5-10. Allowable power supply range

The figure below shows the ranges in which operation at the rated load is possible for given

gap and displacement, when transmitting and receiving transformers are facing each other. X

axis shows the direction along short size of transmitting and receiving transformers, and Y axis

shows the direction along long side of the transformers.

※The actual allowable power supply range is influenced by environment surrounding the

mounting position, and can be bigger or smaller.

The allowable range below is given for room temperature and under the condition that no

metal objects are placed around the transformer.

6． Insulation resistance and withstand voltage

6

–1. Insulation resistance:

・PFC module

Between all inputs and outputs and FG (housing)

50MΩ or higher using DC500V megger

・Power transmitting module

Between all inputs and outputs and aluminum case of transmitting transformer

50MΩ or higher

using DC500V megger

・Power receiving module

Between all inputs and outputs and rear aluminum plate

50MΩ or higher using DC500V megger

6-2. Withstand voltage:

・PFC module

Between all inputs and outputs and FG (housing)

AC1500V during 1 minute, no

failures

・Power transmitting module

Between all inputs and outputs and aluminum case of transmitting transformer AC1500V during 1

minute, no failures

・Power receiving module

Between all inputs and outputs and rear aluminum plate AC500V during 1 minute, no failures

※ To obtain this value for the PFC module, six spacers of 7 mm or more length were mounted on

the housing.
