DDSU5881-C single-phase rail type electric energy meter (with RS-485 communication interface 2P)

Product Overview:

summary:

DDSU5881-C DIN rail mounted single-phase electronic active energy meter is a newly developed single-phase two-wire active energy meter by our company, which adopts microelectronics technology and specialized large-scale integrated circuits, and applies advanced technologies such as digital sampling processing technology and SMT process. The technical performance of this meter fully complies with the relevant technical requirements of the Level 1 single-phase active energy meter in the IEC 62053-21 international standard, and can directly and accurately measure the consumption of active energy by loads in single-phase AC power grids with a rated frequency of 50Hz or 60Hz. This meter is equipped with a 7-digit LCD display to show 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.

Functional 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 36mm.

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 direction of load current flow, indicated by a separate LED.

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. The standard configuration communication protocol complies with DL/T645-1997 standard. Supports DL/T645-2007 or Modbus RTU protocol
