• Up to 500W at 96.5% efficiency
• 1500V isolation
• Safety Agency Approvals
Description
The 07CN-70S “Cimarron” Series are isolated DC/DC converters that operate from a nominal 48V source.
These converters are intended to provide isolation and step down to generate an intermediate bus for the
purpose of powering non-isolated Point-of-Load (POL) converters. These units will provide up to 500W of
output power from a 48V input. These units are designed to be highly efficient and very low cost and are thus
unregulated. The downstream POL converters will provide the precise regulation required by the load.
Features include remote on/off, over current protection and undervoltage lockout. These converters are
provided in an industry standard half-brick package.
