or cards
while removed from the system. Its output can be evaluated
while powering a breadboard or prototype circuit to
determine the circuit's Power supply requirements. Its
laboratory quality specifications will meet most engineering
laboratory requirements.
The same features that make the Model 1660 a good choice for
an engineering lab also
make it a good choice for most other solid state electronic
applications. These applications include service shops;
industrial production testing of components, assemblies, and
complete equipment; for school laboratories, and home use by
electronic hobbyists.
