AC/DC power supply 1739

regulatedstabilizedwith overload protection

The model 1739 is a high resolution, low current DC power source with 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 uA 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. Low 1 mA settable current limit with 0.1 mA resolution Output on/off button Constant voltage (CV) and constant current (CC) operation Two large, easy-to-read LED displays provide good visibility in bright or low light conditions CV and CC mode indicator Automatic recall of saved voltage and current settings upon power-up RS-232 interface Isolated output Overload and reverse polarity protection Power-on self test
