THERMOELECTRIC COOLING UNITS FOR OUTDOOR ENCLOSURES AND KIOSKS
The AA Outdoor Cooler Series is an Air-Air Thermoelectric Assembly (TEA) that uses
impingement flow to transfer heat. It offers dependable, compact performance by cooling or
heating enclosures via convection. A bi-polar thermostatic controller with predetermined set
points is integrated into the TEA. The unit is programmed to cool when the temperature inside
the enclosure exceeds 25°C, and heat when the internal temperature drops below 10°C.
This product series has been designed to pass rigorous Telcordia test requirements conducted
by our customers, such as earthquake resistance, salt fog, wind-driven rain, high temperature
exposure and dust contaminants. This is due to the selection of world-class components
such as brand name fans with the highest degree of environmental protection and lifetime
guaranteed waterproof connectors, heavy duty anodization on the high-density heat sinks,
overheat protection, and double environmental seals for the thermoelectric modules (TEMs).
FEATURES AND BENEFITS
• 150W capacity rated at ΔT = 0ºC, ambient = 32°C
• Wide operating temperature range of -40°C to +55°C
• Telcordia GR-487-CORE tested and verified by customers when integrated
in telecom outdoor enclosures
• Gaskets, connectors, and fans provide a NEMA 4 seal for the enclosure
• UL 60950 and UL 50 approval obtained by customers when integrated in
telecom outdoor enclosures
• Environmentally friendly solid-state operation – no compressor or CFC refrigerants
• Bi-polar thermostatic control (cooling mode > 25°C / heating mode < 10°C)
APPLICATIONS
• Outdoor telecom enclosures
• Outdoor kiosks and displays
• Harsh condition electronic cabinets
• Battery cabinets

Note:The specified performance of any Laird Technologies cooling unit is dependent on how it is handled and incorporated into the final product. This includes elements such
as the system design, insulation design, and assembly method. While Laird Technologies is able to provide general guidelines based upon our experience, it is ultimately
the responsibility of the device manufacturer to validate each product and its performance for its intended use.
