Product Overview
This product is a collection module designed for measuring high DC voltage and current in industries such as photovoltaics, wind energy, and new energy. It measures the current, voltage, power, and electrical measurement of DC circuits; The DC voltage can be measured up to 1500V, and the current can be measured using the Hall measurement principle. The RS485 digital interface output enables remote transmission, and the product's Modbus protocol is fully compatible with various configuration software or Modbus (RTU) protocols in PLC devices. Can be applied to photovoltaics, UPS, Computer room monitoring, industrial measurement and other fields.
Product Features
