The BK Precision 1743B DC Power Supply is a high quality general purpose DC power source. The power supply provides 0-35 volts DC output, adjustable with both coarse and fine controls for precise settability. The BK 1743B current output is 0-6 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 1743B power supply exhibits excellent regulation and low ripple characteristeics. The circuit design incorporates a pre-regulator, which greatly reduces internal power dissipation at low output voltages. The styling is both attractive and functional.
