Profile:

HMJBC-903 relay protection tester meet all test requirements on site.The instrument has standard four phase voltage and three-phase current output. It can test not only various traditional relays and protection devices, but also various modern microcomputer protections, especially for transformer differential protection and standby automatic switching device. The test is more convenient and perfect.

Features:

  1. Classic Windows XP operation interface, friendly man-machine interface,
  2. This Windows XP system has its own recovery function to avoid system crash caused by illegal shutdown or misoperation.
  3. Equipped with ultra-thin industrial keyboard and photoelectric mouse,
  4. The main control board adopts DSP + FPGA structure and 16 bit DAC output.
  5. The high fidelity linear power amplifier ensures the accuracy of small current and the stability of large current.
  6. USB interface is used to communicate with PC directly without any connecting line, so it is convenient to use.
  7. can be connected to laptop (optional) to run.Laptops and industrial computers use the same set of software.
  8. It has the function of GPS synchronization test.
  9. Equipped with independent dedicated DC auxiliary voltage source output, the output voltage is 110V (1a), 220V (0.6A).It can be used for relays or protection devices that need DC power supply.
  10. It has the function of software self calibration, which avoids opening the case to calibrate the accuracy by adjusting the potentiometer, thus greatly improving the stability of accuracy.
