0-35V, 0-10A, Digital DC Power Supply BK Precision 1745A

B&K Precision model 1745A is a 0 to 35V, 0 to 10A DC Power Supply. This power supply has all of the great features and performance you would expect from a B&K Precision power supply. One of these features is the four digit LED disply that allows you to see 10mV and 10mA resolution. Another great feature is the output shorting button that allows the user to short the output terminals to set the current limit.

The B+K Precision Models 1744A & 1745A DC Power Supplies are high quality, general purpose dc power sources. They provide 0-35 volts dc output, adjustable with both coarse and fine voltage controls for precise settability. The current output is 0-10 amps, adjustable with both coarse and fine current controls (model 1745A). Two large LED meters continuously monitor the output voltage and current (model 1745A). The VOLTAGE meter is green, while the CURRENT meter is red (model 1745A). These models exhibit 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. These instruments 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 maximum 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 supplies may be connected in series as a 0-to-70 volt power source, or two supplies may be connected in parallel, with suitable balancing resistors, for up to twice the output current. These power supplies are 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.
