1、 Introduction to DC Energy Meter Products

The PZ series DC measuring instruments are designed specifically for DC application scenarios such as DC screens, solar power supply systems, and telecommunications base stations. This series of instruments has powerful functions and can accurately measure key parameters such as voltage, current, power, and forward and reverse electrical energy in DC systems.

It has local display function, making it convenient for on-site personnel to directly read data; At the same time, it can also connect with industrial control equipment and computers, easily build measurement and control systems, and achieve centralized management and analysis of data. The instrument is equipped with RS-485 communication interface, using Modbus RTU protocol, supporting analog output, relay alarm output, and switch input/output. Users can flexibly set and control parameters such as transformation ratio, alarm, communication, and switch output through dashboard buttons according to different needs.

Ordering Example:

Specific model: PZ72- DE/C

Technical requirements: Input voltage is DC 0-1000V; Input range 0-2500A (with the help of an external splitter or Hall element, the range can be programmed); The accuracy level reaches 0.5.

Communication protocol: Equipped with RS485 interface, supporting Modbus/RTU protocol and DL/T645-2007 protocol.

Auxiliary power supply: 85-265VAC/DC, 20-60VDC.

Installation steps: This instrument adopts a screen mounted installation method, which is fixed by squeezing the buckles on both sides. The specific operation is as follows:

Select a suitable location on the distribution panel and open an installation hole with the same size as the opening of the installed instrument.

Insert the instrument into the instrument hole of the distribution panel, and then use the buckle to complete the fixed installation.
