Product Overview

LF3600Manufacturer of microcomputer relay protection testerIt has a standard six phase current and six phase voltage output simultaneously, with a current of 30A/phase and a voltage of 125V/phase. Six phase current parallel connection can reach 180A, meeting all on-site testing requirements. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential protection and backup automatic switching devices. The testing is more convenient, and various technical indicators meet the standards of DL/T624-1997 "Technical Conditions for Microcomputer Test Devices for Relay Protection" issued by the Ministry of Electric Power.

Manufacturer of microcomputer relay protection testerFeatures

1. Single machine independent operation, built-in high-performance industrial computer, clock speed 1.8GHz dual core, 2G memory, 16GB hard disk, running Windows XP operating system.

2. The domestic industry is the first to adopt imported brushed stainless steel panels, acrylic numeric keyboards, and touch mice, overcoming the disadvantages of inflexible and easily damaged operation of trackball mice. It also uses an 8.4-inch TFT true color display touch screen with a resolution of 800 × 600, making the overall operation of the single machine convenient and durable.

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

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

5. It uses a USB interface to communicate directly with the PC without any adapter cables, making it convenient to use.

6. Can be connected to a laptop to run. Laptops and industrial computers use the same software, so there is no need to relearn the operating methods.

7. Equipped with an independent dedicated DC auxiliary voltage source output, with output voltages of 110V (1A) and 220V (0.6A) respectively. To be used for relays or protective devices that require DC working power supply.

8. It has software self calibration function, which avoids the need to open the chassis and adjust the potentiometer to calibrate accuracy, greatly improving the stability of accuracy.
