BK Precision Digital Bench Power Supply, 30V, 1A, 1-Output, 30W / 1217534

Power cord, instruction manual, RS232 cable. 3. B ;K Precision Model 1739 Low Current High Resolution DC Power Supply. B ;K Precision model 1739 low current high resolution DC power supply has excellent load regulation and low noise characteristics. 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 mechanical configuration conserves bench space and allows for easy portability. Using a MOSFET circuit design and high quality components with very low temperature coefficients, the power supply is extremely stable and capable of outputting current as low as 1 mA with a 100 μA settable resolution. This power supply was designed for electrical and electronics applications requiring precise levels of low current, including 4-20 mA current loop testing, calibration or basic IC testing. Features and Benefits. Low 1 mA settable current limit with 0.1 mA resolution Output on/off button Low ripple and noise Excellent regulation Constant voltage (CV) and constant current (CC) operation Two large, easy-to-read LED displays provide good visibility in bright or low light LED indication for CV and CC modes Saved programmed values upon power-up RS-232 interface Pre-regulator for limiting internal dissipation for higher reliability Isolated output Overload protection Reverse polarity protection Power-on self test Modern functional configuration conserves bench space and aids portability. Areas of Application. 4-20 mA loop testing Calibration IC testing Service shops Engineering laboratories Production testing School laboratories Home use by hobbyists
