Class 0.05 Single Phase Program Control Testing Source
Introduction
This device adopts programmable FPGA, high speed high precision D/A converter, DDS technology, can regulate frequency, amplitude, phase signal source, and amplify signal power. It’s with high precision standards of voltage, current, power, electric energy inside, by analog closed loop feedback and digital PID control it can output voltage, current, frequency, phase, and trace the set parameters automatically over a long period of time. It is combination of standard power frequency indicating meter and energy meter, can be used to calibrate a lot kinds of electrical instruments. And It can connect with PC to realize automatic calibration and total management of testing data.
