Product Details

LCD Single Phase Digital Energy Meter Panel/Voltmeter with Multifunction


1. Product Overview:


Measurement: three phase voltage, threephase current, active power, reactive power, power factor, frequency, active energy, reactive energy.
Calculation: positive and negative active energy, inductive and capacitive reactive power.
Display: LCD display with STN blue screen, wide viewing angle, high quality and high definition.
Communication: RS485 communication, and MODBUS-RTU protocol.
Output: two-way power pulse output, four-way switch output, and four-way analog output.
Input: four-way switch input.

LCD multi-functional network meter can highly precisely measure the general power parameters in three-phase grid system: three-phase voltage, three phase current, active power, reactive power, power factor, line frequency, active energy,
reactive energy. It also has the function of communication interface, electrical pulse output, four-way switch input,
four-way switch output, and four-way analog output. With the communication protocols, it is able to give LED display
on-site and remote-site communications. The LCD multi-functional meter is convenient to install, easy to wire,
and simple to maintain.It has few projects and can be set input parameters as field programmed. And it can communicate with different PLC and industrial computers in the netwok

2. Product Functions:

Measurement: ammeter, voltmeter, single-phase active and reactive power meter, three-phase active and reactive power meter and power factor meter. Display: four LED digital display of 9999. Maximum input: voltmeter: 600V, voltage transformer is required when the AC voltage is over 600V; ammeter: 5A, current transformers is required when the AC current is over 5A. DC ammeter: 5A, built-in shunts of 75mv, 60mv and 50mv are required when the DC current is over 5A. Uses: suitable for measuring the parameters in ammeter, voltmeter, single-phase active and reactive power meter, three-phase active and reactive power meter and power factor meter in the industries of electric power grids, automation, substation automation, power distribution automation, intelligent building, and the enterprise's internal system. To be matched by the client: RS485 communications, two-way switch output, two-way switch input, and one way analog output. Time aging: all the products have been time-aged, so that it can stably work in a long-term to reduce the impact of external environment on the meter, offering users a satisfactory product.

4. Installation Precautions:


Installing the meter with the power is forbidden!!

The meters should be installed indoor and protected with the special metering box; and the mounting plate should be fixed tightly on the anti-flaming and there shall be no harmful substance such as dust, salt spray causing the corrosion in the air.

The connection process should in accord with the wiring diagram printed inside the meter cover and the leads should be made of copper to connect the bottom of the meter terminal that tightened with the screws to protect the meter from being damaged by the loss contact.

5. Transportation & Storage:

The goods should be free from violent collision when delivery and being sealed off, and as per the rules of GB/T13384-2008 General Technical Conditions Of Mechanical and Electronic Products Packaging to transport and store them.

Stack the inventory and storage on the shelves under the condition of original package and its height should be no more than 8 levels.

The place to store the goods should be clean and the temperature should be in the range of -40℃ and 70℃ as well as less than 95% of relative humidity; And the hazardous substance that would lead to the corrosion is not allowed to exist in the air .
