Product Details

1、 Product Name:Three phase four wire electronic typeprepaidelectricity meter, three-phaseprepaidelectricity meterThree phase four wire electric meter, power meter
2、 Specification and model: 10 (40) A 15 (60) A 20 (80) A 30 (100) A 1.5 (6) A
3、 Functional features:
Measurement function:
An electric energy meter can measure positive and negative active energy, and negative energy is accumulated in the positive direction.
Output function:
The electric energy meter adopts a passive isolation type power pulse output interface, and the pulse output waveform is a rectangular wave.
The electric energy meter has the function of outputting electricity pulses, which are indicated by LED light emitting diodes.
Prepaid management function:
The energy meter can be used in conjunction with the PC power sales system to achieve prepaid management functions. The design of the power sales software and energy meter functions strictly follows the GB/T18460-2001 standard and has been mass-produced for a long time. The power sales software and energy meter functions have high stability.
Voltage:
The reference voltage is Un=220VAC, and the operating voltage range is 145VAC~265VAC (it can withstand 24 hours under 420VAC voltage without damaging the energy meter).
4、 Instructions for using an electric energy meter
1. One table, one card: The IC card held by the user cannot be exchanged. In case of loss, a replacement card should be purchased from the power supply department (i.e. the electricity sales office).
2. Preparation for purchasing electricity: Users must insert the IC card into the card slot once to facilitate the return of data from the meter to the computer database.
3 ways to purchase electricity: When selling electricity, insert the IC card into the IC card reader and operate the computer to encrypt the user ID, pre purchased power, capacity limit method, and power limit into the IC card.
4. Electricity card usage: Insert the power purchase card into the card slot. If it is a valid power purchase card, the meter will automatically read the data into the meter. The LCD (LED) display screen will show the following in sequence: purchased electricity (P0=XXXX), total purchased electricity (P=XXXXXX), purchased electricity times (PC=XXXX), alarm electricity (P1=XXXX), credit limit (P2=XXXX), and limited capacity power (FOX=XX: XX). Please store the unplugged card properly.
5 Operation Display: During the operation of the energy meter, the display screen alternately shows the remaining power and total power consumption in the meter.
6. Overcapacity alarm: During the operation of the electric energy meter, if the "alarm indicator light" flashes rapidly, it warns the user that it has exceeded the capacity and reported power consumption; If the user is set to the over capacity power-off limit mode, after 30 seconds of over capacity power consumption, the switch will be turned off for 3 minutes and displayed in a countdown (180 seconds) to restore power supply; If the user inserts the card and responds, the power supply can be immediately restored.
7. Storage limit: If the purchased electricity+remaining electricity>stored electricity (10000 kWh), the purchased electricity will not be read in, and the display will show a "remaining limit" prompt, indicating that the stored electricity in the card is still valid.
8 Warning reminder: When the remaining battery level in the meter is less than twice the "alarm battery level", the "alarm indicator light" will flash (with an interval of 1 second) to remind the user to purchase electricity. At this time, if the user responds by inserting a card, the "alarm indicator light" will flash at an interval of 2 seconds to avoid power failure.
9 Power outage warning: If the user does not respond by inserting the card during the warning reminder, when the remaining power is the user's agreed alarm power (or 10% of the purchased power), the energy meter will trigger a power outage warning and display a "power outage" prompt. At this time, insert the IC card into the card slot once to restore power supply. If the IC card of this meter cannot be found after pulling the switch, you can borrow a neighbor's IC card to insert it and restore power supply.
10 Power purchase reminder: When the remaining power in the meter is less than the "alarm power", the "alarm indicator light" will remain on as a constant reminder.
11 Fault declaration: When the remaining power is displayed as zero or negative, a "trip" prompt will be displayed. If the energy meter continues to operate, the user should immediately purchase electricity and proactively report the situation to the power supply bureau.
Storage of 12 electric cards: Keep away from magnetic fields and do not use sharp objects to scratch, bend, contaminate, or soak. Otherwise, the electric card will not be able to purchase electricity, affecting your normal use
5、 Precautions
The electricity meter has been inspected and qualified before leaving the factory, and sealed with a lead seal before installation and use. If there is no lead seal or it has been stored for too long, relevant departments should be asked to re verify and seal it before installation and use.
The electric meter should be installed vertically and not tilted in a dry and ventilated place. The bottom plate for installing the electric meter should be fixed on a sturdy, fire-resistant, and vibration resistant wall. The height of the electric meter is about 1.8 meters.
Connect the wires according to the circuit diagram, tighten the wiring screws, and secure the connecting plate inside the terminal box..
Before purchasing electricity, users must insert the power card into the card slot once to facilitate sending the data in the meter back to the computer database.
When using, insert the power card into the card holder. If it is a valid card, the meter will automatically read the data into the meter. The data tube will display the original remaining power in the meter (3 seconds) and the total power after stacking (12 seconds). Then, remove the card and store it properly..
If the remaining power is displayed as zero and the meter continues to operate while the overdraft indicator light is on, the user should immediately purchase electricity and proactively report the situation to the power supply department.
