Cov ntawv thov

Cov HWM021 series yog DIN rail peb theem active electronic energyntsuass. Lawv siv ntau yam thev naus laus zis siab heev ntawm kev tshawb fawb thiab kev txhim kho, xws li microelectronic-techniques, tshwj xeeb loj-scale IC (integrated circuit), digital sampling thiab processing technology, SMT technique, thiab lwm yam. Lawv cov kev ua tau zoo ua raws li International Standards IEC 62053-21 rau Class 1 peb theem zog nquag.ntsuasLawv tuaj yeem ntsuas qhov kev siv zog ntawm lub zog hauv peb theem AC network ntawm 50Hz lossis 60Hz ncaj qha thiab raug. Cov HWM021 series muaj ntau hom rau kev xaiv, kom haum rau ntau yam kev xav tau ntawm kev ua lag luam. Lawv muaj cov yam ntxwv nrog kev ntseeg siab zoo heev rau lub sijhawm ntev, me me, lub teeb yuag, zoo nkauj, yooj yim rau kev teeb tsa, thiab lwm yam.

Cov Haujlwm thiab Cov Nta

◆ 3 Muaj nyob rau hauv 35 hli DIN txheem rail mounted, ua raws li Cov Qauv DIN EN 50022, nrog rau pem hauv ntej PANEL mounted (qhov nruab nrab ntawm ob lub qhov mounting yog 63 hli).

◆ Ob txoj kev teeb tsa saum toj no yog xaiv tau rau tus neeg siv.

◆ Qhov dav ntawm 10 tus ncej (modulus 12.5mm). ua raws li Cov Qauv JB/T7121-1993.

◆ Xaiv tau lub step motor impulse register ntawm 6 tus lej (99999kWh) lossis 6 + 1 tus lej (999999. 1kWh) LCD zaub.

◆ Xaiv tau qhov chaw sib txuas lus infrared sab hauv thiab qhov chaw sib txuas lus RS485. Cov txheej txheem sib txuas lus ua raws li Cov Qauv DL/T645-1997. Lwm cov txheej txheem sib txuas lus kuj tseem xaiv tau.

◆ Xaiv tau lub roj teeb lithium uas tsis tas yuav kho kom zoo hauv LCD kom nyeem tau lub 'meter' thaum lub hwj chim raug txiav.

◆ S-kev sib txuas (hlau nkag los ntawm hauv qab thiab hlau tawm rau sab saum toj) muaj ob hom kev sib txuas: kev sib txuas ncaj qha thiab kev sib txuas CT rau kev xaiv. Rau kev sib txuas CT, muaj 27 hom CT nqi teeb tsa, tom qab teeb tsa CT, peb tuaj yeem nyeem lub 'meter' ncaj qha, tsis tas yuav nce tus nqi CT.

◆ Lub ntsuas kev sib txuas CT yog 7 tus lej LCD zaub: 5 + 2 tus lej (tsuas yog ntawm CT tus nqi yog 5: 5A) lossis 7

cov lej suav, uas yog nyob ntawm qhov teeb tsa CT tus nqi.

◆ Nruab nrog lub qhov hluav taws xob passive impulse output terminal, ua raws li Cov Qauv IEC 62053-31 thiab DIN 43864.

◆ Cov LEDs qhia txog lub xeev fais fab ntawm txhua theem, lub teeb liab zog thiab lub xeev sib txuas lus ntawm cov ntaub ntawv.

Kev tshawb nrhiav tsis siv neeg rau qhov kev taw qhia ntawm cov khoom thauj tam sim no thiab yuav raug qhia los ntawm LED.

◆ Ntsuas qhov kev siv zog nquag hauv ib qho kev taw qhia ntawm peb theem, uas tsis muaj feem cuam tshuam nrog qhov kev taw qhia tam sim no ntawm cov khoom thauj kiag li, ua raws li Cov Qauv IEC 62053-21.

◆ Lub hau luv luv ntawm lub davhlau ya nyob twg yog ua los ntawm lub PC pob tshab, kom txo qhov chaw teeb tsa thiab yooj yim rau kev teeb tsa hauv nruab nrab.
