LoRaWAN Advanced Single Phase Energy Meter with Predictive Analytics and LCD Screen Real-time Monitor
- Product Overview
DDZY2397 single-phase charge control intelligent electric energy
meter is a fully digital intelligent electric energy meter
developed by our company. Adopt SOC high integration chip. In
addition to the active electric energy metering function, it also
has a variety of functions such as online power display,
intelligent power theft prevention, overload control, remote
centralized meter reading, etc. The data is transmitted to
thecorresponding platform through LoRaWAN/CAT1/Bluetooth wireless
network. It has the characteristics of high precision, low power
consumption and good stability,and can be widely used in the
measurement of single-phase AC power in urban, rural or factory
enterprises.
- Highlights:
1. Metering of positive and negative active electric energy. The
electric energy shall be accumulated and stored separately for
tip,peak, flat, valley and other periods and the total electric
energy. It can store and display various electric quantities in the
last 12 months.
2. It can measure, store and display the current voltage, current,
power, power factor, frequency and other operating parameters and
status of the electric energy meter. It has overload protection
function.
3. There are two sets of rates (tip, peak, flat and valley) and
time periods that can be programmed at will, and another set of
rates and time periods can be used at the set time point. At least
2 time zones can be set for each set of rate periods throughout the
year.
At least 14 time periods can be set within 24 hours; The minimum
interval between periods is 15 minutes. The time period can be set
across zero points..
4. It has the functions of event recording such as zero clearing,
programming, timing, power failure, switching on and switching off.
5. Remote power off and transmission function: send power off
command through RS485 and other communication interfaces to cut off
the user's load circuit. Or send the power transmission command to
connect the user load circuit.

Installation
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as possible. Special instrument box protection shall be used for outdoor installation. The installation bottom plate shall be fixed on the wall with strong fire resistance and not easy to vibration. There must be no corrosive gases in the surrounding air where the meter is installed. Avoid dust, salt spray, etc.
When using the electricity meter, the wiring must be conducted strictly according to the wiring diagram in the tail cover of the meter. It is recommended to use copper wire for the lead connected to the terminal seat. The screws of the fixed lead in the terminal seat should be tightened to avoid burning the electricity meter due to bad contact and heating.
