_________________________________________ 在上述的所有情况下，直流源都能够提供大电流。一旦发生故障，必须安全切断短路电流或过载电流。而在交流电情况下能够完全适用的由石英砂构成的熔断保险丝，换在直流电压环境下，可能遇到重大的挑战。 问题在哪里？
重申：“通常情况”不是问题。但是仔细规划不放过任一可能性的技术人员眼中总能发现例外情况。这不代表对“通常情况”的保险，而是“意外险”。一台设定为交流电输入的电源，在通常情况下也能接直流电输入工作。但问题是，能保证不发生意外吗？大多数开关电源生产商都无法对此做出承诺。 在变频器中间直流总线下工作：
变频器的中间直流总线是由边缘陡峭的相对于保护地的高交流电压（共模电压）叠加而成的。接此类输入直流电的电源必须能够处理这种干扰，通常需要内置一个特殊滤波器。
熔断保险丝：
作为在发生故障时的最后的安全保障，电源中需要内置熔断保险丝。那么问题来了：电源所使用的这种类型的熔断保险丝是否能够在高直流电压下切断短路电流或者过载电流？首先，似乎短路情况下就存在问题，虽然不是必然的。例如，通过熔丝上的电流达额定电流的3倍。在这种类型的故障下，不适用于直流电的熔丝不能被可靠熔断，而由此产生的热量很可能引起火灾 RELIANCE ELECTRIC 1AC4103G USPP 1AC4103GRELIANCE ELECTRIC 14C-104 USPP 14C104 RELIANCE ELECTRIC 04900113 RELIANCE ELECTRIC 052003 RELIANCE ELECTRIC 3V4150 USPP 3V4150 RELIANCE ELECTRIC 61C365 4 OUTPUT ANALOG RELIANCE ELECTRIC 0-57404-1E USPP 0574041E RELIANCE ELECTRIC 57C-404C USPP 57C404C RELIANCE ELECTRIC 0-57404 USPP 057404 RELIANCE ELECTRIC 0-57404-1 USPP 0574041 RELIANCE ELECTRIC 0-57404-1F USPP 0574041F RELIANCE ELECTRIC 0-57404-1H USPP 0574041H RELIANCE ELECTRIC 0-57404-3A USPP 0574043A RELIANCE ELECTRIC 57C-404-2A USPP 57C4042A RELIANCE ELECTRIC 57C-404A USPP 57C404A RELIANCE ELECTRIC 57C-404B USPP 57C404B RELIANCE ELECTRIC 57C-404 USPP 57C404 RELIANCE ELECTRIC 0-51864 USPP 051864 RELIANCE ELECTRIC 0-49007-4 NSFP 0490074 RELIANCE ELECTRIC 1DB2005 NSFP 1DB2005 RELIANCE ELECTRIC 0-51381-16 USPP 05138116 RELIANCE ELECTRIC 0-51381-1 USPP 0513811 RELIANCE ELECTRIC 0-51381-14 USPP 05138114 RELIANCE ELECTRIC 2GU41001 NSPP 2GU41001 RELIANCE ELECTRIC 1V4440 NSFP 1V4440 Reliance Electric Thyristor Assembly 86474-7S Reliance Electric 0-56313-1 controller inverter 0563131 Reliance Electric Processor Module 0-57407-4J 0574074J RELIANCE ELECTRIC 2CB4020 NSFP 2CB4020 RELIANCE ELECTRIC 14C30 USPP 14C30 RELIANCE ELECTRIC 811627 USPP 811627 RELIANCE ELECTRIC 1AC2003U USPP 1AC2003U RELIANCE ELECTRIC 0-49067 USPP 049067 RELIANCE ELECTRIC 0-51829 USPP 051829 RELIANCE ELECTRIC 0-49026-9 USPP 0490269 RELIANCE ELECTRIC 0-51878 USPP 051878 RELIANCE ELECTRIC 6SP401-3P4CTNN NSFP 6SP4013P4CTNN RELIANCE ELECTRIC 831677 USPP 831677 RELIANCE ELECTRIC 45C35 INTERFACE MODULE AUTOMATE 35 RELIANCE ELECTRIC 0-52712-10 NSPP 05271210 RELIANCE ELECTRIC 0-57170 DRIVER BOARD 057170 NEW FS RELIANCE ELECTRIC 30 HP DC MOTOR 1750/2300 RPM RELIANCE ELECTRIC 0-49005-5 LINEAR VOLTAGE TIME UNIT RELIANCE ELECTRIC 0-52823 NSPP 052823 RELIANCE ELECTRIC 11C-57S USPP 11C57S Reliance Electric 0-52808 OLVA Control Board New RELIANCE ELECTRIC 402422-3F RESISTOR 4024223F NIB RELIANCE ELECTRIC 0-52851 NSPP 052851 RELIANCE ELECTRIC 86466-059S USPP 86466059S RELIANCE ELECTRIC 0-57416-P NSFP 057416P RELIANCE ELECTRIC 0-51881-1 NSFP 0518811 RELIANCE ELECTRIC 14C-68 USPP 14C68 RELIANCE ELECTRIC 802285-79 NSPP 80228579 Reliance Electric 0-54381 Sequence Detector Card NEW RELIANCE ELECTRIC 0-51849-1 USPP 0518491 RELIANCE ELECTRIC 2GU21005 USPP 2GU21005 RELIANCE ELECTRIC 831679 USPP 831679 RELIANCE ELECTRIC B79B4237M-TZ NSFP B79B4237MTZ RELIANCE ELECTRIC 0-54349-2 NSPP 0543492 RELIANCE ELECTRIC ULDE CARD 0-51847-4 NEW RELIANCE ELECTRIC 1AC2002 NSFP 1AC2002 RELIANCE ELECTRIC 0-54400-3 USPP 0544003 RELIANCE ELECTRIC 0-54400-7 USPP 0544007 Reliance Electric 0-57413-E Communications RELIANCE ELECTRIC 0-57402-D NSFP 057402D RELIANCE ELECTRIC 0-56963-A NSFP 056963A RELIANCE ELECTRIC 0-52808 USPP 052808 RELIANCE ELECTRIC 0-52711-4 NSFP 0527114 RELIANCE ELECTRIC 86006-A NSFP 86006A RELIANCE ELECTRIC 86007-A NSFP 86007A RELIANCE ELECTRIC 0-51903 USPP 051903 RELIANCE ELECTRIC 0-51831-5 USPP 0518315 RELIANCE ELECTRIC 0-49061 USPP 049061 RELIANCE ELECTRIC 0-57409 NSFP 057409 RELIANCE ELECTRIC 0-51377-2 USPP 0513772 RELIANCE ELECTRIC GP200 AC Reliance Electric Analog Output 57C410 New Open Box RELIANCE ELECTRIC 6033-03-812 USPP 603303812 RELIANCE ELECTRIC CARDPAK D-49011-6A DRIVER Reliance Electric 846664-R UCC1 Card 846664R New RELIANCE ELECTRIC 803456-8R USPP 8034568R RELIANCE ELECTRIC 803456-8RA USPP 8034568RA RELIANCE ELECTRIC 8960611 USPP 8960611 RELIANCE ELECTRIC 59025-1SU USPP 590251SU RELIANCE ELECTRIC 330-128 USPP 330128 RELIANCE ELECTRIC 3RA29020 USPP 3RA29020 RELIANCE ELECTRIC 801429-5SB USPP 8014295SB 25 hp , 1765 rpm Reliance Electric Motor Reliance Electric 57407-4F 68000 CPU Module 574074F New Reliance Electric MinPak Plus 14C23 230VAC 35A 1PH Reliance Electric Brushless AC Servo Controller HR2000 Reliance Electric 10 HP E-Master Motor 3495 RPM MK-1207 RELIANCE ELECTRIC MAXPAK 3 VS DRIVE NEW RELIANCE ELECTRIC 57401-2 574012 DRIVE DIGITAL I/O Reliance Electric Sabre motor 20HP RELIANCE ELECTRIC 57C331A BRAND Reliance Electric 2V4451 GV3000 2HP AC Inverter Reliance 50 HP Electric Motor.
