AA-150-24-44-LK-XX 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 Harsh condition electronic cabinets Battery cabinets global solutions: local support TM Americas: +1.888.246.9050 Europe: +46.31.704.67.57 Asia: +86.755.2714.1166 CLV-customerservice lairdtech.com www.lairdtech.com/thermalAA-150-24-44-LK-XX Outdoor Thermoelectric Cooler Assemblies Innovative Technology With Bi-Polar Thermostatic Control for a Connected World PERFORMANCE Qc VS T 160 140 120 100 80 60 40 20 0 0 5 10 15 20 25 30 35 40 dT (C) SPECIFICATIONS AA-150-24-44-LK-XX Technical Technology Thermoelectric modules, forced air, closed loop (non-mixing), filterless, non-refrigerant 1 Cooling at dT = 0C, and nominal / float voltage. 143/159W (488/543 Btu/h) 2 Heating 150W (512 Btu/h) Voltage (nominal / maximum) 24/28 VDC Grounding (all voltages) Positive or negative Current draw, 10% (nominal / startup) 7.9/10.0 A (24V version) Weight 5.1 kg (11.2 lbs) Panel mounting Through Fan life (L at +40C) 70,000 hours 10 Number of connectors 1 Connector type On unit: AMP part number: 350777-1, 794269, 350547-6, 794270-1 (on unit / mating side) Mating side: AMP part number : 350778-1, 350550-6, 794270-1 Hi-pot testing 707 VDC Environmental 3 Temperature range (external ambient) -40C to +55C (-40F to +131F) Temperature range (internal enclosure) -20C to +55C (-4F to +131F) Overheating thermostat 80C 3C (Hot and cold side heat sink surfaces) 4 Degree of protection, enclosure NEMA 4 (IP55) 5 Degree of protection, unit IP54 Sound level (1m distance) 58 dB(A) Over-Temp Thermostat (hot and cold side heat sink) 80C 3C LK-81 Bi-Polar Controller Regulation On / Off Thermostatic control set point Cooling 25C +/- 2C, Heating 10C +/-2C Hysteresis 3C Low voltage disconnect/reconnect (LVD/LVD-R) 25.0/26.0V +/- 0.5V 1) Cooling capacities at nominal / float voltage are rated at external temperatures of 32C and 46C respectively. Float voltage is defined at 27 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.
