POWR-SPEED® PSR series high-speed family now includes new bolted and DIN blade models
芝加哥，2019年10月24日 - Littelfuse公司 a global manufacturer of leading technologies in circuit protection, power control, and sensing, announced today the expansion of its award-winning line of POWR-SPEED® PSR series high-speed fuses by adding 275 new bolted and DIN mounting options in various sizes and amperages to meet global market needs.
These PSR series fuses are used in power conversion and power conditioning equipment to provide overcurrent protection for critical power semiconductor devices such as diodes, triacs, IGBTs (insulated-gate bipolar transistors), SCRs (silicon controlled rectifiers), and MOSFETs (metal-oxide semiconductor field-effect transistors). Plus, the square body design accommodates up to 2,000 amperage with up to 70 percent DC interrupting rating in a smaller footprint. This unique, compact design saves space providing more design flexibility in power systems.
“Modern day power semiconductor devices are especially vulnerable to thermal surges and overcurrent conditions,” said Sakthidharan Krishnamoorthy, product manager, Littelfuse Industrial Business Unit. “PSR series fuses are engineered to optimize protection and reduce the amount of short circuit current to extend the life of these power semiconductor devices.”
Other key benefits of the PSR series include:
- Different mounting terminations, including bladed and flush mount options, to meet a broader range of applications
- Unique silicon sealant prevents filler leakage to increase fuse reliability and keep equipment safe
- Up to 20 percent more DC voltage in standard package size than existing products
- Up to 70 percent more DC interrupting rating than existing products
- Third-party DC certification printed on product label, along with extensive published DC information with global certifications, helps streamlines UL inspections
These fuses are ideal for:
- Power conversion device protection (UPS, inverters, rectifiers, drives)
- Battery protection applications (energy storage systems)
- 电动汽车充电站
- High power DC systems (DC common bus, DC injection braking)
- Heaters and welding equipment
- 电源
