Lantern Thermal Management; Lantern Data - Iridium Sealite SL-510-SA Installation & Service Manual

The lantern incorporates a dynamic intensity module as part of the thermal management system that
ensures it operates within the thermal design window. In practice the thermal management system
limits the lanterns average power consumption by automatically adjusting the intensity to prevent
overheating.
The Thermal Management system does so by multiplying the flash character duty cycle with the
lantern intensity and compares this figure to the Thermal Limit. All the SL-510-SA models have the
same Thermal limits for all colours. If the figure (called the "multiplier") is greater than the Thermal
Limit the intensity is then adjusted to ensure the Thermal Limit is not exceeded.
This Thermal Limit will come into effect if you select a flash characteristic with a heavy-duty cycle and
set a very high intensity. Under these conditions the lantern will automatically reduce its intensity so
that it is operating within the thermal design window. Note, this intensity limit will not be reached for
the clear majority of applications.
The following tables detail the electrical power consumption of the SL-510-SA-5D and 10D lanterns:.
