High-Power Fuse Series Optimized for High-Voltage EV/HEV Application Accessory Circuit Protection

­Bourns, Inc., announced a new POWrFuse High-Power Fuse model series. Bourns specifically designed the POWrFuse Model PF-K Series to meet ISO 8820-8 standards for the protection of high-voltage accessory circuits in electric vehicles (EVs) and hybrid electric vehicles (HEVs). These circuits are found in a variety of EV/HEV applications including electrical energy storage (ESS), battery disconnect units (BDUs) and battery management systems (BMS).

These new high-voltage EV fuses support operation up to 500 VDC and feature a 20 kA at 500 VDC interrupting rating and an extended temperature range of -55 to +125 °C. Individual models within the PF-K Series have current ratings from 15 to 50 A and are available in bolt and PCB mounting options. In addition, the latest POWrFuse™ EV fuses have been tested to Bourns’ internal automotive quality standards for environmental reliability, transient current cycling and device electrical and fusing characteristics.
