(4) To obtain the sum of the input voltage and positive output voltage
- The output current must be lower than the rated current.
- Total Output voltage regulation is sum of input voltage regulation and output voltage regulation.
- If the output voltage is shorted, a large current may flow depending on the input voltage source.
3. Using Dual Output Type
(1) Using dual output type
(2) Using ±12V as 24V output
(3) Using ±12 V as multiple outputs: +12 V and +24 V
(4) Using as 48V output
