TE Connectivity HC-STAK 25 HV Interconnection Systems
TE Connectivity's HC-STAK 25 HV Interconnection Systems offer a safer, more reliable connection suitable for connector voltages up to 1000VDC. These systems are specifically designed to meet the increased connectivity requirements of high-voltage interconnection systems for hybrid and all-electric vehicles. The HC-STAK 25 High-Voltage (HV) interconnection systems provide scalable, reliable high-power distribution to each aggregate throughout the lifetime of the vehicle. These systems offer a double-ended fork terminal that provides a low contact resistance arrangement while meeting sealing, shielding, and touch-safe requirements in a very compact package.
The HC-STAK 25 HV interconnection systems provide the flexibility to interconnect with a wide range of conductor cross-sections, geometries, and materials. Typical applications include hybrid and electric vehicle powertrains, HV battery and inverter systems, E-motors, and power distribution.
