An Digital Multi-function Power Meter ni wasan gajarta mai zurfi na iya haɗa wanda ya harkar da cin bayanai masu zama, harkokin daidaito, da kuma harkokin tushen lura. Tana yi amfani da interfaas na ƙirƙira na lambar a cikin kayan aikin da ke sakamako bayanan daidai game da wasan karami kunne. Yana da muhimmanci wajen haɗa ci gaban yadda ake amfani da energy, taimaka wa tattalin arziki, da kuma tara zimma a kan gaban automatizaciya na gwamnati, tattalin gwamnati, data centers, da kuma wasu sauran wasan karami.
Funktsiyoyin Dukkan, A Cikin Muhimmiyar:
Cin Bayanai Masu Zama: Tana bincike parametoci masu mahimmanci a cikin wasan karami kamar voltage (na fadin), current (na ruwa), active/reactive/apparent power, power factor, frequency, etc., a cikin zamantakewa, ta hanyar zama (na masu zama).
Metering Energy: Tana cin bayanai active energy da reactive energy (import/export) da zama, tana ba shi zaman lafiya don binciken yadda ake amfani da energy da kula.
Insa na Power Quality: Tana ba shi zama don in ba da harmonic content, voltage/current unbalance, etc., tana taimaka wajen zama da quality of power supply.
Ƙirƙira Na Lambar: Tana amfani da high-brightness LED or LCD display (yana da kyau biyu ko duk), tana ƙirƙira bayanai daidai da kuma da zaman lafiya da bayanai da suka fi, tana taimaka ƙirƙira a matsayin.
Harkokin Lura Da Zama: Tana harkar da RS485, tana taimaka Modbus-RTU, Profibus, CANopen (kafin ya faru a model), tana ba shi yawan harkoki a cikin SCADA, EMS, BMS da wasu sauran wasu don remote monitoring and data acquisition (SCADA).
Alarming Na Zama: Tana ba shi out-of-limit alarm functionality, tana samar da voltage anomalies ko current overload.
Data Logging: Wasu models suna da historical data logging capability, tana taimaka history tracing and analysis.
Abubuwan Da Su Duka, Suna Da Zama:
Zama Da Zaman Lafiya: Tana ba shi stable measurements da accurate, trustworthy data, tana ba shi high-standard application requirements.
Integrating Da Funktsiyoyin Dukkan: Tana ba shi multiple monitoring needs da meter dukkan, reducing installation complexity and cost.
Sabon Install: Tana ba shi multiple form factors (square or DIN-rail mounted), tana taimaka easy adaptation a cikin distribution panels/cabinets (switchboard/cabinet).
Compatibility Da Zama: Tana amfani da standard communication protocols, tana ba shi easy integration a cikin wasu sauran wasu.
