current (CC) operation
■ Independent or series/parallel tracking
mode operation to double voltage or
current
■ Adjustable current limiting
■ Designed to operate continuously at
rated output
■ Short circuit protection, over voltage
protection, reverse polarity protection

B&K Precision’s 1672 and 1673
are quad
display triple output DC power supplies that
provide two variable outputs and one fixed
output. The variable outputs can work
independently, or in series/parallel tracking
mode. Conveniently adjust voltage and
current with independent front panel knobs
and bright quad LED display.
B&K Precision models 1737 and 1747 are
general purpose dual range DC power sour-
ces. These power supplies can output higher
voltage at a lower current range or higher cu-
rrent at a lower voltage range. Two 4-digit
LED displays continuously monitor the output
voltage and current. The power supplies can
be operated locally from the front panel or
remotely through the RS232 interface.
Features & Benefits
■ Low ripple and noise
■ Excellent regulation
■ Constant voltage (CV) and constant
current (CC) operation
■ Two 4-digit LED displays provide good
visibility in bright or low light
■ RS232 interface
■ Automatic recall of last settings on
power up
The B&K Precision model 1739 is a high
resolution, low current DC power source
that exhibits excellent regulation and low
ripple characteristics. This power supply is
well suited for electrical and electronics
applications requiring precise levels of low
current including 4-20 mA current loop
testing and calibration.
Features & Benefits
■ Low current ripple and noise
(<0.4 mArms)
■ Low 1 mA settable current limit with
0.1 mA resolution
■ Output on/off button
■ LED indication for CV and CC modes
■ Automatic recall of saved voltage and
current settings upon power up
■ RS232 interface
■ Power-on self test
