If a TSI must be setup in a very hot region, i.e., 45C, will it operate properly?
The TSI-440 is rated to 34 degrees C; for higher temperature locations the TSI-880 is rated to 44 degrees C. We have tested the TSI-880 up to 75 degrees C for short duration conditions. However, prolonged long term heat stress on the electronics may shorten life. The true environmental heat load on the system is quite complex as much depends on the duration of any high temperature conditions as well as solar loading and prevailing wind speed. Auxiliary cooling systems and heat shields are available – consult the factory for information about permanent operation at desert sites.
