簡單介紹 STR3030A1 three-phase standard source structure of table source integration, digital closed-loop standard source technology, using the embedded system, big screen TFT color LCD display, CPLD chip
本產品由上海徐吉電氣有限公司精心推薦：
產品特性：
1 adopts touch screen control panel to add the mask button, display information, simple to use convenient.
2 Embedded watt-hour meter high standard power, and as a standard for digital closed loop feedback, voltage, current, frequency, phase and active power, reactive power, apparent power, power factor and so on various parameters can be used as the standard.
3 With multiple protection function: current limiting protection, power protection, voltage protection, short circuit protection, current open power amplifier thermal protection, and other functions.
4 three-phase voltage current loop independent control, each phase voltage and current output parameters can be adjusted separay.
5 Smart gear: within the scope of the instrument allows the output, the user can set arbitrary three-phase voltage current gear their rated voltage, current, voltage and current of the sites, the fineness of adjustment of nominal gear is set by the user reference, easy operation.
test voltage, current, phase, rich, easy to operation.
