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.
