GF6019D1 high precision DC power source is a standard voltage and current source newly designed and developed by GFUVE.
In order to meet the current requirement for verification of DC energy meter in the market, it follows the international standards of DC energy meters, adopts the latest technology, and the main elements of the devices are all industrial-grade, which can support large current signals from 0 to 600 A DC, and the accuracy level is better than 0.05%; 0~1150V DC voltage output, the accuracy level is better than 0.05%; 0~5V DC voltage analog shunt output, the accuracy level is 0.05%, and supports the voltage and current output ripple superposition function, which can be used for the virtual load verification of the DC energy meter, the ripple interference test, or as a separate standard DC voltage source, standard DC current source, and standard DC power source. It can test DC energy meter basic error, starting test, creep test, error of time of day.
The GF6019D1 DC energy meter calibrator adopts a 19-inch color TFT touch LCD screen, with a clear and simple interface, convenient operation and good visual effect. The core module adopts 32-bit high-speed DSP combined with adaptive Lagrangian interpolation algorithm to eliminate the hardware asynchronous error of DC ripple, and the waveform quantization adopts 32-bit dual modulation output technology to ensure high output accuracy. The device output has overload, short circuit and overheating protection, which is safe and reliable.
