DC-DC converters of the state-of-the-art technologies, and effective and
easy-to-use noise filters.

1. The case applying the reverse polarity output


2. The case applying input voltage on output voltage


    * Output current should be the same as rated current of the DC converter.
    * Please note that the excessive current flows from an input power supply
      to a load through a DC/DC converter when the output is short circuit.
    * The change in the output voltage is the sum of the change in the input
      voltage and the output of DC-DC converter.

3. The case using a multiple output unit as a single output unit


4. Other usage


    * Currents of 12V and 24V output flow to 0V line. Please make sure that
      the sum of these values doesn't exceed a rated current of a DC-DC converter.
