1747

Data Sheet Dual Range DC Power Supplies Models 1737 & 1747 B&K Precision’s models 1737 and 1747 are general purpose dual range DC power sources. These power supplies can output higher voltage at a lower current range or more current at a lower voltage range. Two 4-digit LED displays continuously monitor the output voltage and current. The power supplies can be operated locally from the front panel or remotely through the RS-232 interface. The 1737 and 1747 both exhibit excellent regulation and low ripple characteristics. Their mechanical configuration conserves bench space and allows for easy portability. Features and Benefits These power supplies are well-suited for a wide variety of electrical and electronics applications in service shops, engineering labs, production, school laboratories, and home use. ■ Low ripple and noise ■ Excellent regulation ■ Constant voltage (CV) and constant current ■ Two 4-digit LED displays provide Output Ratings/Model 1737 Voltage 0-3 A (0-30 V range) 0-2 A (0-60 V range) Dual range to accommodate applications requiring either a higher voltage or a higher current (CC) mode operation good visibility in bright or low light 1747 0 - 60 V Current ■ 0-10 A (0-35 V range) 0-5 A (0-60 V range) ■ LED indication for CV and CC modes ■ Automatic recall of last settings on power up ■ RS-232 interface ■ Front panel emulation software available for download 1737 Operating Range 1747 Operating Range Range 1 Range 2 Range 1 Range 2 60 Voltage (V) Voltage (V) 60 30 0 1 2 Current (A) Technical data subject to change © B&K Precision Corp. 2012 3 35 0 5 10 Current (A) w w w.bk prec ision.c om ■ Isolated output ■ Overload protection ■ Reverse polarity protection Dual Range DC Power Supplies Models 1737 & 1747 Front Panels Rear Panels Two Power Supplies in One Fanless heatsink design for quiet bench operation The 1737 and 1747's unique dual range feature offers the best of both worlds by supplying two different ranges with either higher voltage or more current depending on your application, avoiding the higher cost of buying more power than necessary. 17 37 RS-232 interface enables the instrument to be remotely controlled via PC Bright, 4-digit LED displays Voltage and current coarse and fine control Output terminals 17 47 LED indicators for constant voltage and constant current modes Software Application Bright, 4-digit LED displays Utilize B&K Precision’s application software, available for download at www.bkprecision.com.
