Data Sheet Dual Range DC Power Supply Model 1737 Features and Benefits Dual range to accommodate applications requiring either a higher voltage or a higher current Low ripple and noise Excellent regulation Constant voltage (CV) and constant current (CC) mode operation Two 4-digit LED displays provide good visibility in bright or low light LED indication for CV and CC modes Automatic recall of last settings on power up B&K Precisions model 1737 is a general The 1737 exhibits excellent regulation and low RS-232 interface purpose dual range DC power source. This ripple characteristics. The mechanical Front panel emulation software available for power supply can output higher voltage at a configuration conserves bench space and allows lower current range or higher current at a lower for easy portability. download voltage range. Two 4-digit LED displays Isolated output continuously monitor the output voltage and This power supply is well-suited for a wide Overload protection current. The power supply can be operated variety of electrical and electronics applications Reverse polarity protection locally from the front panel or remotely through in service shops, engineering labs, production, the RS-232 interface. school laboratories, and home use. 1737 Operating Range Software Application 0 Utilize B&K Precisions application software, available for download at www.bkprecision.com. This software provides a virtual front panel and a Current (A) simple data logging function to store and log data to a text or CSV file.
