Constant Current

Htap htuk ai constant current system hpe lata na matu, bungli galaw ai lam, kam hpa mai ai lam, yawng manu jahpu hpe dawdan ya ai shada da matut mahkai ai lam law law hpe jep joi ra na re. Engineer ni gaw application a masat da ai lam ni hpe hkan sa ai shaloi, shingjawng hkat ai ra kadawn ai lam ni hpe rap ra hkra galaw ra ai.

Ya na Rating: Madung masat da ai lam gaw, pru wa ai current atsam re. Load a nominal ra ai lam hte bung ai (sh) loi mi jan ai ya aten na rating hpe lata la u. Oversizing gaw component hkam sharang lu na matu margin jaw ya nna htawm hpang na load jat wa ai raitim manu grau law ai hte n-gun n law ai load hpe shayawm ya lu ai. Undersizing gaw grai law hkra pat kau ai (sh) asak hpe kadun shangun ai.

Voltage n-gun: Shapraw ai voltage range gaw load a shawng na voltage hkrat ai hte wiring ninghkap ai lam hpa hpe mung hkap la ra ai. LED lang na matu, series LED yawng a shawng lam voltage yawng hpe sawn la nna, 10-20% margin hpe jat bang u. Voltage range n law ai gaw, mawdaw gau ai wa hpe current hpring tup n lu jaw ai, grai law ai range gaw n ra ai atsam hpe jahten kau ya ai.

N-gun marai: Grau kaja ai atsam gaw bungli galaw ai manu hte nbung hpe hkangzing ra ai lam ni hpe shayawm ya lu ai. Switching regulator ni gaw 85-95% n-gun hpe lu la nna, linear regulator ni a matu gaw 40-70% n-gun lu la ai. Raitim, galai ai converter ni gaw manu grau law nna, wan nsen hpe shapraw ya ai. Katsi katsang bungli galaw ra ai application ni gaw linear design ni kaw na n-gun yawm ai hpe tara shang shabyin ya lu ai.

Dimming galaw ra ai lam ni: Application hta nhtoi htoi ai hpe hkang ra ai rai yang, dimming hte htuk manu ai hpe jep yu u. Masha law malawng lang ai nhtoi hpe shayawm ai ladat ni hta 0-10V analog, PWM, DALI, hte nhtoi hpe shayawm ai ladat ni lawm ai. Constant current driver yawng gaw dimming amyu yawng hpe madi shadaw ya ai n re. Dimming range (minimum kaw nna maximum du hkra nhtoi htoi ai) hte n-gun n rawng ai lam hpe jep yu u.

grup yin masa: Bungli galaw ai shaloi, nbung katsi ai, nbung katsi ai, nbung katsi ai, shock ra ai lam ni hpe myit yu u. Shinggan de jung da ai shaloi, nbung n-gun n-hkap la lu ai shingdu shingwang (IP65 or IP67 ratings) ni ra ai. Industrial makau grup yin ni hta, nhprang wan, hka lim ai, shing nrai, tsi mawan ni hpe hkam sharang lu na matu, conformal coating (sh) laksan packaging ra na re.

Masat masa hte hkan sa ai lam: Galoi mung n-gun rawng ai mawdaw gau ai ni gaw, yaw shada ai gat lawk a matu, htap htuk ai shimlam masat masa (UL, CE, TÜV) hte wan n-gun hte htuk manu ai masat masa ni hpe gun hpai ai hpe jep yu u. Tsi hpaji hte seng nna IEC 60601 masat masa galaw ra ai. Nkau installation ni gaw, n-gun atsam madang (sh) power factor hpe sharai la na matu, masat da ai masa ni hpe hkan sa ra ai.

Kam mai ai lam hte garan gachyan ai lam: Hten za ai lam ni a lapran na aten (MTBF) gaw, daw ni a myit ru myit tsang lam hpe sawk sagawn ai hta madung tawn nna myit mada da ai kam hpa mai ai lam hpe madun ai. Grau galu ai garan gachyan ai lam gaw, galaw shapraw ai wa gaw, arung arai ngang grin ai lam hpe kam hpa ai lam hpe tsun dan ai. Hkrun lam hkawm na matu yak hkak ai (sh) galai na matu manu kaba ai installation ni a matu, kam hpa mai ai lam gaw, kaga arung arai ni hta grau nna manu jahpu jaw ai lam hpe tara shang shabyin ya lu ai.

Constant current gaw amperage hpe n galai shai ai sha tawn da ya nna, voltage gaw load hpe ninghkap ai hte maren shai hkat nga ai. N galai shai ai n-gun gaw, n-gun hte n-gun (P=V × I) a n-gun hpe, masat da ai wattage de, parameter lahkawng yan hpe dynamic hku gram lajang ai hku nna, hkang zing ya ai. Constant power mode gaw, solar panel simulation zawn re ai application ni hte, n-gun yawng hpe jaw ya ai lam gaw, laksan voltage (sh) current manu ni hta grau ahkyak ai, bungli galaw ai lam nkau mi a matu akyu rawng nga ai.

Strip light zawn re ai n-gun n law ai LED application ni hta LED hpawng hta bang da ai ya aten -limiting resistor ni hte n galai shai ai voltage supply ni hpe lang chye ma ai. Ndai ladat gaw LED product hpe constant voltage bungli galaw na matu laksan galaw da ai shaloi bungli galaw ai. Raitim, n-gun kaba ai-n-gun kaba ai langai hkrai LED ni gaw, n-gun n-htum mat hkra, n-gun n-htum ai sha, nhtoi htoi tu ai hte asak galu ai hpe hkam la lu na matu, ap nawng da ai n-htum n-wai ai current driver ni ra nga ai.

Series LED ni a jahpan hpe langai hkrai a shawng lam voltage hte garan nna, LED yawng a shawng lam voltage hpe sawn la u. Wiring hkrat sum ai hte hkam sharang ai lam ni a matu 10-20% voltage margin hpe jat bang u. LED a n-gun rating hpe parallel string ni a jahpan hte garan nna, n-gun yawng ra ai hpe chye lu na re.
