DJS5169 (RS485 Communication Output Digital Display Meter) is a new generation of programmable intelligent instrument. The instrument supports DC signal monitoring of two channels voltage and two channels current. It can be widely applied to DC signal equipment such as DC charging pile and DC power supply. Equipped with one channel RS485 communication interface, this instrument supports MODBUS-RTU and DL/T645-2007 communication protocol.
As an advanced intelligent and digital power grid front-end acquisition component, the DC Energy Meter mainly monitors the voltage, current, power, and electronic energy in the electrical circuit in real time. The instrument cluster circuit measures, displays, and communicates in one product. The advantages of this instrument are high measuring accuracy, wide measuring range, good stability, long-term work for free adjustment, programmable parameter setting, etc. It is cost-effective and the function combination is simple and practical.
