5kW high input voltage dc-dc converters have built-in redundancy diode
ABSOPULSE ELECTRONICS HVI 5K-3U7 series of high input voltage industrial dc-dc converters deliver up to 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 and N+1 operation. The output separation diode also makes units suitable for battery charging applications. Products accept 600Vdc input (400V to 800Vdc range). 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 design is verified for 5600Vdc input to output isolation and production level testing is 4300Vdc input to output. Units comply with the requirements of EN/IEC 61010-1 and related standards. Units have reverse polarity protection, inrush and output current limiting, short-circuit protection and self-resetting thermal shut-down in the case of insufficient airflow.
