B&K Precision 1739 - Datasheet - Manual

The B&K Precision model 1739 is a high
resolution, low current DC power source with
excellent load regulation and low noise
characteristics. 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 RS-232 interface. The mechanical
configuration conserves bench space and allows
for easy portability.

Low Current Precision Design
The 1739 is a low current precision power supply designed especially for small current applications
that require a clean and precise source. Using a MOSFET circuit design and high quality components
with very low temperature coefficients, the power supply is extremely stable and capable of outputting
current as low as 1 mA with a 100 uA settable resolution. The power supply is also implemented with
a high performance AC line filter to minimize noise on the power line before rectification, allowing for
very low ripple and noise at the output.
This power supply is well suited for electrical and
electronics applications requiring precise levels of
low current, including 4-20 mA current loop
testing, calibration, or basic IC testing.
