It has standard four-phase voltage and three-phase current simultaneous output, voltage 125V/phase, current 40A/phase. Three-phase current parallel can reach 120A.
2. All technical indicators fully meet the standard of DL/T624-1997 "Technical Conditions for Microcomputer Test Devices for Relay Protection" issued by the Ministry of Electric Power.
3. Stand-alone operation, built-in high-performance industrial computer, main frequency 300--600MHz, memory 512M, hard disk 4--12G, running Windows XP operating system.
4. In the same industry domestically, it is the first to adopt imported brushed stainless steel panel and stainless steel keyboard, and uses touch mouse, overcoming the disadvantages of trackball mouse being inflexible and easily damaged. It also uses an 8.4-inch TFT true color display with a resolution of 800×600, making the overall operation convenient and durable.
5. The main control board adopts DSP+FPGA structure, 16-bit DAC output, which can generate high-density sine waves of 2000 points per cycle for the fundamental wave, greatly improving waveform quality and test accuracy.
6. The power amplifier adopts high-fidelity linear power amplifier, which ensures both the accuracy of small currents and the stability of large currents.
7. It uses USB interface to directly communicate with PC, no need for any conversion cables, convenient to use.
8. It can be connected to a laptop for operation. The laptop and the industrial computer use the same software, no need to relearn operating methods.
9. It has GPS synchronization test function. The device can be built-in GPS synchronization card (optional) connected to PC via RS232 port, enabling two testers to conduct synchronous adjustment tests in different locations.
10. It is equipped with an independent dedicated DC auxiliary voltage source output, with output voltages of 110V (1A) and 220V (0.6A) respectively, to provide DC working power for relays or protection devices that need it.
11. It has software self-calibration function, avoiding the need to open the chassis to adjust potentiometers for calibration, thus greatly improving the stability of accuracy.
