XL-9200XL-9200 DC energy meter calibration device is the latest standard voltage and current source designed and developed by Shenzhen Xinglong Technology Co., Ltd. In response to the current market needs for DC energy meter calibration, it follows the national standards for DC energy meters and adopts the latest technology. The main components are all imported industrial grade devices, which can support large current signals of 0~200ADC, with an accuracy level better than 0.05%, 0~1000V DC voltage output, an accuracy level better than 0.02%, and 0~5V DC voltage analog shunt. The device output has an accuracy level of 0.2% and supports the voltage and current output ripple superposition function. It can be used for dummy load verification of DC energy meters, ripple interference tests, or as a separate voltage standard source, current standard source, and power standard source. , the device has passed the test of Shenzhen Institute of Metrology.
The device uses an 800×600 LCD display with a clear and simple interface, easy operation and good visual effects. The core module uses 32-bit high-speed DSP combined with adaptive Lagrangian interpolation algorithm to eliminate hardware non-synchronization error of DC ripple. Waveform quantization uses 32-bit dual modulation output technology to ensure high output accuracy. The outputs are protected against overcurrent and overheating, making them safe and reliable.
