LoRaWAN Single Phase IoT Wireless Electricity Meter DDZY2397
DDZY2397 single-phase charge control intelligent electric energy meter adopts dedicated large-scale integrated circuit. Apply digital sampling processing technology and SMT technology. It has the characteristics of less peripheral components, simple structure, high reliability, low power consumption, long service life, etc. In addition to the active power metering function, there are many other functions, such as online power display, one-in-two-out dual-control, one-in-two-out three-control and load identification, intelligent anti-theft, overload control, remote centralized meter reading through LoRaWAN/NB-IoT/Cat. 1/Bluetooth wireless network. It can be used to control the power consumption of students or staff apartments. Under the normal operation of air conditioning and other equipment, it can effectively reduce the hidden danger of electricity safety and reduce the waste of electricity.
1. Double circuit independent measurement of positive and negative
active electric energy. The total, main and secondary circuit
active electric energy can be set. The electric energy shall be
accumulated and stored separately for the electric energy and total
electric energy at the tip, peak, flat, valley and other periods.
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. 3. Current and power limiting function by time: It has two sets of
time limiting meters by time. It can automatically switch according
to the switching time of two sets of time limit tables. Each set of
timesharing time limit table supports up to 10 timesharing
settings. When the current/power is in overrun use and exceeds the
overrun use time, switch off and power off. It can be recovered
automatically when the time after power failure reaches the power
recovery time. 4. Fixed power time limit function: when the ammeter is within a
certain power fluctuation range for a long time and exceeds the
fixed power threshold, it will be switched off after reaching the
fixed power and can be used for a long time. Switch on after
reaching the set power supply recovery delay after switching on. 5. Sudden change power limit function: when the power increase
value of the ammeter exceeds the power sudden change threshold
value during the sudden change period, the switch will be opened.
Switch on after reaching the set power supply recovery delay after
switching on. 6. 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. 7. It has such freezing functions as instantaneous freezing,
regular freezing, daily freezing, agreed freezing, and hourly
freezing. 8. It has the functions of event recording such as zero clearing,
programming, timing, power failure, switching on and switching off. 9. 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. 10. Active upload/two-way transparent transmission function:
actively transmit data to the corresponding platform through
LoRaWAN wireless network. The default interval is 4 hours
(settable). 11. Comply with the national standard GB/T17215.321-2008/2021. The
communication protocol conforms to DL/T645-2007 .
Ammeters must be transported and stored under the original packaging conditions. Products shall not be severely impacted during transportation and unpacking, and shall be transported and stored according to GB / T 25480-2010 Basic Environmental Conditions for Instrument Transportation and Storage and Test Methods as stipulated in 2010. The products should be stored in the warehouse and placed on the platform frame. The stacking height shall not exceed five layers. No corrosive gases shall be present in the stored environment.
If the user complies with the transportation, storage and
installation operation specifications, and the lead seal of the
manufacturer is still complete.If there is a quality problem, our
company is responsible for free repair or replacement within 18
months from the date of delivery the electricity meter. |
