Madung Magam Bungli ni
1. N-gun shadawn ai
Active Energy: Hkam la ai, dut shabra ai, hte tsep kawp active n-gun hpe shadawn ai hpe madi shadaw ya ai (Hkum tsup ai n-gun=|Shaw ai n-gun| + |Shawt ai n-gun|). Data hpe LCD kaw madun mai ai (sh) software hku nna hti mai ai.
Reactive Energy (N ra sharawng ai): Quadrants mali hku shadawn nna, dut shabra ai hte dut shabra ai n-gun atsam hpe shinggyin la lu ai hpe madi shadaw ya ai (Shawt sit ai=|Q1| + |Q2|; Shapraw ai=|Q3| + |Q4|).
2. Tengman- aten hta yu reng ai lam hte jahpan galaw ai lam
Instantaneous Values: Tengman ai-ten shadawn nna, n-gun, n-gun, n-gun n-gun, n-gun n-gun, etc. ni hpe ka matsing da ai, minit 1/minit 60 laman na shadawn shadang, kaba dik, hte kaji dik htum manu jahpan ni hpe madi shadaw ai.
3. Shawng jaw ai gumhpraw hpe hparan ai lam
Recharge galaw ai lam: 20-digit encrypted TOKEN hku nna recharge galaw nna, hpang jahtum na 50 lang na hkrak ai recharge record ni hpe ka matsing da ai. Recharge jahpan, aten, TOKEN ni hpe san ai hpe madi shadaw ya ai.
Code kadun san ai: Key data ni hpe lawan ladan lu la na matu, masat da ai code ni hpe bang u (ga shadawn, 800 gaw yawng active energy a matu, 803 gaw ngam ai credit a matu).
Hkyak hkyak gumhpraw n-gun jat ai (N ra sharawng ai): Balance 0 rai yang, gumhpraw n-gun jat ai shadawn shadang hpe tau hkrau masat da ai "811" ngu ai code hpe bang u.
4. Load hpe hkang lu ai hte shim lum lam hpe makawp maga ai
Overload Protection: Second 30 daram threshold hpe lai ngut ai hpang, relay hpe shi hkrai shi dawm kau ya nna, second 30 na ai hpang bai matut na matu shakut ai; overload galaw ngut ai hpang minit 30 daram bai matut mahkai na matu jahkring kau ai.
Anti-fraud Function: Cover hpaw ai, magnetic shingjawng ai, current nhtang wa ai zawn re ai anomalies ni hpe mu tam nna, second 4-30 na ai hpang relay hpe dawm kau nna, mabyin ni hpe ka matsing da ai.
Event Logging: Power quality, relay hpe hkang ai, hkalem hkalau ai lam hpe mu tam ai, hte masat da ai mabyin masa ni (ga shadawn, power on/off, battery n law ai) ni hpe aten hte byin ai lam ni hpe jahpan 100 hpe shinggyin tawn da ai.
5. Madun ai lam hte matut mahkai ai lam .
LCD Display: Ngam ai credit, shinggyin la lu ai n-gun, kalang ta byin pru wa ai n-gun/n-gun, etc. ni hpe madun na matu, decimal shara 2 hpe hkrak hkrak madun na matu, shi hkum shi scroll galaw ai.
Matut mahkai lam ni: N-gup magap (IEC62056-21 hte maren, baud rate 300-9600bps) hte RF module (CIU hte matut mahkai ai lam ni) ni lawm ai.
Shawk shawn ai
Ndai single phase smart prepayment meter hpe masa amyu myu hta jai lang mai ai, shinggyim masha ni nga ai shara ni, hpaga yumga galaw ai shara ni, hpaga yumga galaw ai shara ni, tsi rung ni zawn re ai ni hta jai lang mai ai.
Htinggaw hte htaw sa ai lam
Htaw wa htaw sa lam:Grai sawng ai hkra machyi ai lam hpe koi ga;
Gunrai tawn da shara:Shawng nnan na shingnip hta tawn da nna, -45℃~+70℃, nbung katsi ai shara hta tawn da u.<85%, and free of corrosive gases;
Matsing ai:Dai arung arai gaw, lang ai wa - gram lajang mai ai daw ni n lawm ai, ngang grin ai-hpan jak re. Ahkaw ahkang n lu ai sha, shingbyi shara hpe hkum hpaw.
Quality hpe kam hpa ai lam
Ndai meter hpe IEC hte seng ai mungkan madang ni hpe hkan sa nna galaw shapraw ai rai nna, hkrak hkrak meter shadawn ai hte ngang grin ai hku bungli galaw lu na matu, grai sawng ai bungli galaw ai lam hte kam hpa mai ai lam ni hpe chyam dinglik ai lam ni hpe galaw ai re. Hpaji masa hte seng ai laika buk ni hpe tup hkrak hte lang ai ni hpe madi shadaw ya ai.
