HVI 500P-D3G
600 Vdc High Input Voltage DC/DC Converter
This series of rugged, industrial quality, high input voltage DC/DC converters utilize KHR 301 topology to generate the required output power. This technology enables a significantly more compact construction than previous high input voltage designs at this output power level. The converters accept a nominal input voltage of 600Vdc, with a 400V to 800V input range. To ensure high reliability and long operating life, all critical components on the primary side are designed and tested for corona inception levels, which are significantly higher than the operating voltages. The units are packaged in waterproof, rugged, die cast aluminium IP66 enclosures. The input and output are via sealed cable glands, circular connectors or custom connections. The internal converter unit is entirely potied with a thermally conductive MIL-grade silicon rubber compound for immunity to high levels of shock and vibration. Cooling is by conduction and convection via the walls of the IP66 enclosure. If installed on a heat-sinking surface, cooling is further enhanced and the converters achieve higher output power. An optional built-in redundancy diode allows for a number of units to be connected in parallel to achieve higher output power or N+1 redundancy. The output separation diode also makes the unit suitable for batiery charging applications. Full electronic protection, low component count, large design headroom, and the use of components with established reliability result in a high MTBF. The series is manufactured at our plant under strict quality control.
