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.
