Daim ntawv thov

HWM021 series yog DIN rail peb theem nquag hluav taws xob hluav taws xobmeters. Lawv tau txais ntau cov thev naus laus zis ntawm kev tshawb fawb thiab kev tsim kho, xws li microelectronic-techniques, tshwj xeeb loj-scale IC (integrated circuit), digital sampling thiab processing technology, SMT cov txheej txheem, thiab lwm yam. Lawv cov kev ua tau zoo ua tiav raws li International Standards IEC 62053-21 rau Chav Kawm 1 peb theem zogmeter. Lawv tuaj yeem ntsuas ncaj qha thiab raug ntsuas cov khoom siv hluav taws xob siv hluav taws xob hauv peb theem AC tes hauj lwm ntawm qhov ntsuas zaus 50Hz lossis 60Hz. HWM021 series muaj ntau hom kev xaiv, kom haum nrog ntau yam kev lag luam xav tau. Lawv muaj cov yam ntxwv nrog kev ntseeg tau ntev ntev, ntim me me, lub teeb yuag, zoo nkauj zoo nkauj, yooj yim installation, thiab lwm yam.

Muaj nuj nqi thiab nta

◆ 3 Muaj raws li 35 hli DIN tus qauv rail mounted, ua raws li cov qauv DIN EN 50022, nrog rau pem hauv ntej vaj huam sib luag mounted (qhov nruab nrab ntawm ob qhov mounting yog 63 hli).

◆ Ob txoj kev mounted saum toj no yog xaiv tau rau cov neeg siv.

◆ 10 ncej dav (modulus 12.5mm). Ua raws li Cov Qauv JB/T7121-1993.

◆ Xaiv tau cov kauj ruam lub cev muaj zog impulse register ntawm 6 tus lej (99999kWh) lossis 6 + 1 tus lej (999999. 1kWh) LCD zaub.

◆ Muaj peev xwm xaiv qhov chaw nyob deb infrared cov ntaub ntawv sib txuas lus thiab RS485 cov ntaub ntawv sib txuas lus chaw nres nkoj. Kev sib txuas lus raws tu qauv ua raws li Cov Qauv DL/T645-1997. Lwm qhov kev sib txuas lus raws tu qauv kuj tuaj yeem xaiv.

◆ tuaj yeem xaiv cov roj teeb lithium tsis pub dawb rau hauv LCD kom nyeem cov ntsuas ntsuas thaum lub zog raug txiav.

◆ S-kev sib txuas (inlet hlau los ntawm hauv qab thiab qhov hluav taws xob xaim nyob rau sab saum toj) muaj ob hom kev sib txuas: kev sib txuas ncaj qha thiab CT kev sib txuas rau kev xaiv, Rau CT kev sib txuas, muaj 27 hom CT tus nqi los teeb tsa, tom qab teeb tsa CT, peb tuaj yeem nyeem cov ntsuas ncaj qha, tsis tas yuav muab cov nqi CT sib npaug.

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

integers, uas yog nyob ntawm qhov teeb tsa CT tus nqi.

◆ Nruab nrog lub polarity passive zog impulse output davhlau ya nyob twg, ua raws li cov qauv IEC 62053-31 thiab DIN 43864.

◆ LEDs qhia nyias lub zog lub xeev ntawm txhua theem, lub zog impulse teeb liab thiab cov ntaub ntawv kev sib txuas lus xeev.

Tsis siv neeg tshawb nrhiav rau lub load tam sim no ntws kev taw qhia thiab yuav qhia los ntawm LED.

◆ Ntsuas lub zog siv hluav taws xob nyob rau hauv ib qho kev taw qhia ntawm peb theem, uas tsis cuam tshuam nrog lub load tam sim no ntws kev taw qhia txhua, ua raws li Cov Qauv IEC 62053-21.

◆ Lub hau npog luv luv yog tsim nrog lub PC pob tshab, kom txo tau qhov chaw nruab thiab yooj yim rau nruab hauv nruab nrab.
