MFG Part Number AA-150-48-44-00-XX # AA-150-48-44 ## Outdoor Cooler Series Thermoelectric Cooler Assembly The AA-150-48-44 is an Air-to-Air thermoelectric cooler assembly that uses impingement flow to transfer heat. It offers dependable compact performance by cooling objects via convection. Heat is absorbed and dissipated through high density heat exchangers equipped with air ducted shrouds and brand name fans. The heat pumping action occurs from custom designed thermoelectric modules that achieve a high coefficient of performance (COP) to minimize power consumption. This model 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. ![Product image](/thermal-wizard/images/tea/Outdoor%20Cooler%20Series/AA-150-48-44/AA-150-48-44-large.png) ### Features - Wide operating temperature range from -40°C to +55°C - Telcordia GR-487-CORE tested and verified by customers when integrated in telecom outdoor enclosures - Environmentally friendly solid-state operation - No compressor or CFC refrigerants - Optional bi-polar thermostatic control ### Applications - [Enclosure Cooling](/applications/telecom/enclosure-cooling) - [Cooling for Mobile Base Stations and Cell Towers](/resources/application-notes/cooling-mobile-base-stations-and-cell-towers) - [Thermoelectric Cooling for Outdoor Kiosks](/resources/application-notes/thermoelectric-cooling-outdoor-kiosks) - [Thermal Management Solutions for Beverage Cooling](/resources/application-notes/thermal-management-solutions-beverage-cooling) - [Energy Storage Systems](/resources/application-notes/energy-storage-systems) ![Isometric drawing](/thermal-wizard/images/tea/Outdoor%20Cooler%20Series/AA-150-48-44/AA-150-48-44-isometric-drawing.png) ![](/thermal-wizard/images/tea/CE-ROHS.png) ### Specifications Heat Transfer Mechanism, Cold Side Air - Forced Convection Heat Transfer Mechanism, Hot Side Air - Forced Convection Temperature Range (External Ambient)1 -40°C to 55°C Temperature Range (Internal Enclosure) -20°C to 55°C Supply Voltage 48.0 VDC nominal / 56.0 VDC maximum Current Draw 3.9 A running / 5.0 A startup Power Supply 190.0 Watts Performance Tolerance 10% Hi-Pot Testing 707 VDC Fan MTBF 70000 hours Heating2 150 W Over-Temp Thermostat (Hot and Cold Side Heat Sink) 80°C ± 3°C Sound Level (1 m distance) 58 dBA Degree of Protection (Unit Internal Side) IP54 Degree of Protection (Unit External Side)3 IP54 Connector Type (On Unit) AMP part number: 350777-1, 794269, 350547-6, 794270-1 Connector Type (Mating Side) AMP part number: 350778-1, 350550-6, 794270-1 Weight 5.10 kg Panel Mounting Through ### Mounting Hole Location ![Mounting Hole Location](/thermal-wizard/images/tea/Outdoor%20Cooler%20Series/AA-150-48-44/AA-150-48-44-mounting.png) ### Wiring Schematic ![Wiring Schematic](/thermal-wizard/images/tea/Outdoor%20Cooler%20Series/AA-150-48-44/AA-150-48-44-wiring-schematic.png) ### Electrical and Thermal Performance **Optimum COP** Cooling Power (Qc) = 36.95 Watts TEM Voltage = 28.33 Volts TEM Current = 1.83 Amps TEM COP = 0.71 Power Supply = 51.8 Watts Power Dissipated (Qh) = 88.76 Watts Fan Voltage = 48.0 Volts Fan Current = 1.1 Amps **Maximum Qc** Cooling Power (Qc) = 89.21 Watts TEM Voltage = 56.14 Volts TEM Current = 3.79 Amps TEM COP = 0.42 Power Supply = 212.8 Watts Power Dissipated (Qh) = 302.0 Watts Fan Voltage = 48.0 Volts Fan Current = 1.1 Amps #### Default Calculated Operating Conditions ##### Electrical Operating Point - TEC Voltage: 48 V - TEC Current: 3.23 A - Cooling Power (Qc): 78.9 W - Power Supply: 154.95 W - TEC COP: 0.51 - Power Dissipated (Qh): 233.85 W - Fan Voltage: 48 V - Fan Current: 1.1 A ##### Thermal Operating Conditions Mode: Cooling - Ambient High Temperature: 35 °C - Control Temperature: 20 °C - Cooling ΔT: 15 °C ### Notes 1 Controller function shall not operate the external fan during heating mode. 2 Heating capacity is rated at external temperature of -40°C, nominal voltage, and dT = -45°C. 3 The highest environmental protection level NEMA 4 (IP55) requires an external shroud and is defined as the protection level for the enclosure.
