Further Details Extreme PoE PSE Switches from Black Box power remote PoE devices such as security cameras and traffic signals in extreme environments with uncontrolled temperatures. The switches can even be used outdoors with protection from rainfall and standing water. Rugged metal cases serve as a heat sink to dissipate heat, giving these switches a wide temperature range of -40 to +167° F (-40 to +75° C). Plus, the cases are sealed to resist contaminants such as dust, dirt, moisture, smoke, and insects.
