Low cost Features 1:1 Input voltage range DC/DC Converter Efficiency up to 81% Unregulated 4kVDC/1 second isolation Converters IEC/EN/UL certified RKE/H Description 1 Watt The RKE/H DC/DC converters are typically used in cost sensitive general purpose power isolation and SIP7 voltage matching applications. Despite their low cost, they are fully specified converters with 4kVdc isolation, industrial operating temperature range of -40C to +85C without derating and UL/EN Single Output certifications.
