• Hwj chim & Zaus: Sib phim wattage (W) thiab zaus (Hz) rau qhov system yuav tsum tau ua.

• Txhaum Muaj Peev Xwm: Rau cov khoom siv tiv thaiv (xws li, MCBs), xyuas kom meej tias lawv tuaj yeem ua txhaum tam sim no.

3.Kev Nyab Xeeb & Ntawv pov thawj

• Cov ntawv pov thawj: Nrhiav cov cim xws li UL, CE, IEC, lossis CSA kom ua raws li cov qauv kev nyab xeeb.

• Kev ntsuas IP: Rau kev siv sab nraum zoov / kev lag luam, xaiv kev tiv thaiv ingress tsim nyog (piv txwv li, IP65 rau plua plav / dej tsis kam).

• Explosion-Proofing: Yuav tsum muaj nyob rau hauv ib puag ncig txaus ntshai (piv txwv li, cov nroj tsuag tshuaj).

4.Environmental Factors

• Qhov kub thiab txias: Xaiv cov cuab yeej ntsuas rau kev ua haujlwm kub (xws li -20 ° C txog 50 ° C).

• Durability: Xav txog cov khoom siv tiv thaiv corrosion rau cov av noo lossis corrosive ib puag ncig.

5.Kev sib haum xeeb

• Kev sib koom ua ke: Xyuas kom muaj kev sib txuas lus raws tu qauv (piv txwv li, Modbus, Zigbee) thiab cov khoom sib txuas sib txuas nrog cov kab ke uas twb muaj lawm.

• Software: Tshawb xyuas kev sib raug zoo nrog kev tswj hwm lossis lub tsev ntse platforms.

6.Zog Efficiency

• Kev ntsuas ntsuas: Xaiv rau Energy Star lossis cov ntawv ua haujlwm siab kom txo tau cov nqi mus sij hawm ntev.

• Power Factor Kho: Qhov tseem ceeb rau cov khoom siv hauv kev lag luam kom txo qis kev poob.

7.Quality & Brand Reputation

• Chaw tsim tshuaj paus Reliability: Ua ntej lub npe nrov npe nrog cov ntaub ntawv pov thawj.

• Kev tshuaj xyuas/Cov lus pov thawj: Tshawb nrhiav cov neeg siv tswv yim txog kev ua haujlwm ntev thiab kev ua haujlwm.

8.Kev txiav txim siab nqi

• Tus nqi Lifecycle: Sib npaug cov nqi them ua ntej nrog kev saib xyuas, kev txuag hluav taws xob, thiab kev ua neej nyob.

• Warranty & Support: Tshawb xyuas lub sijhawm lav thiab muaj cov khoom seem.

9.Installation & Kho

• Yooj yim ntawm installation: Txiav txim siab seb puas tsim nyog kev txhim kho.

• Kev pabcuam: Modular designs thiab accessible spare qhov chaw yooj yim kho.

10.Txoj Cai Ua Raws Cai

• Local Codes: Ua raws li NEC, IEC, lossis lwm cov lej hluav taws xob hauv cheeb tsam.

• Kev lag luam Standards: Ua raws li IEEE, ANSI, lossis ISO cov lus qhia uas muaj feem xyuam.

11.Yav tom ntej-Cov pov thawj

• Scalability: Xaiv cov kab ke nthuav dav (piv txwv li, modular switchgear).

• Technology Trends: Zam kev siv thev naus laus zis; xav txog IoT-enabled li rau cov tshuab ntse.

12.Cov neeg siv xav tau

• Kev siv tau: Xyuas kom cov interfaces yog cov neeg siv-phooj ywg, tshwj xeeb tshaj yog rau cov neeg siv tsis siv neeg.

• Ergonomics: Tsim kom yooj yim ntawm kev ua haujlwm hauv qhov chaw npaj.

13.Cov ntaub ntawv & Txhawb nqa

• Phau Ntawv Qhia/Cov Lus Qhia: Txheeb xyuas qhov muaj tseeb ntawm kev teeb tsa / cov lus qhia ua haujlwm.

• Kev pab txhawb nqa: Xyuas kom cov chaw tsim khoom lossis cov neeg muag khoom siv tau.

14.Lub cev & kev txwv kev ua haujlwm

• Qhov chaw txwv: Txheeb xyuas qhov ntev thiab qhov yuav tsum tau ua rau mounting.

• Load Capacity: Rau cov cables, xyuas kom lawv tuav cov load yam tsis muaj hluav taws xob ntau dhau.

• Kev tiv thaiv Surge: suav nrog SPDs hauv thaj chaw uas muaj qhov hloov pauv voltage.

•
