描述
這種變頻器輸入側(cè)變壓器采用多相移位技術(shù),輸出側(cè)采用多電平正弦PWM技術(shù),諧波較低,在無輸出濾波器的情況下,就可使THD<1%,其單元串聯(lián)的數(shù)量決定輸出電壓的等級,所以它可適用于任何普通的高壓電動(dòng)機(jī)。雖然采用這種結(jié)構(gòu)會使器件的數(shù)量增加,但由于驅(qū)動(dòng)功率下降,開關(guān)頻率較低且不必采用均壓電路,系統(tǒng)的效率仍可達(dá)97%,功率因數(shù)可達(dá)0.95以上。另外,在某個(gè)功率單元出現(xiàn)故障時(shí),可自動(dòng)退出系統(tǒng),而其余的功率單元可繼續(xù)保持電機(jī)的運(yùn)行,減少停機(jī)時(shí)造成的損失,便于冗余設(shè)計(jì),技術(shù)上較成熟。主營:本特利,英維思,伍德沃德,福克斯波羅、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。Force Computers SYS68K CPU-40B/4-01 VME MVMEForce SYS68K/CPU-6 880-12537-101.A?2 LAM 810-17034-300-1FORCE COMPUTERS SYS68K/CPU-6AForce SYS68K CPU-30LiteFORCE COMPUTER VME SYS68K CPU-30ZBE PROCESSOR BOARDFORCE SYS68K DRAM VME BOARD MVME MAINFRAME MOTOROLAForce SYS68K CPU-33B/4 VME BoardForce SYS68K ISIO-1 Serial I/O BoardFORCE SYS68K SRAM-4A VME BOARD MVME MAINFRAME MOTOROLAFORCE PROCESSOR BOARD Model SYS68K ASCU-2FORCE SYS68K ISCSI-1 VME BOARD MVME MAINFRAME MOTOROLAFORCE COMPUTERS SYS68K CPU-6AFORCE CONTROL BOARD SYS68K ISI0-2/C2(P/N 220062)FORCE SYS68K CPU-2VF VME SINGLE BOARD COMPUTER MOTOROLAForce SYS68K/CPU-6A A7307 Rev D VME MVME BoardForce SYS68K/SASI-1 Lam research 810-017035-001 Rev.BForce SYS68K/Eagle-01?C User’s ManualForce SYS68K/SASI-1FORCE SYS68K ISIO-2 MODULE ASSYForce SYS68K CPU-40 B/16 VME BoardBUS TRONIC FORCE SYS68K MAINFRAME BOARDS NICE LOTForce SYS68K/CPU-6A/C?3 810-017034-300 rev.AForce SYS68K/CPU-30BE SYS68K/CPU-30BE?/16/C2 VME ModuleForce SYS68K/CPU-33B/?4 VME Board CAT#:510098 PN:600-1FORCE SYS68K/WFC-1 Floppy Controller VME Board 300001Force SYS68K/ISIO-1FP I/O Controller Dual Board w CableForce SYS68K/CPU-33B/?4 VME Board CAT#:510098FORCE SYS68K CPU BOARD 310004 WORKINGForce SYS68K/ISIO-1FP I/O Controller Dual Board 310034Force SYS68K/ISIO-2 I/O Controller Board PN:310031FORCE COMPUTER CPU BOARD SYS68K CPU-1B NEW-NO BOXFORCE COMPUTER VME BOARD MODEL SYS68K REV CFORCE COMPUTERS SYS68K/CPU-6A USPP SYS68KCPU6AFORCE COMPUTER MODEL SYS68K SASI-1441 LAM REV AForce SYS68K CPU30ZBE CPU-30ZBE CPU Module VMEbus VMEFORCE COMPUTERS SYS68K/CPU-6VA USPP SYS68KCPU6VAForce SYS68K/ISIO-2 I/O Controller Board PN:310031Force SYS68K/ISIO-1FP I/O Controller Dual Board 310034FORCE COMPUTERS SYS68K/PWR-09A USPP SYS68KPWR09AForce SYS68K/CPU-33B/?4 VME Board CAT#:510098特價(jià)現(xiàn)貨處理:6GK1161-3AA006GK1161-3AA016ES7972-0AA01-0AA06ES7307-1EA00-0AA06ES7341-1AH01-0AE06ES7332-5HD01-0AB06ES7443-1EX11-0XE06ES7331-7PF10-0AB06ES7318-2AJ10-0AB06ES7321-1BL00-0AA06ES7322-1HH01-0AA06ES7972-0BA52-0XA06AV6545-0BA15-2AX06AV6545-0BC15-2AX06AV6545-0CC10-0AX0SAFTRONICS EZ6-125Starter EZ6-40Saftronics AA1049
