PSR032DS1000X電路保護的電氣專用保險絲規(guī)格書PDF中文資料

Description

Littelfuse PSR series high-speed square body fuses are

specially 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.

Variable frequency drives, inverters, UPS, rectifiers, and

soft-starters are examples of typical equipment designed

with sensitive power semiconductor devices that cannot

withstand any line surge or overcurrent conditions and

require high-speed protection.

Littelfuse POWR-SPEED? PSR series products offer

optimized circuit protection at the extremely fast speed

required to protect modern day power conversion devices.

Available in DIN43653 blade style termination with visual

blown fuse indication standard on all fuses and optional

micro-switch for external indication.
