AC Single Phase Din Rail Meter

AC Single phase Din Rail meter Manufacturer

Wide range adaptability: It performs well in voltage adaptability, with a common working voltage range of 0.9Un - 1.1Un, and some high-performance models can be expanded to 0.8Un - 1.2Un (Un is the rated voltage, such as the common AC 220V). The current input method is divided into direct input and input through CT (current transformer). Direct input meters can withstand different specifications of current such as 5 (60) A, 5 (80) A, etc.; the rated current of CT input is commonly AC 1.5 (6) A. In the face of overload conditions, direct input meters can instantly withstand 30 times the rated current for half the rated frequency cycle; CT input meters can instantly withstand 20 times the rated current for 0.5 seconds. This allows the meter to operate stably and accurately measure in complex and changeable voltage and current environments, ensuring the reliability of power monitoring.​

Strong anti-interference characteristics: From the hardware level, electronic components with excellent anti-interference performance are selected, and the circuit board is carefully laid out to effectively reduce signal interference between lines. At the same time, a shielding layer is added to greatly reduce the impact of external electromagnetic interference on the meter. In terms of software, an efficient filtering algorithm is built in to effectively identify and remove various types of clutter signals. Through strict EMC (electromagnetic compatibility) testing, the product is optimized by simulating various complex electromagnetic environments, so that the meter has excellent anti-static, lightning protection, and anti-electromagnetic interference capabilities. It can work stably and reliably in places with high electromagnetic interference such as substations and large factories, ensuring that the metering data is not affected by external interference.

AC Single phase Din Rail meter function

Basic measurement and intuitive display: It can accurately measure the forward and reverse active energy, and intuitively present the data through the LCD display. The display is usually 6-digit, 7-digit and other different digits, which can clearly display the active energy value. Some meters also support the display of multiple electrical parameters such as voltage and current, and have a data wheel display function. Users only need to operate simply to view detailed electricity consumption information at any time, and quickly and easily grasp the electricity consumption situation. ​

Multiple communication functions: Most products are equipped with RS485 communication interface, follow DL/T 645-2007, MODBUS-RTU and other common communication protocols, and can be easily connected with host computers, data collectors and other equipment to achieve high-speed data transmission and remote monitoring and management. Some advanced models also support wireless communication, such as NB-IoT, WiFi, etc., which further expands the application scenarios of meters and the flexibility of data transmission.

Pulse output assists meter reading: With passive pulse output function, it can be easily and seamlessly connected with various AMR (automatic meter reading) systems to achieve remote automatic meter reading. This function greatly improves the efficiency and accuracy of meter reading, reduces the workload and errors of manual meter reading, provides efficient meter reading solutions for power departments and property management units, and helps to realize the automation and informatization of power management. ​

Extended functions to improve management: Our AC single-phase DIN rail meters also have a prepayment function. Users use electricity after recharging, which is convenient for electricity fee management and effectively avoids the occurrence of arrears. It supports multi-rate metering and can calculate electricity fees according to electricity prices in different time periods to help users arrange electricity use reasonably and reduce electricity costs. It can perform load monitoring, monitor power load conditions in real time, detect abnormal power use in time, and ensure the safe and stable operation of the power system. Some products also have anti-theft functions, which prevent the occurrence of power theft through advanced technical means and maintain the fairness and security of the power system.
