Derating
Observe the derating when using the SIG350. The ambient temperature and the current
have an influence on the heating of the module.
The product provides temperature and current readings that you can display via the
web interface or read out via Dual Talk interfaces.
The following figure shows the maximum permissible current (I) that may be drawn by
the device, depending on the ambient temperature (T):
