Product Introduction

Our company adopts microelectronic technology and specialized large-scale integrated circuits, and applies digital sampling and processing technology to install single-phase electronic active energy meters with guide rail installationSMTA single-phase two-wire active energy meter newly developed using advanced technologies such as technology. The technical performance of this table fully complies withIEC 62053-21In international standards1The relevant technical requirements for single-phase active energy meters are that they can directly and accurately measure the rated frequency50Hzor60HzThe consumption of active electrical energy by loads in a single-phase AC power grid. This table is composed of7bitLCDThe monitor displays functional battery levels and has the characteristics of good reliability, small size, light weight, beautiful appearance, and easy installation. Widely applicable and convenient to set up supporting facilities.

Features:

1. 35mm DIN standard rail installation, in compliance with DIN EN 50022 standard, or front panel installation (with installation hole center distance of 63mm), two installation methods can be freely selected by the user.

2. Width 75mm.

3. 7-digit LCD display, standard configuration 6+1-bit (999999.9kWh) display, optional 5+2-digit display.

4. The standard configuration includes passive power pulse output (with polarity), and passive remote power pulse output (without polarity) can be selected for easy connection with various AMR systems, in compliance with IEC 62053-31 and DIN 43864 standards.

5. Three LEDs respectively indicate the power status (green) and power pulse signal (red), with yellow indicating RS485 communication.

6. The standard configuration does not detect the direction of load current flow, and can choose to automatically detect the load current flowDirection, and byA separate LED indicator.

7. Unidirectional measurement of single-phase two-wire active energy consumption, independent of the direction of load current flow, in accordance with IEC 62053-21 standard.

8. Standard configuration S-type wiring (bottom in, top out), for direct access use, with options for CT access and PT&CT access.

9. The standard configuration includes a short terminal cover, and an extended terminal cover can be selected to protect electrical safety.

10. It has RS485 communication function and can be connected to RS485 communication network for remote meter reading and centralized management. It comes with standard communication protocol and optional communication protocol (MODBUS-RTU or DL/T645 protocol).
