Tair is defined as ambient air temperature surrounding the LC1200R.
Note 1: | Tair < | 32°C | : 95% RH maximum. |
| Tair > | 32°C | : Absolute humidity content not to exceed 100% at 32oC. |
Note 2: | Tair @ | < 48 hours | |
| Tair @ | 60°C | < 168 hours |
Note 3: Slight background color changes are allowed depending on ambient temperature. This phenomenon is reversible.
Note 4: High temperature operation assumes the use of an enclosure that properly directs the fan airflow
Note 5: Upper operating temperature limit of 60°C is without solar loading.
Reference to "room ambient" is interpreted as 20°C - 25°C
For product reliability predictions, the assumed temperature profile is:
