B& K Precision’s m odels 1 7 3 7 and 1 7 47 are general purpose dual range D C power sources. These power supplies can output higher voltage at a lower current range or m ore current at a lower voltage range. Two 4-digit LED displays continuously m onitor the output voltage and current. The power supplies can be operated locally from the front panel or rem otely through the RS-23 2 interface. Features and Benefits I D ual range to accom m odate applications requiring either a higher voltage or a higher current I Low ripple and noise I Excellent regulation I Constant voltage (CV) and constant current (CC) m ode operation I Two 4-digit LED displays provide good visibility in bright or low light I LED indication for CV and CC m odes I A utom atic recall of last settings on power up I RS-23 2 interface I Front panel em ulation software available for download I Isolated output I O verload protection I Reverse polarity protection D ual Range D C Pow er Supplies M odels 1737 & 1747 D ata Sheet w w w .bkprecision.comTechnical data subject to change © B& K Precision Corp. 2012 The 1 7 3 7 and 1 7 47 both exhibit excellent regulation and low ripple characteristics. Their m echanical configuration conserves bench space and allows for easy portability. These power supplies are well-suited for a wide variety of electrical and electronics applications in service shops, engineering labs, production, school laboratories, and hom e use.
