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
• Model 1739 B&K Precision
