DIN RAIL KWH Meter Single Phase

DIN RAIL KWH Meter Single Phase uses advanced dedicated energy metering chips and high-precision digital sampling and processing technology to accurately measure the active energy in a single-phase AC power grid with a rated frequency of 50Hz or 60Hz. The common accuracy level is 1.0 or even higher. Products that comply with the IEC62053-21 international standard or GB/T 17215 related national standards can strictly control the measurement error within a very small range under specified conditions to ensure the accuracy of energy measurement.

Single phase Two Wire DIN Rail meter Manufacturer

Diverse displays: usually equipped with an LCD display with 6-digit and 7-digit display digits to choose from, which can display multiple electrical parameters such as active energy, voltage, current, etc., and can also realize data wheel display for easy viewing by users.

Rich functions: With passive pulse output function, it is convenient to connect with various AMR systems to realize remote meter reading; it supports RS485 communication interface, follows DL/T 645-2007, MODBUS-RTU and other communication protocols, and can exchange data with the host computer to realize remote control and centralized management. Some meters also have prepayment, multi-rate metering, load monitoring, anti-theft and other functions.

Is the installation of DIN RAIL KWH Meter Single Phase complicated?

The installation is very simple. The meter can be directly inserted into the rail to complete the installation, saving space. It is suitable for distribution boxes and other scenarios where the meter is centrally installed. In addition, some products also support front-panel installation. The center distance of the installation holes is usually 63mm. The installer can flexibly choose according to the actual installation environment and needs. Generally, people with basic electrical knowledge can quickly complete the installation by referring to the product installation manual.

What key points should be paid attention to during installation?

Before installation, carefully check whether the appearance of the meter is damaged and whether the lead seal is intact. Choose a well-ventilated, dry place without strong electromagnetic interference for installation. Strictly follow the meter wiring diagram for wiring, be sure to use wires of appropriate specifications, and tighten the terminals to prevent safety hazards and measurement errors caused by poor contact. If CT access is used, pay special attention to the correct connection of the transformer ratio and polarity, otherwise it will cause measurement errors.
