Outdoor Thermoelectric Cooler Assemblies
Innovative Technology
With Bi-Polar Thermostatic Control
for a Connected World
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 25C, and heat when the internal temperature drops below 10C.
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 T = 0C, ambient = 32C
Wide operating temperature range of -40C to +55C
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 > 25C / heating mode < 10C)
APPLICATIONS
Outdoor telecom enclosures
Outdoor kiosks and displays

1)
Cooling capacities at nominal / float voltage are rated at external temperatures of 32C and 46C respectively. Float voltage is defined at 54 VDC.
2)
Heating capacity is rated at external temperature of -40C, nominal voltage, and dT = -45C.
3)
Controller function shall not operate the external fan during heating mode.
4)
The highest environmental protection level requires an external shroud and is defined as the protection level for the enclosure.
5)
Rating for unit without protective shroud.
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.
