Because the current output from the OUT-terminal is the sum of
the +24V and the +12V outputs, this value must not exceed the
rated output current. In the HDF-0512D, this value is 125 mA.

The output current capacity is the same as the output current
capacity of the converter. (For example, an HDF-0505 connected
as shown above has an output rating of 10 VDC at 600 mA.
