YJ86(A) Type High Stability DC Stable Current SourceDetailed product description：

I. Overview
The YJ86A high stability DC steady current source output current regulation consists of a five step adjustment switch and a fine adjustment potentiometer, making it easy to use. output
A fully transistorized instrument with minimal impact of external circuit load changes on current stability. When the voltage or load of the power grid changes, the output current can maintain high stability. The YJ86A high stability DC stabilizer is designed to be 20A for YJ86A-2. It is combined with YJ85 high stability DC stabilizer and YS37 audio power source to form a cabinet style SB861A AC/DC precision power supply device. Used as a power source for measuring DC current meters by electrical measurement units, electrician laboratories, and meter manufacturers. It can also be used separately by users as a substitute for battery storage.
