High input voltage DC-DC converters offer a wide input voltage range and high output power – 5kW, 10kW, 15kW and higher
5kW, 600Vdc high input voltage industrial DC-DC converters (click on image for data sheet)
ABSOPULSE′s HVI 5K-3U7 series high input voltage industrial quality DC-DC converters use field proven FID2000 and KHI1200 design topology to generate 5kW output power. A built-in redundancy diode allows for parallel connection of a number of 5kW converter units to create a 10kW, 15kW, or higher DC-power solution, or N+1 redundancy. The output separation diode also makes the units suitable for battery charging applications.
The DC-DC converter accepts 600Vdc input, with a wide input range of 400V to 800Vdc. Output options include 24V, 48V, 110Vdc, 125Vdc or custom. Output regulation is ±1% combined across all input line and load conditions, including output separation diode. Efficiency is a minimum of 85% at full load depending on input/output configuration required.
The converters are equipped with heavy filtering on the input and output for low noise. The input meets EN55032 Class A with wide margins (Class B as an option). This ensures that the units can be used in EMI sensitive environments without additional filtering.
To ensure high reliability and long operating life, all critical components on the primary side are designed and tested for corona inception levels that are significantly higher than the operating voltages. The design is verified for 5600Vdc input to output isolation and production level testing is 4300Vdc input to output.
The units are equipped with reverse polarity protection, inrush current limiting, output current limiting, short-circuit protection and self-resetting thermal shut-down in the case of insufficient airflow.
High quality built-in fans provide sufficient airflow for operation within a 0°C to 50°C temperature range without de-rating. The fans draw air into the unit, and exhaust at the terminal side of the unit. All heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. This also ensures exceptional mechanical ruggedness. Conformal coating provides protection against humidity and airborne contaminants.
The HVI 5K-3U7 unit is enclosed in a 3U7 132 x 432 x 382 mm chassis-mount package. A 19” rack-mounted version also available
