Single Phase Smart hmanga pawisa pek hmasakna Meter

 

Single phase smart prepayment meter hi IEC international standard nena inmil Class 1.0 active energy metering device a ni a, single-phase two-wire power system atan a tha hle. Energy metering, prepayment management, load control, leh event logging ang chi function hrang hrang inzawmkhawmin, he meter hian optical port leh RF module hmanga inbiakpawhna a pui a, LCD screen hmangin key data a entir bawk. Power supply enterprise te tan chuan electric enkawlna tha tak neih theihna tura duhthlanna tha tak a ni.

1. Energy Metering hman dan tur

Active Energy: Import, export, leh absolute active energy tehna a pui (Absolute energy=|Import energy| + |Export energy|). Data chu LCD-ah a lang thei a, software hmangin chhiar theih a ni bawk.

Reactive Energy (Optional): Quadrant pali-a teh a ni a, import leh export reactive energy khawlkhawmna a thlawp (Import=|Q1| + |Q2|; Export=|Q3| + |Q4|).

2. Real-time Monitoring leh Statistics

Instantaneous Values: Voltage, current, power factor, frequency, etc. te real-time tehna leh recording, minute 1/minute 60 chhunga average, maximum, leh minimum value statistics te support a ni.

3. Pawisa pek hmasak dan tur ruahmanna

Recharge Function: Digit 20 encrypted TOKEN hmangin recharge la, recharge record dik tak hnuhnung 50 record a ni. Recharge zat, hun leh TOKEN zawhna zawh theihna a support.

Short Code Query: Key data rang taka hmuh theih nan code bik (eg, total active energy atan 800, credit la awm atan 803) ziak lut rawh.

Emergency Overdraft (Optional): Balance 0 a nih chuan code "811" ziak la, preset overdraft limit enable rawh.

4. Load Control leh Safety Protection

Overload Protection: Second 30 chhung threshold a pelh hnuah relay chu automatic-in a disconnect a, second 30 hnuah reconnection tumna a awm bawk overload 5 hnuah reconnection chu minute 30 chhungin a tikhawtlai.

Anti-fraud Function: Cover hawn, magnetic interference, leh current reversal ang chi anomalies te a hmuchhuak a, second 4-30 hnuah relay a disconnect a, thil thlengte a log bawk.

Event Logging: Power quality, relay control, fraud detection, leh standard events (eg, power on/off, battery hniam) record 100 a dahkhawm a, chutah chuan hun leh thil thleng zat pawh a tel.

5. Display leh Inbiakpawhna

LCD Display: Credit la awm, cumulative energy, instantaneous voltage/current, etc. te entir nan automatic in a scroll a, decimal place 2 precision a nei bawk.

Communication Ports: Optical port (IEC62056-21 nena inmil, baud rate 300-9600bps) leh RF module (CIU nena inbiakpawhna) te a ni.

He single phase smart prepayment meter hi scenario hrang hrangah hman theih a ni a, chu chu chenna hmun, sumdawnna hmun, industry hmun, damdawi in, etc. Prepayment function hian property neitu leh hmangtute tan recharge awlsamna a pe thei hle a, electric recharge-a harsatna awmte chu a chinfel sak thei a ni.

Thilthawnna:A nghawng na tak chu pumpelh rawh;

Dahthatna:Original packaging-ah dah la, temperature -45℃~+70℃, relative humidity awmna hmunah dah rawh<85%, and free of corrosive gases;

Thil chhinchhiah:Product hi fixed-type instrument a ni a, user-adjustable parts a awm lo. Thuneihna tel lo chuan enclosure hi hawng suh.

Meter hi IEC leh a kaihhnawih international standard zawm chunga siam a ni a, metering dik leh stable operation neih theih nan performance leh reliability test khauh tak neih a ni. Technical documentation kimchang leh user support pek a ni bawk.
