4.3.4 WPP & WSP Physical Positioning
faces as shown below.
At the charger system's nominal output voltage, the full 1,000 W can be delivered in all combinations of
gap and misalignment up to 20 mm. However, when the output voltage is above nominal value the gap
and misalignment does have an impact on the amount of power that can be delivered, with the worst
case being at the charger system's maximum working voltage, and is shown in the following table:
Air-gap
0 - 6 mm
8 mm
10 mm
12 mm
14 mm
16 mm
18 - 20 mm
For example
● If the gap is 10 mm, 1,000 W can be delivered if the misalignment is 17 mm or less
● If the misalignment is 5 mm, 1,000 W can be delivered if the gap is 20 mm or less

For example, the WPB runs more efficiently at higher input voltages and therefore its losses are lower. Input voltage does not have an impact on the losses of any other component.
