The product was chosen by NARI-Technology, Nanzi Group! The instrument was specially chosen by China EPRI to AC sampling access network verification. Product overview: DK-51B three-phase electric (power) standard source is designed by a lot of technology such as modern test, DDS waveform synthesis, DSP, CPLD, large-scale integrated power amplifier, original operating system, etc. The product with high integrated, reliable and stability. It is true of testing and checking AC sampling, relay protection, indicating instrument and energy meter, and that is the ideal instrument used for testing and checking electric power products in power system. Main Features: 1. The first in China to integrate system, test and signal generate into a module, high integration, standard output, low fault rate, small volume, light weight, fast response speed, high efficiency, strong function, large output power. 2. Adopt original operating system, starting up show the test image immediately, no need bootstrap, fast response speed, high work efficiency. 3. Voltage, current, power, phase, frequency are all adopt the output of excellent closed-loop system, one-time set point, software adjustment, easy to use. 4. Voltage, current, phase set abundant common experiment point, easy to operate, one-click to complete, convenient and efficient to use. 5. Output of standard harmonic is 2~31 times, processing the output of single and random superimposed multiple harmonic, and can view the output state of harmonic. 6. It can randomly shift phase between three-phase voltage, three-phase current and per phase voltage and current, thus can simulate the output of various power failure also. 7. With the function of multiple alarming and protecting, fault detection automatically, and showing the fault type and position, safe and reliable to use. 8. Equipped with interface and software, the open interface protocol, customers can individually program and control apparatus.
