Description
The SRCA-16S10L is an isolated dc/dc bus converter that operates from a nominal 48 Vdc source. This
converter is intended to provide isolation and step down to generate an intermediate bus for the purpose of
powering non-isolated Point-of-Load (POL) converters. This unit will provide up to 160 W of output power from a
nominal 48 Vdc input. This unit is designed to be highly efficient and cost effective. The downstream POL
converters will provide the precise regulation required by the load. Features include remote on/off, over current
protection and under-voltage lockout. This converter is provided in an industry standard sixteenth-brick package.
