• UL/ULC Listed for dual monitor addressable modules using a standard outdoor listed station down to -70°F (-57°C).
• Enclosure rated to NEMA 3R Standards.
• UL/ULC Listing does not require standby or secondary power for 110 VAC 60 Hz heaters.

• The thick, clear polycarbonate cover is UV-stabilized.
• Fan runs continuously to maintain a uniform temperature inside the enclosure.
• Heater unit cycles as required to maintain the correct range of operating temperature.
• Polycarbonate backed by a three year guarantee against breakage in normal use (one year on electro mechanical and electronic components).
