DSSU866 / DTSU866 Three phase rail type electric energy meter (7P)

Overview

The DTS866/DSS866 DIN rail mounted three-phase electronic active energy meter is a three-phase active energy meter developed by our company using advanced technologies such as microelectronics technology and specialized large-scale integrated circuits, digital sampling processing technology, 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 IEC62053-21 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 stepper motor pulse counter or a 7-digit LCD display to display functional power. It has the characteristics of good reliability, small size, light weight, beautiful appearance, and easy installation.

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 125mm.

3. Standard configuration includes a 6-digit (99999.9kWh) stepper motor pulse counter display, with the option to display a 7-digit LCD counter.

4. Equipped with a polarized passive close range power pulse output port that complies with IEC62053-31 and DIN 43864 standards

5. Five LEDs respectively indicate the power status of each phase, as well as the short distance power pulse signal and remote power pulse signal.

6. Automatically detect the direction of load current flow and indicate it (when the power pulse signal at close range indicates green during operation, it represents the opposite direction of current flow).

7. Single directional three element measurement of three-phase four wire active energy consumption, independent of the direction of load current flow, in accordance with IEC62053-21 standard.

8. You can choose to measure three-phase three wire active energy or three-phase four wire active energy.

9. Standard configuration S-type wiring (bottom in, top out), for direct access use, with the option to display 5+1-bit pulse counters, CT access use, and PT&CT access use.
