Overview
Dual Channel DC Insulation Monitor
The JY series is a specialized device designed for real-time, online monitoring of insulation resistance in DC floating systems. Featuring two independently controlled channels, it allows for simultaneous monitoring of positive and negative poles without interference, even during DC voltage fluctuations. This robust unit ensures safety in critical infrastructure, such as EV charging piles and photovoltaic systems, by providing continuous resistance and voltage data via RS-485 Modbus communication.
