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.

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.
System Main functions
