WIDE-RANGE INPUT VOLTAGES Ib qho kev ua haujlwm siab ntawm cov khoom siv hluav taws xob tau txais ac lossis dc input voltages. Lub 120/240 V ac los yog 125 V dc input circuit (P0922YU) muab ntau yam ntawm 85 mus rau 265 V ac ntawm 47 mus rau 63 Hz ua haujlwm (los yog 108 txog 145 V dc) kom tau raws li qhov xav tau ntawm lub zog thoob ntiaj teb. Lub 24 V dc fais fab mov input circuit (P0922YC) lees txais ntau yam ntawm 18 V dc txog 35 V dc. HIGH EFFICIENCY Lub kaw lus kaw lub zog muaj qhov ua tau zoo tshwj xeeb (txog 95% rau P0922YU thiab mus txog 81% rau P0922YC) uas ua rau muaj kev ntseeg siab thiab qis qis. Lawv muaj qhov rov qab los ntawm kev nqis peev (ROI) tsawg dua ob xyoos raws li qhov nruab nrab ntawm cov hluav taws xob thiab kev thauj khoom. POWER FACTOR CORRECTION CIRCUITRY Cov qauv tsim siab tshaj plaws rau ac inputs (P0922YU) muab cov kev ua haujlwm sinusoidal tam sim no rau qhov ze ntawm kev tswj fais fab. TAM SIM NO Lub hwj huam mov ua haujlwm raws li qhov muaj qhov hluav taws xob tas mus li nrog qhov ntsuas siab tshaj plaws raws li teev nyob rau hauv cov lus qhia tshwj xeeb. Yog tias cov khoom thauj tam sim no sim siab tshaj 110% ntawm qhov siab tshaj plaws tam sim no ntawm qhov ntsuas 25 ° C, cov zis hluav taws xob pib txo qis mus rau xoom, yog li txwv qhov tam sim no xa mus rau lub load. Thaum tshem tawm ntawm overload, ib txwm ua haujlwm rov pib dua. OVERVOLTAGE SHUTDOWN Tsis siv neeg kaw tshwm sim yog tias kev ua haujlwm ua rau muaj qhov tso zis ntau dhau. Tom qab qhov tshwm sim ntawm qhov overvoltage kaw, lub hwj chim input yuav tsum tau cuam tshuam los tsim kom muaj qhov tso zis. Tom qab qhov ua rau raug tshem tawm, lub kaw lus kaw rov pib dua hauv tsawg dua 30 vib nas this tom qab tshem tawm lub zog tawm tswv yim. DIVISION 2, ZONE 2 APPLICATION Cov khoom siv hluav taws xob yog UL thiab UL-C teev (rau UL 1950) raws li muaj Kev Nyab Xeeb Ntxiv Tsawg Voltage (SELV) thiab tuaj yeem siv rau hauv Division 2 thiab Zone 2 daim ntawv thov. POWER FOR EXTERNAL FIELD DEVICES Qhov tseeb ntawm lub zog yuav tsum muaj nyob rau hauv tus qauv 200 Series subsystem nyob ntawm tus naj npawb ntawm Fieldbus Modules (FBMs) / Fieldbus Communication Modules (FCMs) / Field Control Processors (FCPs) raug siv, hom kev txiav tawm siv, thiab txawm tias siv hluav taws xob sab hauv lossis sab nraud yog siv rau lub teb.
