DTSU866 / DSSU866 Three phase rail type electric energy meter (with RS-485 communication interface 4P)

Overview

The DTS866 DIN rail mounted three-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 technology. 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 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 convenient to set up.

Features

1. It is installed using a 35mm DIN standard rail, which complies with DIN EN 50022 standard, or it can be installed in front of the board. Users can choose between the two installation methods.

2. Width of 7 poles, in compliance with DIN 43880 standard.

3. Adopting a 7-bit LCD display, there are two types of displays: 6+1 bit and 5+2 bit (999999.9kWh, 999999.99kWh).

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. It has 4 LEDs that indicate the phase power status (yellow, green, red), power pulse signal (white), and 1 yellow COM for RS485 communication indication (only with 485 function).

6. The optional RS485 function has RS485 communication function, which can be connected to the RS485 communication network for remote meter reading and centralized management. The standard configuration communication protocol complies with DL/T645-1997 or Modbus RTU standards.
