很过变频器维修公司为了节省维修成本,或者很多老款的变频器的模块在市场上很难找到新模块,一般使用旧模块来代替,但在购买模块的时候,也就对模块的真假识别也有一定的技术含量。判定模块的质量也是维修工程师维修变频器关键！首先你要看模块是否被拆开过（看外观痕迹EFB0924HHF），现在有很多模块是维修过的，参数正常但质量很差！耐压值是***重要的参数，可用耐压表测量，输入380V的变频器的输出模块耐压值要大于1000V，220V则要600V！电流则可用电容表来比较判定大小,目前很多不诚信的供应商把小模块的标签磨掉,然后印上大模块的标签,所以用电容表来量容量也是关节,可以很快判断其真假。IGBT模块还可以用指针式万用表10K档检测其是否能动作，用指针（黑—红）去触发模块的G—E，可使模块C—E导通，当G—E短接时则C—E关闭！这方法是***简单***基本的测量方法，是维修新手可以做到的，***的可不是这样测量！台达风扇代理销售询购产品，欢迎咨询！常用稳压二极管的型号及稳压值如下表，型号1N47281N47291N47301N47321N47331N47341N47351N47441N47501N47511N4761，稳压值3.3V3.6V3.9V4.7V5.1V5.6V6.2V15V27V30V75V，电感在电路中常用“L”加数字表示，如：L6表示编号为6的电感。电感线圈是将绝缘的导线在绝缘的骨架上绕一定的圈数制成。直流可通过线圈，直流电阻就是导线本身的电阻，压降很小；当交流信号通过线圈时，线圈，两端将会产生自感电动势，自感电动势的方向与外加电压的方向相反，阻碍交流的通过，所以电感的特性是通直流阻交流，频率越高，线圈阻抗越大。电感在电路中可与电容组成振荡电路。EFB0924HHF电感一般有直标法和色标法，色标法与电阻类似。如：棕、黑、金、金表示1uH（误差5%）的电感。9EC2048H0019EC2048A001109P0512T7H11109E1348A102109P1348H102109E1348S102109P0512T7H112109P0612T6H122109P0812T6H112109P0612T6H12109P0612T6H122109R0612T4H12109E1348A101109P1348H101109E1348S101109P0612T7H12109P0612T6H112109R0812T4H12109P0612T6H11109P0612T6H112109R0612T4H11109E1348G102109P1348S102109R0612T4H122109P0612T7H11109R0612T4H12109R0812T4H11109R0812T4H12109R0812T4H1229WP0612H402109E1348G101109P1348S101109R0612T4H112109P0612T7H122109R0612T4H11109R0812T4H122109R0812T4H11109R0812T4H1129WP0612H401109R0812T4H112109L0612H402109L0612G402109L0612S402109L0612F402109L0612M4029WP0812H4029WP0824H4029WP0924F402109P0912T4H12109L0612H401109L0612G401109L0612S401109L0612F401109L0612M4019WP0812H4019WP0824H4019WP0924F401109P0912T4H11109L0624H402109L0848H402109L0624S402109L0624F402109L0624M4029WP1248H1029WG1212H102-E9WG1224H102-E109P0912T4H122109L0624H401109L0848H401109L0624S401109L0624F401109L0624M401西门子变频器风扇K2E250-AA01-09西门子变频器风扇K2E250-AA01-09电压:230风量:1450,m3/h离心风机K2E250-AA0西门子变频器风扇K2E220-AB06-09西门子变频器风扇K2E220-AB06-09离心风扇K2E220-AB06-09转速:2550min-1电压:230电流:0EBMK2E225-AA26-09西门子变频器专用风机EBMK2E225-AA26-09西门子变频器专用风机ECOFIT离心风机2RREu15，180X35RECOFIT离心风机2RREu15，180X35R离心风扇2RREu15转速:2RREu15电压:2RREu15电流:2RREu1ABB系列变频器风扇/风机，ABB系列变频器风扇/风机，ABB变频器风扇/风机ABBABB变频器风扇/风机电机功率:AABB变频器风机3BHE003088R0002ABB变频器风机3BHE003088R0002离心风扇ABB励磁风机3BHE003088R0002电机功率:ABB励磁风机HIE***9036P0004ABB励磁风机HIE***9036P0004离心风扇ABB励磁风机HIE***9036P0004电机功率:ABB变频器风机3BHE003088R0003ABB变频器风机3BHE003088R0003离心风扇ABB变频器风机3BHE003088R0003电机功率ABB励磁风机HIER465117P0001ABB励磁风机HIER465117P0001离心风扇瑞士风扇HIER465117P0001电机功率:HIE轴流风扇ABB励磁风机3BHE003088R0002电机功率:ABB变频器风机3HAC029105-001现ABB变频器风机3HAC029105-001现轴流风扇ABB3HAC029105-001电压:24围ABB冷却风机1238HH24B-WDB机器人专用ABB冷却风机1238HH24B-WDB机器人专用直流风扇ABB1238HH24B-WDB电压:24ABB变频器风机3HAC12924-2实惠ABB变频器风机3HAC12924-2实惠直流风扇ABB变频风机3HAC12924-2.电压:24适用西门子变频器风机GR45G-4DK.4I.2R西门子变频器风机GR45G-4DK.4I.2R离心风扇施乐百GR45G-4DK.4I.2R电机功率:ABB变频器风扇GR35C-2DK.6N.1R，ABB变频器风扇GR35C-2DK.6N.1R，离心风扇施乐百ZIEHL-ABEGGGR35C-2DK.6N.1ABB变频器风机G2E140-PI32-43ABB变频器风机G2E140-PI32-43离心风扇EBM-papstG2E140-PI32-43围EFB0924HHF瑞士风机GDRM42-133B-2瑞士风机GDRM42-133B-2电压:GDRM42-133B-2风量:GDRM42-133B-2离心风扇型ABB变频器ACS800-37-1160-7+C129风扇ABB变频器ACS800-37-1160-7+C129风扇离心风扇ABB变频器风扇ACS800-37-1160-7+C12ABB变频器风扇ACS800-U31-0060-5ABB变频器风扇ACS800-U31-0060-5离心风扇ABB变频器风扇ACS800-U31-0060-5适用ABB变频器风扇ACS800-37-0440-7+C129ABB变频器风扇ACS800-37-0440-7+C129)
