AA-480-48-44-00-XX Outdoor Thermoelectric Cooler THERMOELECTRIC COOLING UNITS FOR OUTDOOR ENCLOSURES AND KIOSKS The AA-480 Outdoor Thermoelectric Cooler 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-480 has 480 Watts of cooling capacity and a COP of 1 at ΔT = 0°C. 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 for outdoor environments. 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 exchangers, overheat protection, and double environmental seals for the thermoelectric modules. FEATURES AND BENEFITS • 480W capacity rated at ΔT = 0°C, Tambient = 35°C • Wide operating temperature range of -40°C to +55°C • Power cycle tested up to 100K cycles • 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 APPLICATIONS • Outdoor telecom enclosures • Outdoor kiosks and displays • Harsh condition electronic cabinets • Battery cabinets Americas: +1.919.597.7300 Europe: +46.31.420530 Asia: +86.755.2714.1166 ets.sales@lairdtech.com www.lairdtech.com AA-480-48-44-00-XX Outdoor Thermoelectric Cooler PERFORMANCE Pc VS ΔT 600 500 400 300 200 100 0 0 5 10 15 20 25 30 35 40 ΔT (°C) SPECIFICATIONS AA-480-48-44-00-XX Technical Technology Thermoelectric modules, forced air, closed loop (non-mixing), filterless, non-refrigerant 1 Cooling at ΔT = 0°C, and nominal / float voltage 480/529W (1638/1805 Btu/h) 2 Heating (calculated) 450W (1535 Btu/h) 6 Voltage (nominal / maximum) 48/60 VDC COP (Coefficient of Performance) 105% Grounding (all voltages) Positive or negative Current draw, ±10% (nominal / startup) 9.7/13.1 A Weight 13.2 kg (29.1 lbs) Panel mounting Through (from external side) Fan life (L10 at +40°C) Cold side 57,500 hours Hot side 75,000 hours Number of connectors 1 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 IP68 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.

The TE assembly must be mounted in a cabinet with “Hot side”  mounted externally.   2. Suitable cabinet cutout is 310x284 mm. 3. Recommended for general purposes: the TE assembly should be fastened according to picture below so that the gasket material will seal off around  the flange of the assembly.  4. The TE assembly is recommended to be positioned with "Cold side" in vertical direction with wires facing downwards (heat sink fins in vertical direction). 280                                                                                                                    306 5. Note that condensation may occure. Standing water on the heat sink 280                                                                                                                    306 330 should be avoided and drip tray may be required. 330 6. The TE assembly must be protected from external force or violence. 7. The power line to the assembly needs to be protected by a fuse. The fuse rating   should be of at least the nominal current of the assembly. It must withstand 150% of rated current for at least 60 seconds. This is valid at Ta=35°C. Fuse ratings for other am bient temperatures (x°C) can be calculated with the formula I[x°C]=I[35°C]/(1+0. 005*(x-35)). This is valid when regulating with an ON/OFF regulation. At rapid temperature cycling where this is applicable, there can be need for even higher fuse ratings. 8. Max ripple on supplied power =5%. MOUNTING HOLE LOCATION & HARDWARE 9. Switching power to TEM:s at frequencies between 0.01 Hz to 5 kHz will render premature failure of modules and must be avoided.   330 Service: 330 96 Fan impellers and heat sinks must be cleaned on regular intervals to reduce Φ5.5 (8x) risk for overheating and reduction of cooling function. The interval may vary Sealing gasket 96 depending on environment.
