DSSU5881-C and DTSU5881-C three-phase rail type electric energy meters (with RS-485 communication interface 7P)

summary:

The DTSU5881-C and DSSU5881-C DIN rail mounted three-phase electronic active energy meters are newly developed by our company using microelectronics technology and specialized large-scale integrated circuits, as well as advanced technologies such as digital sampling processing and SMT technology.

The technical performance of this meter fully complies with the relevant technical requirements of the Level 1 three-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 three-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 easily compatible with devices.

Features:

1. 35mm DIN standard rail installation, compliant with DIN EN 50022 standard, or front panel installation（The center distance of the installation hole is 63 mm, and users can choose between two installation methods.

2. Width 125mm.

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

4. Standard configuration includes passive power pulse output (with polarity), and passive remote power pulse output can be selected(Non polarized), easy to connect with various AMR systems, compliant with IEC 62053-31 and DIN 43864Standard.

5. Six LEDs respectively indicate the phase power status (yellow, green, red) and the power pulse signal (white),The yellow COM indicates RS485 communication.

6. The standard configuration includes detecting the direction of load current flow, automatically detecting the direction of load current flow, andIndicated by a separate LED.

7. Unidirectional measurement of three-phase active energy consumption, independent of the direction of load current flow, in compliance with IEC62053-21 standard.

8. Standard configuration S-type wiring (bottom in, top out), for direct connection use, CT can be selectedAccess based usage and PT&CT access based usage.

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

10. Equipped with RS485 communication function, it can be connected to RS485 communication network for remote meter reading and centralized managementThe standard configuration communication protocol supports DL/T645 or Modbus RTU protocols.
