Hka htung nhtoi galai shai ai jak lata ai lam: AC12V vs DC12V & Madung myit yu ra ai lam ni
1. Hpa majaw hka htung wan ni hpe hka htung 12v transformer lang ra ai kun?
Swimming pool ni gaw laksan hka lim ai shara ni re. 220V mains wan n-gun hte hkrak sha n-gun jaw ai rai yang, wan n-gun pru mat ai shaloi, wan n-gun grai sawng ai accident byin wa chye ai. Swimming pool 12v transformer gaw, n-gun kaba ai-mains wan n-gun hpe shim lum ai 12V n-gun kaji ai wan n-gun de galai shai ya lu ai majaw, wan n-gun n-gun yawm wa na hpe grai shayawm ya lu nna, mungkan ting na hka htung shimlam madang ni hpe hkan sa lu ai (IEC 60364{-{7}2 zawn re ai). Dai hta n-ga, 12V low-voltage power supply gaw, lamp line ni a matu insulation ra ai lam hta, hka htung kata na hka lim ai makau grup yin a matu grau htap htuk ai, line aging a majaw byin pru wa ai shimlam tsin-yam ni hpe shayawm ya lu ai, hka htung nhtoi htoi ai ladat a core safety component mung rai nga ai.
2. AC12V hte DC12V hka htung 12v transformer ni gaw hpa shai ai kun? Gara hku lata na?
Ndai lahkawng a lapran na madung shai hkat ai lam gaw, pru wa ai n-gun (output current) amyu hte jai lang mai ai mabyin masa ni hta rai nga ai:
AC12V galai shai jak: Alternating current hpe shapraw ya ai. Shi a akyu ni gaw, n-gun dat shapoi ai tsan ai shara (50 metres laman voltage kaji ai) hte manu n law ai majaw, htunghking halogen pyengdin ni hte LED pool pyengdin nkau mi a matu htuk manu ai. Raitim, sadi ra ai lam gaw, AC12V wan n-ga hta n-gun n rawng ai wiring ni nga yang, inductive wan n-gun loi mi naw nga ai majaw, hka n shang ai junction box hte lang ra ai.
DC12V galai shai jak: Direct current hpe shapraw ya ai, dai gaw grau shim ai (AC induction byin wa na hkrit tsang hpa n nga ai). LED pool nhtoi ni a matu madung lang ai amyu rai nna, AC12V system ni hta grau n-gun ja ai nhtoi htoi ai hte 5%-10% n-gun jai lang ai lam yawm ai. Raitim, shapoi ai tsan ai shara gaw kadun ai (meter 30 jan a matu wire diameter kaba ra ai), manu mung loi mi grau law ai.
Laksan lata na hpaji jaw ga: LED hka htung nhtoi ni a matu DC12V transformer hpe grau ra sharawng ai; AC12V transformer hpe htunghking halogen pyengdin ni (sh) hka htung kaba ni (pipeline metre 30 jan galu ai) ni a matu lata mai ai, line insulation makawp maga ai lam hpe mung dai aten hta sha ngang kang hkra galaw ra ai.
3. Hka htung 12v transformer a n-gun hpe gara hku chye lu na kun?
"Total power + redundancy" ngu ai npawt tara hpe hkan sa ra ai: shawng nnan e, hka htung wan yawng a n-gun yawng hpe sawn la ra ai (ga shadawn, 5 20W LED wan n-gun yawng a n-gun yawng gaw 100W re), dai hpang 20%-30% n-gun redundancy hpe tawn da nna, transformer hpe n-gun hpring hpring hte galaw ai majaw, grai katsi ai hte hkra machyi ai lam ni hpe koi gam lu na matu re. Formula gaw: transformer rated power Yawng pyengdin n-gun × 1.2 (sh) 1.3 hta grau kaba ai (sh) maren sha re. Ga shadawn hku nna, wan n-gun yawng 100W hpe la nna, 120W (sh) dai hta jan ai hka htung 12v transformer hpe lata ra ai. Htawm hpang de pyengdin ni hpe jat bang mai ai rai yang, transformer ni hpe ayan galai shai ai lam n byin na matu, jat wa ai hpang na total power hpe madung tawn nna sawn la ra ai.
4. Hka htung 12v transformer hpe lata ai shaloi gara shimlam masat masa ni hte masat masa ni hpe sadi ra ai kun?
Hkamja lam masat masa gaw ahkyak ai: dai hta .IP67 (sh) dai hta jan ai hka n shang lu ai masat da ai(IP68 hpe hka kata de kadun dawk lup mai ai, hka htung grup yin ni a matu grau htap htuk ai),CE masat masa galaw ai(EU madang) shing nrai .UL masat masa(US madang), hte .RoHS masat masa galaw ai(makau grup yin hpe makawp maga ra ai lam ni). Dai hta n-ga, n-gun grai ja ai hpe makawp maga ai, n-gun n-gun n-rawng ai hpe makawp maga ai, n-gun n-rawng ai hpe makawp maga ai magam bungli ni hpe sadi ra ai - line short-circuit galaw ai shaloi (sh) n-gun grai n-gun ja ai shaloi, transformer gaw wan n-gun (sh) jak rung ni hkra machyi ai lam n byin na matu shi hkum nan n-gun hpe dawm kau ya lu ai. Parameters ni a lam hta, shang wa ai wan n-gun gaw, buga na wan n-gun (220V/50Hz or 110V/60Hz) hte bung ra ai, pru wa ai wan n-gun a n-gun n-gun n-gun (sh) ±5% hta n-pu (sh) maren sha rai ra ai, shing nrai, pyengdin a nhtoi htoi tu ai hpe hkam la lu na matu.
5. Swimming pool 12v transformer hpe bang nna gram lajang ai shaloi gara hku sadi maja ra ai kun?
Install galaw ai shaloi sadi maja ra ai lam ni: 1 Hka htung hka ntsa kaw na 50cm jan tsaw ai shara, hka htung hka lim ai shara hte hka pru ai shara kaw na tsan ai shara kaw tawn da ra ai, aten galu-hka kata de n shang hkra; Wiring galaw ai shaloi hka n shang ai terminal hte insulating tape ni hpe lang nna, positive hte negative pole ni hpe hkrak hkra matut mahkai lu na matu (DC12V gaw positive hte negative pole ni hpe garan ginhka ra ai, AC12V gaw garan ginhka ra ai n rai tim, ngang ngang matut mahkai ra ai); Transformer hte pyengdin lapran na line gaw PVC hka n shang hkra galaw da ai pipe rai nna, lup tawn da ai shara hpe anti-corrosion galaw da ra ai.
Hkamja lam hte seng ai shara ni: 1 Transformer ntsa kaw hka hpawk ai hte nhprang arai ni nga ai kun ngu ai hpe shata shagu jep yu nna, aten dep jasan jaseng ra ai; Output voltage gaw ngang grin ai kun, line joint ni gaw quarter shagu n-gun n rawng ai kun ngu ai hpe chyam yu na; Transformer hpe jan a nhtoi (sh) grai n-gun n rawng ai shara hta aten galu tawn da ai hpe koi nna, shi a prat hpe grau galu hkra galaw ra ai.
