LND-1200 High Precision Six Phase IP67 Protection Tester Secondary Injection Relay for Set Electronic 0.2 Accuracy
LND-1200 High Precision Six Phase IP67 Protection Tester Secondary Injection Relay for Set Electronic 0.2 Accuracy
1. Meet all on-site testing requirements. The microcomputer relay protection tester has a standard six phase current, six phase voltage output, current of 30A/phase, and voltage of 125V/phase. The parallel connection of six phase current can reach 180A. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protection devices, especially for transformer differential protection and backup automatic switching devices, making the testing more convenient and perfect. 2. Various technical indicators meet the DL/T624-1997 "Technical Conditions for Microcomputer Type Test Devices for Relay Protection" standard issued by the Ministry of Electric Power. 3. The classic Windows XP operating interface is user-friendly and easy to operate; A high-performance embedded industrial control computer and an 8.4-inch TFT true color display screen with a resolution of 800x600 can provide rich and intuitive information, including the current working status of the device and various help information. 4. The native Windows XP system comes with a recovery function to avoid system crashes caused by illegal shutdowns or incorrect operations. 5. Equipped with an ultra-thin industrial keyboard and an optical mouse, it can perform various operations through the keyboard or mouse just like operating a regular PC. 6. The main control board adopts a DSP+FPGA structure, with 16 bit DAC output. It can generate high-density sine waves of 2000 points per week for the fundamental wave, greatly improving the quality of the waveform and improving the accuracy of the tester. 7. The power amplifier adopts a high fidelity linear power amplifier, which ensures both the accuracy of small currents and the stability of large currents 8. This microcomputer relay protection tester uses a USB interface to communicate directly with a PC without any adapter cables, making it easy to use.9. Can be connected to a laptop (optional) for operation. Laptops and industrial computers use the same set of software, without the need to relearn operating methods. 10. Equipped with an independent dedicated DC auxiliary voltage source output, with output voltages of 110V (1A) and 220V (0.6A) respectively, for use in relays or protection devices that require DC working power. 11. With software self calibration function, it avoids the need to open the chassis and adjust the potentiometer to calibrate accuracy, greatly improving the stability of accuracy.
