6.2 Test Set-Up
The basic test set-up to measure parameters such as efficiency and
load regulation is shown in Figure 1. When testing the Intronics AC60
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

6.3 Output Ripple and Noise Measurement
The test set-up for noise and ripple measurements is shown in Figure 2.
Measured method :
Add a 0.1 uF ceramic capacitor and a 10 uF electrolytic capacitor to
output at 20 MHz Band Width.
Terminal wire 800mmMin

6.4 Installation Instruction
Please use the mounting hold as:
AC60 series :
4 holds of
ψ3.17
And insert the spacer (Maxψ6) of height over 8mm to lift the unit .The
vibration spec. is the value take when the unit is raised by 8mm spacers.
Where V
FL
is the output voltage at full load
V
NL
is the output voltage at 10% load
The value of line regulation is defined as:
Where V
