Cintangiriro y'icyifuzo:

Ku ya 25 Kamena 2021, urubuga rwemewe rwa UL rwashyize ahagaragara icyifuzo giherutse kuvugururwa kurwego rwa UL2054. Gusaba ibitekerezo bikomeza kugeza ku ya 19 Nyakanga 2021. Ibikurikirasni ingingo 6 zahinduwe muri iki cyifuzo:

1. Kwinjizamo ibisabwa muri rusange kumiterere yinsinga na terefone: kubika insinga bigomba kuba byujuje ibisabwa na UL 758;
2. Ivugurura ritandukanye kubisanzwe: cyane cyane gukosora nabi, kuvugurura ibipimo byavuzwe;
3. Kwiyongera kubisabwa kugirango bisuzumweness: guhanagura ikizamini hamwe namazi hamwe namashanyarazi;
4. Kongera uburyo bwo gucunga ibice nibizunguruka hamwe numurimo umwe wo kurinda mugupima amashanyarazi: Niba ari abirikimweIbigizeor imirongo ikorahamwekurinda bateri, mugihe usuzumye ikosa rimwe, ibice bibiri cyangwa imizunguruko bigomba gukosorwa icyarimwe.
5. Kwerekana ikizamini gito cyo gutanga amashanyaraziasbidashoboka: niba ikizamini gito cyo gutanga amashanyarazi mugice cya 13 cyurwego rusanzwe cyakozwe bizagenwa ukurikije ibyo uwabikoze asabwa.
6. Guhindura ingingo ya 9.11-ikizamini kigufi cyumuzunguruko: igipimo cyumwimerere nugukoresha 16AWG (1.3mm2) umuringa wambaye ubusa; igitekerezo cyo guhindura:twe arwanya hanze yumuzunguruko mugufiigomba kuba80 ± 20mΩ insinga z'umuringa zambaye ubusa.

Influence y'icyifuzo ku gishushanyo cya batiri:

Ingingo ya 4 yaicyifuzoirashobora kugira ingaruka nyinshi mubishushanyo bya batiri: iyo igitekerezo cyo guhindura kibi ku makosa yo kurinda no kuzenguruka byemejwe, mugihe uburinzi bukozwe binyuze mumuzingo ibiri cyangwa ibice bimwe, ikindi gikoresho cyo kurinda gikeneye kongerwaho kukoumwimererebakeneye gukosorwa. Kurugero, mugupima ibirenze, niba ari bibirikimweMOSFETs zikoreshwa mukurinda amafaranga arenze urugero zigomba gukosorwa ntakindi gishushanyo mbonera cyo kurinda amafaranga arenzegukora, bateri itakaza uburinzi burenze kandi ikizamini ntigishoboka gutsinda.

Muri make, birasabwa ko abayikora bakoresha uburyo bubiri bwo kurinda mugihe bategura bateri kugirango bahangane nimpinduka zishoboka.
