7.3 Test Set-Up
7.4 Output Ripple and Noise Measurement
The test set-up for noise and ripple measurements is shown in Figure
10. Measured method :
The basic test set-up to measure parameters such as efficiency and
load regulation is shown in Figure 8. When testing the Intronics power’s
AC100 series under any transient conditions please ensure that the
transient response of the source is sufficient to power the equipment
under test. We can calculate the
Add a terminal wire is 50mmMIN that the output end needs to connect
the sub length of line of one end .
1. Add a 0.1 uF ceramic capacitor and a 220 uF electrolytic capacitor
to output at 20 MHz Band Width for AC100S050 , AC100S090 and
AC100S120.

2. Add a 0.1 uF ceramic capacitor and a 10 uF electrolytic capacitor to
output at 20 MHz Band Width for AC100S150 , AC100S180 ,
AC100S240 and AC100S480.

7.5 Output Capacitance
Intronics power’ AC100 series converters provide unconditional stability
with or without external capacitors. Intronics power’ converters are
designed to work with load capacitance up-to 1000uF per amp.
