The DIO 120 series of dc/dc converters power electronic circuits floating on several kilovolts of operating voltage. They are typically used for high-power gate drivers and similar applications in oil and gas, mining, railway, and industrial environments.
The 120-W converters accept a single-input 24- or 48-Vdc and deliver 12-, 15 or 24-Vdc (5-A current limit) output. They are tested for corona (partial-discharge) extinction at a minimum of 10 kVrms and hi-pot tested for 20 kVrms. The feedback system on the primary side employs a sensing circuit instead of optical components, for improved reliability. Typical operating voltage potential between primary and secondary is 2 to 5 kVrms. These convection-cooled units are rated for operation from –20° to 50°C. They are filtered to meet EN55022 Class A conducted and radiated requirements and comply with UL 508 and equivalent industrial safety standards.
