ABSOPULSE Electronics released the HVI 5K-3U7 series of high-input-voltage industrial DC-DC converters, delivering up to 5kW of output power. A built-in redundancy diode allows for N+1 operation and parallel connection of a number of 5kW converter units to create a 10kW, 15kW, or higher DC-power solution.
Accepting 600Vdc input (400V to 800Vdc range), device 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 chassis-mount units measure 132 x 432 x 407 mm, have reverse polarity protection, inrush and output current limiting, short-circuit protection and self-resetting thermal shut-down in the case of insufficient airflow. The converters are equipped with heavy filtering on the input and output for low noise. The input meets EN 55032 Class A with wide margins, with Class B available as an option.
