Littelfuse，，，，Inc. has announced a new line of high-speed fuses for protection of power semiconductor devices used in industrial equipment. The POWR-SPEED line of fuses uses a special bridge design, quenching material and element designs to provide fast, extreme current limitation.
当今的制造系统使用电源半导体设备来控制驱动器并优化功率利用率。这些半导体组件对过电流的损坏很敏感，因此需要使用非常快速的高速保险丝进行保护。如果没有过电流保护，重要的电力系统（例如VFD控件，软启动器，交流驱动器，直流驱动器和电源转换器）将面临故障和停机的风险。
Littelfuse产品经理Craig Greeson表示：“ OEM设计工程师和分销商一直在要求Littelfuse提供高速半导体保险丝，因为他们想从信任的名称中购买。Littelfuse已有40年的能力保护专家。”
POWR速度融合设计大大降低了峰值亮起电流和触发能量（I2T），以最大程度地保护半导体设备的保护。它通过许多设计功能来完成此操作，包括“弧栏”技术，这是一种专门设计的聚合物材料，用于限制和淬火弧。它还具有低瓦损耗值，可节省在标称操作期间以热的形式浪费的能量。
POWR-SPEED保险丝是comp替代etitor’s fuses. Optimized for both performance and energy efficiency, they are easy for OEM engineers to specify. Technical data and application support are also readily available from Littelfuse, while design engineers looking for a customized fuse design are encouraged to contact the Littelfuse Application Support Team.
The initial launch includes a 700VAC/DC series and 500VAC/DC series in the traditional North American bolted style. Current ratings range from 35 to 800A for both series. Interrupting ratings are 200kA AC and50kA DC (time constant: 10ms).
