DC Power Calibration Of 3 Phase Energy Meter , Safe Voltage Current Calibrator

DC Power Calibration Of 3 Phase Energy Meter , Safe Voltage Current Calibrator

1. Main features

The XL-9060 DC energy meter verification device is the latest DC power meter verification series device designed and developed by Shenzhen Xinglong Technology Co., Ltd. In view of the need for DC power meter verification on the market, the national standard of DC energy meter is adopted, and the latest technology is adopted. The main components are imported industrial grade devices, which can support DC current output of 0~60ADC, DC of 0~1000V. Voltage output, 0~5V DC voltage analog shunt output, accuracy grade better than 0.05%. It also supports voltage and current output ripple superposition function, which can be used for virtual load verification of DC energy meter, ripple interference test, or as a separate voltage standard source, current standard source, and power standard source.
The device adopts 800×600 liquid crystal display, the interface is clear and simple, the operation is convenient, and the visual effect is good. Waveform quantization uses 32-bit dual modulation output technology to ensure high output accuracy. The output has overcurrent and overheat protection, which is safe and reliable.

Shenzhen Xinglong Technology Co., Ltd. was established in 2004, is located in the Nanshan District, Shenzhen high tech Industrial Park, is a professional engaged in the Smart Substation detection equipment R & D, production and sales of national key high-tech enterprise (certificate number: GF201244200546). Attention to intelligence (in the field of digital substation testing technology research, from the beginning of 2009 will be gradually introduced various types of testing equipment, including electronic transformer calibrator, digital electric energy meter calibrator (check), with unit testing instrument, and wisdom to substation field testing and acceptance of the project provides the means and tools. Companies actively involved in the development of a number of national standards, to help power companies to solve some of the problems in the field of intelligent substation testing industry technology.

- SYN is a technology started the company, our unremitting pursuit of technology embodied in products of excellent performance, company's substation intelligent test series products has 26 provinces in the country get successful application, and successfully applied to the "China Electric Power Research Institute (EPRI)", "Chinese Academy", "national high voltage metering station" national level institutions.

The company established a complete quality control system and after-sales service system, as of the end of 2014 the company engineering staff has been involved in the testing of more than 100 National Smart substations, for users to solve a lot of technical problems.

Company has won 7 provincial and ministerial science and technology award, the product has laid a good reputation in the industry.

2014 August Xinglong technology successfully in the shares of small and medium-sized enterprises transfer system (the new board) listing (Stock Code: 830924 and become a public company.

Syn can not develop without the support from all sectors of society, we warmly welcome domestic and foreign customers, agents, investors and our sincere cooperation, common development. The future of the company will be with the national system for the transfer of shares in the capital market platform, efforts to technology upgrades and new product research and development, with three to five years to intelligent substation test products to cover all aspects of the smart substation. Strive to become a benchmark for the field of intelligent substation testing business, for the construction and development of China's smart grid to contribute their own diligence and wisdom.
