QKS48T21120-PCA0 - 

The QKS is a high density and highly efficient, isolated DC-DC converter that operates over an input voltage range of 36 VDC to 75 VDC. It provides a 12 VDC nominal, loosely regulated output voltage at up to 21 A _DC of 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 QKS allows the unit to provide high output current over a wide operating temperature range while maintaining a safe guardband for component electrical and thermal ratings. The QKS employs 100% surface-mount components for consistency and reliability in the production process.
