30V/1A Low Current High Resolution DC Power Supply

Model 1739

MSRP $639 / 3 Yr Warranty
Where to Buy

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
  • Exceptionally low current ripple and noise (<0.4 mArms)
  • 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 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
