Lub tsheb ciav hlau watthour meter integrates high-precision metrology unit module thiab ib 8052 MCU thiab nws cov peripheral modules. Lub metrological module muaj siab metering raug thiab tuaj yeem ntsuas qhov tam sim no thiab voltage RMS ntawm txhua theem, cov theem thiab tag nrho cov active, reactive thiab kab sib chaws, thiab lwm yam. Kev khiav hauj lwm tsis, overload ntau. On-chip MCU 8052 nrog 16K FLASH thiab 512BRAM thiab ntau yam peripheral modules, tsis tshua muaj hluav taws xob kub them rau-chip RTC module, LCD tsav module, fais fab tswj module, SPI / I2C interface module thiab UART kev sib txuas lus module.
Rail meter tsim tag nrho suav nrog cov qauv ntawm miniaturization, tus nqi-zoo, kev txawj ntse thiab kev ntseeg siab, muaj cov yam ntxwv hauv qab no:
1, ntsuas tag nrho lub zog ua haujlwm, rov qab tag nrho lub zog.
2, xaiv lub sijhawm sib koom ntau lub zog ntsuas kev ua haujlwm.
3, txhawb RS485 kev sib txuas lus interface, kev sib txuas lus raws tu qauv xaiv tau (MODBUS-RTU lossis DL / T645 raws tu qauv), nrog rau hluav taws xob hluav taws xob mem tes tso zis.
4, kev nkag mus tam sim no, kev nkag mus tau thib ob tuaj yeem ua tau, lub teeb liab hluav taws xob hluav taws xob, tsis tas yuav muaj lub zog txhawb nqa.
5, me me, qhov dav ntawm qhov sib npaug ntawm 18mm, nrog kev sib xyaw ua ke zoo tshaj plaws ntawm cov khoom siv hluav taws xob me me, nrog cov hlau lead tiv thaiv.
6, DIN35mm txheem rail installation, yooj yim rau muab txhua yam teeb pom kev zoo lub thawv thiab teeb pom kev zoo txee.
7,7 dav kub LCD zaub, log zaub.
