DTZ217 Three Phase Four Wire Multifunction active Electronic Energy Meter

General Introduction

DTZ217 Three Phase Four Wire Mulifunction Electronic active Energy Meter can measure the import and the export active energy, the inductive and the capacitive reactive energy, and is with TOU function. It has the anti-tamper function, it will alarm in time of detected tamper events, such as current reversal, voltage phase sequence reverse, meter cover open and terminal cover open, bypass, etc.

Display and indication adopts a large screen LCD with abundant graphics and hint text. The displayed contents can be scrolled automatically or by button, and the displayed items can be configured as per the requirements. It is with backlight. Meter can be read during power outage.

Technical specifications

Main functions

1. Metering and measurements: It can measure voltage, current, active power, reactive power, apparent power, power factor, etc. It can measure the import and export active maximum demand, and four quadrant reactive maximum demand. It is with high accuracy. Class 0.2S, Class 0.5S or Class 1.0 for kWh are available.

2. Display and indication: It adopts a large screen LCD with abundant graphics and hint text. The displayed contents can be scrolled automatically or by button, and the displayed items can be configured as per the requirements. It is with backlight. Meter can be read during power outage.

3. TOU: 4 tariffs; Built-in 2 sets of time zone tables and 2 sets of daily period tables, which can be configured as per the requirements. Moreover, the switching time for both 2 sets of time zone tables and 2 sets of daily period tables can be set and achieve the mutual switching. It can set 14 day period tables and 14 week tables and 100 public holidays.

4. Load profile: It can record the data of multi-channel load profile.

5. Anti-Tamper: The meter will alarm in time of detected the tamper events, such as current reversal, voltage phase sequence reverse, meter cover open and terminal cover open, bypass, etc.

6. Event logs: It can separately record latest 10 times events, such as power outage, programming, time correction, meter cover open, disconnection and reconnection, reset of events, reset of meter, etc.

7. Communication interface: The meter has one optical port, one RS485 and one RS232. These three interfaces are independent with each other.
