AA-230-48-44-00-XX Dual Cold Side Outdoor Thermoelectric Cooler 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-230 has 230 Watts of cooling capacity and can be mounted in a horizontal direction to save space. 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. 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 Patent No.: US 9,360,240 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 Americas: +1.919.597.7300 connectors, heavy duty anodization on the high-density heat sinks, Europe: +46.31.420530 overheat protection, and double environmental seals for the Asia: +86.755.2714.1166 thermoelectric modules. ets.sales@lairdtech.com www.lairdtech.com FEATURES APPLICATIONS • Horizontal mount • Outdoor telecom enclosures configuration • Outdoor kiosks and displays • 230W capacity rated at ΔT = • Harsh condition electronic 0°C, Tambient = 35°C cabinets • Wide operating temperature • Battery cabinets range of -40°C to +55°C • Gaskets, connectors, and fans provide a NEMA 4 seal for the enclosure • 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 Page 1 of 3 AA-230-48-44-00-XX PERFORMANCE Qc vs ΔT SPECIFICATIONS TECHNICAL Technology Thermoelectric modules, forced air, closed loop (non-mixing), filterless, non-refrigerant 1 Cooling at ΔT = 0°C, and nominal / float voltage 230/246W (785/840 Btu/h) 2 Heating (calculated) 250W (853 Btu/h) 6 Voltage (nominal / maximum) 48/56 VDC COP (Coefficient of Performance) 80% Grounding (all voltages) Positive or negative Current draw, ±10% (nominal / startup) 6.1/7.8 A Weight 6.5 kg (14.3 lbs) Panel mounting Through (from external side) Fan life (L at +40°C) ≥70,000 hours 10 Connector type (on unit / mating side) Terminal block with cage clamps (AWG 28-12) Hi-pot testing 707 VDC ENVIRONMENTAL 3 Temperature range (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) 4 Degree of protection, enclosure NEMA 4 (IP55) Degree of protection, unit int. side IP54 5 Degree of protection, unit ext. side IP54 Sound level (1m distance) 65 dB(A) Over temp Thermostat (optional) 1) Cooling capacities at nominal / float voltage are rated at external temperatures of +35°C and +50°C respectively.
