HVI 300-F3

High Input Voltage – DC/DC Converter 300W

This rugged, industrial quality DC/DC converter series uses field-proven design topology to generate the specified output power. Higher output power is possible by using forced air-cooling. The unit accepts an input voltage of 600Vdc. An optional built-in redundancy diode would allow 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 battery charging applications. 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 unit is cooled by natural air convection and requires no fans. Full electronic protection, low component count, large design headroom, and the use of components with established reliability result in a high MTBF. The unit is manufactured at our plant under strict quality control.
