Description

The RYK DC/DC converters are typically used in cost sensitive general purpose power isolation and

voltage matching applications. Despite their low cost, they are fully specified converters with a built-in

linear regulator to give a regulated, load-independent output. The converters are equipped with 4kVdc

isolation, industrial operating temperature range of -40°C to +105°C without derating, and UL/EN

certifications.
