Yuanping Three-phase AC/DC Standard Power Source
The three-phase AC standard power source, also known as the mobile three-phase energy meter calibration device, adopts an integrated structure of meter and source, full digital closed-loop standard source technology, using embedded systems, large-screen TFT color LCD and touch screen, CPLD chips, high-precision A/D and D/A converters, and a series of advanced components. It is small in size and light in weight, and can be widely used in the electric energy metering industry, electrical laboratories, and other related departments.
The TH-3S three-phase energy meter calibration device complies with the following standards and verification regulations:
"Verification Equipment for Electricity Meters" GB/T 11150-2001
"Verification Equipment for AC Electricity Meters" JJG597-2005
"Electronic AC Electricity Meters" JJG596-2012
"Electromechanical AC Electricity Meters" JJG307-2006
It has the following characteristics:
? Adopts touch screen control panel plus membrane keys, with large information display, simple and convenient to use.
? Built-in high-grade standard electricity meter, and uses it as the standard for digital closed-loop feedback. Voltage, current, frequency, phase, active power, reactive power, apparent power, power factor, and other parameters can all be used as standards.
? Has multiple protection functions: current limiting protection, amplifier protection, voltage short-circuit protection, current open-circuit protection, amplifier thermal protection, etc.
? Intelligent gear: within the allowable output range of the instrument, users can arbitrarily set the rated voltage and current gears for three-phase voltage and current. The test points and adjustment fineness of voltage and current refer to the rated gear values set by the user, which is convenient for operation.
? Rich test points for voltage, current, and phase, easy to operate.
? Can calibrate various active and reactive energy meters.
? RS232 serial port, open communication protocol, convenient for computer control and software upgrades.
