The DN3000 series online power quality monitoring device (hereinafter referred to as the monitoring device) is an intelligent data acquisition and processing terminal specifically developed to address power quality issues. It is designed to be adaptable to various complex installation scenarios on-site and is capable of round-the-clock, uninterrupted monitoring of AC and DC power quality data. The monitoring device adopts a modular design concept, comprising the DN3000 power quality monitoring intelligent terminal and power quality acquisition modules (including the DN3000-V voltage acquisition module and the DN3000-C current acquisition module). The acquisition modules are responsible for sampling voltage and current signals. These sampled signals are then transmitted to the DN3000 intelligent terminal, which processes the sampled values and handles data storage, preservation, display, and communication. The entire system can be configured in a modular fashion according to the requirements of voltage and current signal modules.
