西門子電源板的工作原理： 1、通電后副電源先啟動(dòng)工作，為主電路板微處理器控制系統(tǒng)提供正5伏的工作電壓。 2、開(kāi)機(jī)后，副電源為PFC功率因數(shù)校正電路驅(qū)動(dòng)控制電路UCC28051、主開(kāi)關(guān)電源驅(qū)動(dòng)巨制電路DLA001的提供 VCC—ON供電，主開(kāi)關(guān)電源啟動(dòng)工作，向主電路板負(fù)載電路提供正24伏和正12伏兩種電壓。 3、經(jīng)過(guò)抗干擾電路濾除市電中的雜波干擾，整流、PFC電感、濾波輸出300V直流電壓到副電源電路，副電源開(kāi)始工作輸出+5v電壓。 4、經(jīng)西門子電源板輸出排插端口1腳到數(shù)字板CPU電路，CPU電路經(jīng)過(guò)讀取數(shù)據(jù)開(kāi)機(jī)輸出高電平開(kāi)機(jī)電壓。 5、經(jīng)西門子電源板排插端口2腳到電源板穩(wěn)壓開(kāi)關(guān)機(jī)控制電路，開(kāi)關(guān)機(jī)控制電路工作，輸出電壓到PFC振蕩電路，輸出高頻方渡脈沖推動(dòng)PFC開(kāi)關(guān)管工作，利用PFC電感產(chǎn)生的逆程脈沖。 6、經(jīng)過(guò)整流、濾波生成400V的PFC電壓。PFC電壓送到主電源電路和PFC電壓檢測(cè)電路，PFC檢測(cè)電路檢測(cè)到PFC電壓達(dá)到400V，PFC檢測(cè)開(kāi)關(guān)電路輸出電壓到主電源震蕩電路，振蕩電路輸出高頻方波脈沖到主電源功率開(kāi)關(guān)管電路。 7、開(kāi)關(guān)管工作推動(dòng)開(kāi)關(guān)變壓器工作，從次級(jí)感應(yīng)輸出2組電壓，經(jīng)過(guò)整流、濾波輸出+12V、+24V電壓。到此，整個(gè)西門子電源板啟動(dòng)過(guò)程完成。 8、電視待機(jī)時(shí)，采用切斷PFC功率因數(shù)校正電路驅(qū)動(dòng)控制電路UCC28051、主開(kāi)關(guān)電源驅(qū)動(dòng)控制電路DLA00l的VCC—ON供電，主電源停止工作。 Opto 22 SNAP-AIV-I 2 Channel Isolated NEW NEW OPTO 22 SNAP ANALOG VOLTAGE INPUT MODULE ±10,±5 VDC SNAP-AIV-I NEW OPTO 22 SNAP-AIV-8 ANALOG INPUT MODULE 8 CHANNEL FOR SNAP PAC SYSTEM SNAP-AIV OPTO 22 -10VDC TO +10VDC ANALOG INPUT MODULE OPTO 22 SNAP ANALOG Part No. SNAP AIV 2 Channel Voltage Input Opto 22 SNAP-AIV 2 Channel Analog Module OPTO 22 SNAP-AIV NSFP SNAPAIV OPTO 22 SNAP-AIV-8 NSFP SNAPAIV8 OPTO 22 SNAP-AIV-8 USPP SNAPAIV8 OPTO 22 RACK I/O MODULES SNAP ANALOG AITM AIV IDC5 FAST SNAPB3000 SNAPB12MC OPTO 22 RACK I/O MODULES SNAP AIVRMS AIV AOV ODC5R ODC5SRC SNAPB3000 SNAPB12MC OPTO 22 SNAP-AIV-72 USPP SNAPAIV72 ALFA-LAVAL LKB53A-6700-4A-E-S NEW ALFA LAVAL LKB53 VALVE REPAIR KIT Alfa Laval LKB53A-6000T BUTTERFLY VALVE 2-1/2" ALFA LAVAL LKB53A-6000-1 1/2-E-316L *USED* ALFA LAVAL LKB51A-2-1/2-E-S-G NSFP LKB51A212ESG ALPHA LAVAL / TRI CLOVER LKB53A-6100TKT-3E-316L-R170236 3" S/S SANITARY VALVE Mitsubishi Drive MDS-C1-V1-3535 From Canada MITSUBISHI ELECTRIC MDS-B-V2-3535 SERVO DRIVE UNIT Mitsubishi MDS-DH-V2-8040 Servo Drive Mazak Mitsubishi Servo Drive MDS-B-V2-2020 MDSBV22020 Tested!
