The DY120-DD400-72 is a DC/DC converter that converts a DC voltage from 72V to 400V DC voltage and can provide a DC current of 300mA.

Converter from 72V to 400V

The 120W converter has an input range of 61.2V to 82.8V DC. The output voltage is equipped with a fine adjustment that allows the output voltage to be adjusted with a range of 392V – 408V DC.

The converter is protected against overloading, overvoltage and undervoltage. The converter has a large over-capacity, which enables it to deliver 150W (370mA) for brief moments.

This 400V converter also provides galvanic separation between the input and output.

Custom models

These converters are available with a wide range of input and output voltages. In the datasheet you will find an overview of the standard versions. In addition to the standard versions, we also supply converters that are fully tailored to your requirements. Any DC voltage from 12V up to 700V DC for input or output is possible (100W up to 1000W). Use our contact form to ask about the possibilities.


These converters are suitable for situations where a DC voltage of a certain value must be brought to 400V.

Some application examples:

  • Power supply for PLCs, control systems or other peripherals
  • Raising or lowering boat or vehicle voltage
  • Stabilising voltage in sustainable energy generation
