YJ85A high stability DC voltage regulatorDetailed product description：

Overview
YJ85A high stability DC voltage regulator is a fully transistorized instrument with good stability and a large output dynamic range. When the voltage load of the power grid changes, the output voltage can maintain high stability. The YJ85A high stability DC voltage regulator is designed in two types: rack mounted and desktop. The rack mounted type is combined with the YJ86A high stability DC current regulator and YS106B power source produced by our factory to form a cabinet type SB861A AC/DC precision power supply, which is used in conjunction with the XF1b AC/DC precision meter calibration device. The desktop can be matched with the XUJ2 type DC meter calibration device, which is used as a power source for measuring DC voltage meters by electrical measurement units, electrical laboratories, and meter production plants. The YJ85A high stability DC voltage regulator has an output voltage of 600V and a maximum output current of 300mA. It can also be used as a dual voltage output or positive and negative power output. For example, in physics experiments such as mass spectrometers and accelerators, to ensure the accuracy of the experiments.
