Operating Principles
Operating Principles of Electric Circuitry
Output specifications
Note "*1": The values of Output 1 do not include any ripple or spike. The values of Output 2
and 3 do not include any spike.
"*2": The ripple and spike voltage are reference values with a rated resistance load
applied. (Ambient temperature: 25°C)
For the measurement of Output 1, connect a 47uF electrolytic capacitor and 0.1
µ
F
film capacitor to the output.
For the measurement of Output 2 or 3, connect a 0.1
µ
F film capacitor to the output.
"*3": A maximum of 2.1 A output current is permitted as long as it does not continue for
more than 10 ms.
"*4": 13 V or above when Output 2 is 150mA, Output 3 has no load, and Output 1 is 35mA
or more. 21 V or above when Output 2 has no load, Output 1 and 3 have the
maximum load.
Note "*1": Output 4, 5 and 6 do not include any spike.
"*2": The ripple and spike voltage are reference values with a rated resistance load
applied. (Ambient temperature:25°C)
Protective functions
Note "*1": Intermittent operation in which operation period is about 12%.
"*2": Outputs of the C583 MAIN Board
"*3": The overvoltage protection function is constituted outside the Power Supply Unit.
