6.2 Temperature range
It is recommended that you use SLM750 at -30
℃
~+75
℃
and take temperature control
measures when applications are in the harsh environment conditions. At the same time, a limited
operating temperature range of the module should be provided. Under this temperature conditions,
some of the indicators may exceed. It is suggested that you store the applications under certain
temperature conditions. Modules beyond this range may not work or are damaged.
