5 Energy Transmission
The maximum transmittable power with the BIC system depends on the distance as well as
the axial and angular offset.
At a distance of 5 mm, a lateral offset of 5 mm and no angular offset, the output current
indicated in the electrical data of 1A is assured.
5.1 Derating
Explanations for increasing the maximum transmittable power as well as increasing the
maximum transmission distance.
Reducing the ambient temperature as well as the distance, lateral axis offset and angular
offset the maximum transmittable power can be increased. Similarly, if the power
requirements are low, the transmission distance of the BIC system, for example, can be
increased.
If the system is operated continually in a range over the maximum power at ambient
temperature, but not so severely loaded that it collapses, the status of the resulting over-
temperature is reported.
Note
If the BIC system is operated with a correspondingly severe load, the output
voltage of the Remote collapses with no message.
Remote Current
as a Function of
Ambient
Temperature
The following illustration shows the course of a typical derating curve for the BIC system at
3 mm distance.
The average of the output current is calculated as follows:
where I
Remote
is the average, T the reference time, and i
Remote
(t) the current draw over time.
Whereby time T
≈
should be considered to be 30..60min.
The max. available peak current is 5A.
Note
If a larger average output current is required at a resulting ambient temperature,
active cooling can be used to reduce the temperature surrounding the BIC so that
more current is available.
