Product Features
1. All technical indicators fully meet the standard of DL/T624-1997 "Technical Conditions for Microcomputer-based Test Equipment for Relay Protection" issued by the Ministry of Electric Power.

2. Stand-alone operation, built-in high-performance industrial computer, main frequency 300--600MHz, memory 512M, hard disk 4--12G, running Windows XP operating system.

3. In the domestic same industry, it first adopts imported brushed stainless steel panel and stainless steel keyboard, and uses touch mouse, overcoming the shortcomings of trackball mouse which is not flexible and easy to damage, and selects 8.4-inch TFT true color display with resolution of 800×600, making the overall operation of the single machine convenient and durable.

4. The main control board adopts DSP+FPGA structure, 16-bit DAC output, which can generate high-density sine wave with 2000 points per cycle for fundamental wave, greatly improving the waveform quality and improving the accuracy of the tester.

5. The power amplifier adopts high-fidelity linear power amplifier, which ensures both the accuracy of small current and the stability of large current.

6. USB interface is used to communicate directly with PC, no need for any conversion cable, convenient to use.

7. Can be connected to laptop for operation. Laptop and industrial computer use the same software, no need to relearn operation methods.

8. Equipped with GPS synchronization test function. The device can be built-in GPS synchronization card (optional) connected to PC via RS232 port to realize synchronous adjustment test between two testers in different places.

9. Equipped with independent dedicated DC auxiliary voltage source output, output voltages are 110V (1A), 220V (0.6A) respectively. It is provided for relays or protection devices that need DC working power supply.

10. With software self-calibration function, avoiding the need to open the chassis to adjust the potentiometer to calibrate accuracy, thus greatly improving the stability of accuracy.
