B&K Precision Model 1739 DC Power Supply
B&K Precision Model 1739 DC Power Supply is a high resolution, low current DC power source designed for small current applications. The power supply features a MOSFET circuit design and is capable of current output as low as 1mA with a 100µA settable resolution. Output voltage and current are continuously monitored with two 4-digit LED displays. A high-performance AC line filter minimizes noise on the power line before rectification, allowing for very low ripple and noise at the output. This power supply is well suited for electrical and electronics applications requiring precise levels of low current, including 4mA to 20mA current loop testing, calibration, or basic IC testing.
