Epson FX-2190 Service Manual

EPSON FX-890/2190 Revision B
Operating Principles Overview 51
Note “*1”: Each value indicated here is only the average of measured values of samples
(sample size n = 3), that is, it is not a typical value or guaranteed value.
“*2” : Each value does not include the current flowing in the capacitor of the EMI filter
circuit.
OUTPUT SPECIFICATIONS
Note “*1”: Neither Output 1 nor Output 2 includes the spike voltage component.
“*2” : The output current during power supply startup must be not greater than the value
specified above.
“*3” : The values for ripple and spike voltage indicated above, which are the values with a
rated resistance load, are only for reference. (Ambient temperature: 25
°C)
For measurement, connect a KMF50V470µF electrolytic capacitor and 0.1 µF film
capacitor to the output 1 terminal, and a KME16V47
µF electrolytic capacitor and
0.1
µF film capacitor to the output 2 terminal.
