10.2 Common Mode Surge Test Results
The results for common mode surge immunity testing are shown below (IEC 1000-4-5,
1.2/50 µs - 8/20 µs, L/N-G). For common mode tests, a three-wire AC cord was utilized.
AC Ground (PE) was tied from AC outlet to power supply output RTN through a copper
strap. There was a 2 Ω generator source impedance.
Compliance beyond Class 3 (2 kV), with no degradation, was confirmed.

10.3 Differential Mode 100 kHz Ring Wave Test Results
The results for differential mode 100 kHz Ring Wave immunity testing are shown below
(IEEE C62.41, L-N). For differential mode tests, a two-wire AC cord was utilized. AC
Ground (PE) was disconnected. There was a 12 Ω generator source impedance.
Compliance to 3 kV, with no degradation, was confirmed.
