10 W, Multiple Output, Isolated Power Supply
14 Surge Voltage
Ω
14.1 Differential = Line-to-Line (L-N), 2
Source Impedance.
The unit exceeded the 1 kV IEC/UL 1000-4-5 Class 3 requirement (meets Class 4, 2 kV).
Ω
14.2 Common Mode = Line-to-Ground (L-GND, N-GND), 12
Source Impedance
The unit exceeded the IEC/UL 1000-4-5 Class 3, 2 kV, meeting Class 4, 4 kV
requirements.
All three outputs had monitor LEDs that showed no output disruption during the 90 high
voltage surge pulses of Class 3 (FAST).
During Class 4 testing, the outputs were disrupted for one second (LEDs blinked) when

applying the 2 kV, 2
differential pulse and the 4 kV, 12
differential pulses (L1/GND,
L2/GND), indicating the overvoltage shutdown protection was triggered.
The outputs were unaffected during the 4 kV, 12 Ω common mode pulses (L1, L2/GND).
The unit was centered on the insulation side of a 6 in x 4 in single sided copper clad
board (1.4 mm insulation), to avoid surface or insulation breakdown during the voltage
surges.
The voltage was applied between the input terminals of the unit (L or N) and the copper
clad ground plane (GND), in the following sequence:
L (+4 kV) to GND, 5 times
L (-4 kV) to GND, 5 times
N (+4 kV) to GND, 5 times
N (-4 kV) to GND, 5 times
L, N (+4 kV) to GND, 5 times
L, N (-4 kV) to GND, 5 times
