Product Introduction

This professional relay protection tester fully meets on-site test requirements, featuring standard four-phase voltage and three-phase current output. It is versatile for testing traditional relays, protection devices, and modern microcomputer protection systems, with specialized convenience for transformer differential protection and standby automatic switching device tests.All technical indicators comply with the power industry standard DL/T624-1997 "Technical Conditions for Microcomputer-based Test Device of Relay Protection". It adopts a classic Windows XP interface with a built-in recovery function to avoid system crashes from illegal shutdowns or misoperations, paired with a high-performance embedded industrial control computer and an 8.4-inch 800×600 TFT true color display that provides intuitive real-time working status and help information.Equipped with an ultra-thin industrial keyboard and optical mouse, it operates like a regular PC. The main control board uses a DSP+FPGA architecture with 16-bit DAC output, generating 2000 high-density sine waves per fundamental wave cycle to enhance waveform quality and testing accuracy. A high-fidelity linear power amplifier ensures precision for small currents and stability for large currents, while a USB interface enables direct PC communication without additional cables for easy use.
