NOTE: *1:
This is the experimental average value of sample n=3; This value is
not
the representative value nor guaranteed value.
*2:
This value does not include current in the capacitor of the EMI filter
circuit.
o
Output
NOTE: *1:
Output 1 does not include ripple and spike. Output 2 does not include
spike.
*2:
Output 1 indicates the value at
25°C, output 2 is not loaded when rated
input
voltage upper limit.
*3:
Ripple and Spike voltage value is for reference (at rated resistance load: at
25°C).
