Single Phase DC Multifunction Meter

 

Say single phase DC multifunction meter et indesinyo na kompanya mi parad saray aplikasyon a singa say balon energy vehicle charging stations, solar power supply, telecommunications base stations, tan building automation. Sayan single phase DC multifunction meter et balon henerasyon na melag ya intelihente ya DC electric energy meter, ya manguusar na estandarten DIN35mm rail mounted installation, walaan na modular ya istruktura tan bentaha na modular ya desinyo circuit ya mankakasakey ya sukat, melag so sukat, mainomay ya i-install, tan mainomay ya i-network.

Gawaen na panagsukat

Walay forward tan reverse DC energy metering functions to tan sarag ton isimpen so data to; Walay time-sharing metering function to, say enerhiya na kuryente et natipon, natipon, tan nakarga ed loob na 1-4 ya panaon unong ed mipetekan iran panaon; Nayarin isimpen so dagup ya enerhiya na kuryente ed loob na anggad 12 bulan; Say oras na pangisimpen na data et 24:00 ed sampot na bulan, odino say oras ed baetan na koma-1 tan koma-28 na kada bulan.

Pansukat tan Panbantay

Sarag ton sukaten, irekord, tan ipanengneng so kaplesan ya boltahe, kaplesan, pakayari, tan karakel na metro na enerhiya na kuryente, ya walay lingo ed panagsukat (reference error) ya ag onlampas ed ± 1%.

Gawaen na Komunikasyon

Walay saksakey ya RS485 interface, ya sarag toy mankolekta na dual loop data. Say communication protocol DL/T 645-2007 et adesinyo pian mipara ed Modbus RTU, tan sarag na saray manguusar ya usaren dan mismo. Say kapeles na komunikasyon et 1200bps~9600b, tan say default et 204bps.

I-reset so metro

Say electric energy meter et nayarin manggawa na reset operation ed lebel na baterya no walay autorisasyon tan security verification, tan say reset operation et permanentin nirekord bilang sakey ya ebento.

Ipanengneng so Gawaen

Walay button ya pangipanengneng;

Say display content et naapag ed taloran klase: numerical values, codes, tan symbols;

Saray nipanengneng ya numerical units et mangaagamil ed saray national legal measurement units;

Susuportaan toy pangipanengneng na lebel na baterya ed 0-4 ya decimal places.

Panagyelo na gagala

Daily freeze: mangisimpen na dagup na positibo tan negatibon aktibon pakayari tan nanduruman rate na enerhiya na kuryente tan nanduruman data ed pegley-labi kada agew, tan nayarin mangisimpen na data ed loob na duaran bulan;

Timed freezing: Sarag ton isimpen so dagup na positibo tan negatibon aktibon pakayari, ontan met ed enerhiya tan variable data na kada rate, tan i-freeze to so data na 60 beses ed loob na sakey a panaon.

Say DC electronic multi rate energy meter et walaan na micro-controller module, voltage sampling module, current sampling module, 485 communication unit, LCD display module, tan working power module. Say voltage sampling module et mankokolekta na voltage signals panamegley na atagey-precision, abeban- temperature drift voltage divider resistors;Say current sampling module et mankokolekta na current signals panamegley na manganese copper shunt;Kayari na nantutumbokan ya digital processing ed loob na microprocessor, saray nakolekta ya signals et nauman ed pulse signals ya proporsyonal ed power parad time-sharing accumulation, ya manresulta ed kabuoan ya konsumo na kuryente tan nanduruman taripa. sarag ton gawaen so remote data exchange tan upload parameters a singa saray electrical parameters, ebento, freezeing, oras, tan arum niran parameters ed energy meter. Sayan energy meter et mangiiter na dakel a functions, kaiba lay energy metering, panag-iponpon tan panagproseso na impormasyon, panag-monitor ed tuan panaon, automatic control, tan panag-upload na impormasyon.
