summary:

The DTSU5881/DSSU5881 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, compliant with DIN EN 50022 standard, or front panel installationThe center distance of the installation holes is 63 mm, and users can choose between two installation methods.

2. Width 125mm.

3. Standard configuration 6-digit (99999.9kWh) stepper motor pulse counter display, selectable7-digit LCD counter display.

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

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

6. Automatically detect the direction of load current flow and indicate (during operation, the short distance electric energy pulse signal refers to...)When shown in green, it represents the opposite direction of current flow.

7. Single directional three element measurement of active energy consumption in three-phase four wire system, regardless of the direction of load current flowCompliant 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, optionalSelect 5+1-bit pulse counter display for CT access and PT&CT access.
