The BK Precision 1630 DC Power Supply is a high quality, general purpose dc power source. The 1630 provides 0-30 volts dc output, adjustable with both coarse and fine controls for precise settability. The current output is 0-3 amps. Two current ranges, HI and LO, provide excellent current stability and meter resolution. Two large panel-mounted meters continuously monitor the output voltage and current.
The 1630 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.
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 present. 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 operations at the preset value.
Reverse polarity protection prevents accidental damage of the power supply from improper connection to an external voltage, 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-60 volt power source, or two supplies may be connected in parallel, with suitable balancing resistors, for up to twice the output current.
The 1630 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.
