AA-250-24-44-LK-XX

AA-250-24-44-00-XX Outdoor Thermoelectric Cooler Assemblies Thermoelectric Cooling Units for outdoor enclosures and kiosks The Outdoor Cooler Series is an Air-to-Air thermoelectric assembly (TEA) that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via convection. The AA-250 has 26% higher cooling capacity and a 21% boost in efficiency over standard models with same geometric configurations. Heat is absorbed and dissipated thru custom designed heat exchangers with high aspect ratio, air ducted shrouds and high performance fans. The heat pumping action occurs from custom designed thermoelectric modules that achieve a high coefficient of performance (COP) to minimize power consumption. * Patent Pending 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 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. FEATURES AND BENEFITS • 244W capacity rated at ΔT = 0ºC, Tambient = 35°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 • UL60950 and UL50 approval obtained by customers when integrated in telecom outdoor enclosures • Environmentally friendly solid state operation – no compressor or CFC refrigerants • Cooling and heating in the same unit; optional temperature controller reverses the polarity of current to generate heating Applications • • • • Americas: +1.919.597.7300 Europe: +46.31.420530 Asia: +86.755.2714.1166 ets.sales@lairdtech.com www.lairdtech.com/thermal Outdoor telecom enclosures Outdoor kiosks and displays Harsh condition electronic cabinets Battery cabinets AA-250-24-44-00-XX Outdoor Thermoelectric Cooler Assemblies PERFORMANCE Qc vs ΔT 250 Qc (W) 200 150 100 50 0 0 5 10 15 20 25 30 35 40 45 ΔT (°C) Specifications AA-250-24-44-00-XX Technical Technology Thermoelectric (TE) modules, forced air, closed loop (non-mixing), filter-less, non-refrigerant Cooling at dT = 0°C, and nominal / float voltage.1 Heating 2 Voltage (nominal / maximum) 244/262 W (832/894 BTU/hr) 250W (853 BTU/hr) 24/28 VDC 6 COP (Coefficient of Performance) 85% Grounding (all voltages) Positive or negative Current draw, ±10% (nominal / startup) Weight 12.1/15.1 A 6.3 kg (16.9 lbs) Panel mounting Through (from external side) ≥70,000 hours Fan life (L10 at +40°C) Connector type (on unit / mating side) Terminal block with cage clamps (AWG 28-12) Hi-pot testing 707 VDC Environmental Temperature range 3 (external ambient) -40°C to +55°C (-40°F to +131°F) Temperature range (internal enclosure) -20°C to +55°C (-4°F to +131°F) Degree of protection, enclosure 4 Degree of protection, unit internal side NEMA 4 (IP55) 5 Degree of protection, unit external side 5 Sound level (1m distance) Over-Temp Thermostat (internal and external side heat sink) IP54 IP54 63 dB(A) 75°C ± 6°C (accessory) Cooling capacities at nominal / float voltage are rated at external temperatures of +35°C and +50°C respectively.
