INTRODUCTION

The B+K Precision Model 1735A DC Power Supply is a high quality, general purpose dc power source. It provides 0-30 volts dc output, adjustable with both coarse and fine voltage controls for precise settability. The current output is 0-3 amps, adjustable with both coarse and fine current controls. Two large LED meters continuously monitor the output voltage and current. The VOLTAGE meter is green, while the CURRENT meter is red.

The Model 1735A exhibits excellent regulation and low ripple characteristics. The circuit design incorporates a pre-regulator, which greatly reduces internal power dissipation at low output voltages. The styling is both attractive and functional. The mechanical configuration conserves bench space and allows for easy portability.

This instrument 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 maxi mum 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.

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. Two sup plies may be connected in series as a 0-to-60 volt power source, or two supplies may be connected in parallel, with suitable balancing resistors, for up to twice the output current.

This power supply is well suited for a wide variety of electrical and electronics applications, including service shops, engineering labs, production testing, school laboratories, and home use by hobbyists.
