Description
The HKS is a high density and highly efficient, isolated DC-DC converter that operates over an input voltage range
of 35 to 75 VDC. It provides a 12 VDC nominal, fully regulated output at up to 32 Amperes of direct current. The
converter is an ideal choice for building a complete power system utilizing the Intermediate Bus Architecture (IBA).
The thermally-optimized construction of the HKS allows the unit to provide high output current over a wide
operating temperature range while maintaining a safe guardband for electrical and thermal component ratings.
The HKS employs 100% surface-mount components for consistency and reliability in the production process.
