ABSOPULSE’s Liquid-Cooled DC-DC Converter Delivers up to 2000W

August 30, 2019 Alix Paultre

ABSOPULSE Electronics’ LQC 2K-3U2LC liquid cooled, industrial DC-DC converter can deliver up to 2000W from an input of 600Vdc (400Vdc to 800Vdc range) with a 24Vdc/80A output. A built-in output separation diode allows parallel connection of several units for higher system output, andustom input/output voltages are also available. The converter is designed for dense enclosed spaces where heatsinks, fans, or pure convection cooling are not feasible.

The cold plate has an embedded tube running a loop of coolant liquid, to ensure a -25ºC to +50ºC coolant temperature range. The unit is connected to an external cooling system, which provides the liquid coolant. Optional internal temperature sensors can be installed to monitor the liquid coolant temperature.

The LQC 2K-3U2LC is equipped with heavy filtering on the input and output, which contributes to low noise. This ensures that the converters can be used in EMI sensitive environments without additional filtering. The input meets EN55032 Class A with wide margins; Class B is available as an option.
