Protect Critical Power Electronics with High-Speed Fuses
POWR-SPEED® fuses specifically designed for protection of power semiconductor devices such as diodes, triacs, IGBTs, SCRs, MOSFETs and other solid state devices that are typically designed into power conversion and power conditioning equipment. 变频传动装置、逆变器、UPS、整流器和软启动器是配备灵敏功率半导体器件的典型设备实例，这类灵敏的功率半导体器件无法耐受任何线路浪涌或过流，并且需要高速保护。
Littelfuse POWR-SPEED® PSR Series products offer optimized circuit protection at the extremely fast speed required to protect modern day power conversion devices. 此类产品常见于纸浆和造纸行业、吊机和起重设备、加工行业、废水处理厂和各种大型工厂以及MRO设施等众多应用。
Our new high-speed QS Series fuses have reduced the energy let-through by up to 70% over previous generation high-speed semiconductor fuses. Our experts have designed high-performance silver fuse elements that combine with a hardened silica filler to provide enhanced system protection.
