High-Quality Power Modules at Low Cost

DC/DC

Whether regulated or unregulated, isolated to 10kVDC, or carefully designed for extremely high ambient temperatures of +100°C - RECOM offers a suitable DC/DC converter for every application. Unregulated DC/DC converters are typically used in general purpose power isolation and voltage matching applications and feature a full industrial operating temperature range of -40°C up to +85°C without derating. Regulated DC/DC converters are designed for industrial applications, can drive high capacitive loads and operate over a broad temperature range without derating. Furthermore they provide stable output voltages when the input voltage suddenly changes.
