ABSOPULSE Electronics’ LQC 2K-3U2LC is a liquid cooled, industrial quality DC-DC converter that uses field-proven technology to deliver up to 2000W output power. The unit accepts 600Vdc input, 400Vdc to 800Vdc operating input range and provides 24Vdc/80A output. A built-in output separation diode allows parallel connection of several units for higher system output. Custom input/output voltages are also available. The unit is equipped with an output-fail alarm and Form C contacts are available on request. Optional remote shutdown or enable are available.

The LQC 2K-3U2LC liquid cooled converter is designed for dense enclosed spaces where heatsinks, fan or pure convection cooling are not feasible. The unit is typically used in vehicles, industrial automation and similar heavy-duty applications.

The LQC 2K-3U2LC is cooled entirely by liquid coolant. The cold plate has an embedded tube running a loop of coolant liquid which ensures a -25ºC to +50ºC coolant temperature range for full specification. The unit is connected to the external customer 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.

The design is verified for 5600Vdc input to output isolation and production level testing is 4300Vdc input to output. Other protection features include inrush current limiting, reverse polarity protection, and overload and overvoltage protection. The unit meets the requirements of EN60950-1, IEC61010 and corresponding industrial standards.
