Product Details

Protection Relay Tester | Multi-Channel 300v/105a Output | Iec 60255 Certified

Product Introduction

RPT-003 adopts modular high-precision linear power amplifier technology and embedded intelligent control system, which can simulate complex fault scenarios such as power grid short circuit, harmonic interference (within 60 times) and frequency fluctuation (0.001Hz~1kHz), and automatically generate ISO standard test reports. The device has built-in multi-channel output module (AC 300V/105A, DC 300V/20A), phase accuracy ±0.05°, and is suitable for full parameter testing of differential relays, reclosing controllers and PLC modules. Remote control is achieved through RJ45 Ethernet or customized software, and efficiency is improved by 30%.
