Product Introduction

DF type multi-user energy meter is a fully electronic intelligent multi-user energy meter, with a single-chip microcontroller as the core and a fully modular structure. It can simultaneously measure the electricity consumption status of multiple users and independently monitor the electricity consumption status of each user. It displays the accumulated or remaining electricity consumption of each user in a cyclic manner. And it can achieve online and wireless communication management. It can achieve household detection, centralized installation, and centralized management, and fundamentally eliminate various theft and leakage phenomena, reducing many electricity disputes and accidents.

FEATURES

① Independent central processing units: Communication, measurement, and display are efficiently processed by different PIC microcontrollers to ensure orderly data processing;

② Modular structural design: Vertical vertical structure design, strong and weak electrical shielding isolation, avoiding electromagnetic interference between each other;

③ Variable combination metering grouping: Single and three-phase can be set in any combination, and can simultaneously measure and monitor the electricity consumption status of 39 single-phase households or 13 three-phase households;

④ Humanized display interface: dynamically scan and output each household, displaying the current meter number, single-phase and three-phase settings, power consumption or remaining power, current power, and phase loss reminder;

⑤ Stable and flexible communication line: The communication line is connected to a lightning protection module, effectively avoiding damage to equipment caused by surge currents. The communication rate can be flexibly set and can support 485 TCP/IP、 Telephone network GPRS、 Multiple transmission methods such as fiber optics.

Functional classification

Remote transmission type (Y-shaped): It has basic metering functions and can achieve remote automatic meter reading online or manual meter reading on site through handheld infrared terminals.

Control type (K-type): It has control functions such as prepayment and overload protection, greatly improving electricity cost recovery rate and electricity safety. It can be managed using dedicated line communication or RF card communication.

Safe type (Type A): It can achieve malignant load identification, dual circuit, triple circuit and other safety controls through online means. Suitable for apartment users.

Multiple rate (F-type): Different rates can be set for different periods and time periods (four rates, peak and valley), with three methods: non controlled, remote controlled, and prepaid.
