Bourns has expanded its POWrFuse high power fuse product family with the PF-F and PF-M series high power rating industrial fuse links specially designed to meet the UL248-13 semiconductor (aR) standard. These fuses help protect sensitive power semiconductor devices against overcurrent events in power inverters, converters, rectifiers, AC/DC drives, UPS systems and reduced voltage motor starters.
The PF-F series features 800VAC/VDC voltage, power ratings from 50 to 400A and up to a 100kA@800 VAC and 50kA@800VDC interrupting rating. The PF-M series provides 240VAC/150VDC voltage, power ratings from 50 to 180A and up to a 160kA@240VAC and 50kA@150VDC interrupting rating.
Both series are bolt mounted, offer fast-acting protection under fault current, low resistance and power loss and have an operating temperature range of -55 to 125°C. They are UL recognized to help OEMs save qualification time, while enhancing quality and reliability.
The series is available now and RoHS compliant and halogen free.
