Programmable DC Power Supply
Models 1785, 1786, 1787 Programmable Power Supplies offer a new level of
“ease-of-use” and programmable functionality in a low-cost solution. Direct key-in
entry makes voltage and current selection fast, accurate and easy. User
programmed outputs allow the operator to preset 99 frequently used voltage and
current settings into memory for easy recall. Preprogram a 10 step output routine
via the keypad or PC interface for automated testing in preproduction, production
or R&D environments. In-case calibration allows for simple, cost-savings,
uninterrupted operation.
■ Nine user-programmable preset outputs
■ Ten step user-programmable output routine
■ In-case calibration
■ Serial interface cable and software included
■ Download upgraded software from www.bkprecision.com
B+K Precision power supplies can be used in a wide variety of applications
such as: Electronics, Manufacturing, Design Labs, Electronic Education and
Battery Charging.

GPIB Programmable Power Supplies
Offering the best cost per watt available to answer virtually any application, you can
select from three versatile models in popular voltage and current ratings. Each
model features excellent reliability (50K hrs. MTBF) and user flexibility. You can
choose voltages to 35VDC, currents to 6A in single and dual output models, and
rest assured you’ll find the quality you have come to expect from B+K.
■ Excellent programming resolution and accuracy
■ Dual output, dual range flexibility meets most needs;
connect in series or parallel for increased voltage or current
capabilities (Models 1780 and 1775)
■ Integral system software makes in-case calibration quick
and accurate
■ Large character LCD display assures fast, “easy-to-read”
