Transformer Operating Environment Designed for 40,000 hour operating life with repeated switching in 40° C ambient and 90% relative humidity environment.

For High Ambient Applications Designed to withstand the intense heat produced by incandescent trac lighting. Tolerates sustained case temperatures of 100° C. All components meet rigid heat tolerance standards and pass over temperature life tests. This rugged transformer is capable of operation during repeated on-off switching, as well as starting and continuous running in 40° C ambients and 90% relative humidity.
