1.\tMeets all the requirement of field tests. This tester with standard 4 phase voltage, 3 phase current output, voltage 125V/phase, current 40A/phase, 3 phases in parallel can up to 120A. Digital Signal Processor Microcomputer. Not only test the traditional relays and protectors, but also test the modern micro computer replays, special for transformer differential protection and transfer equipment.
2.\tClassic Windows 7 operating interface, friendly man-machine interface, easy and fast to operate; High-performance embedded industrial control computer and 8.4 inch resolution of 800 × 600 TFT true color display which provides rich visual information, includes the current working condition and all kinds of help information.
3.\tIntegrated metal industrial keyboard and touch screen, which can complete various operations through multifunctional metal keys and touch screen..
4.\tThe main control board is DSP + FPGA architecture, 16 bit DAC output, generates high - density sine wave 2000 points each circle to fundamental wave, which greatly improve the wave quality and the accuracy of the test instrument.
5.\tUsing high-fidelity linear amplifier. Both to ensure the accuracy of a low current, but also guarantee the stability of the high current.
6.\tPerfect self-protection function, adopt rationally designed heat dissipation structure, and have reliable and perfect various protection measures and power soft start, with a certain degree of fault self-diagnosis and blocking function
7.\tUSB directly connect with PC, without any adapter cable, easy to use.
8.\tWith a separate DC auxiliary voltage source, output voltage 110V(1A),220V(0.6A), provides relays or protective devices which require DC power.
9.\tThe software with self calibrating function, which avoid to calibrate accuracy by adjusting relays after open the case, greatly improve the stability of the accuracy.
