1739 - 

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.

Features:

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
