Outdoor cooler uses bi-polar thermostatic control

The AA outdoor cooler series is a ruggedised 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 inside the TEA to maintain its tight form factor.

The unit is available in two of Laird's most popular set-point configurations.

The LK-81 is programmed to cool when the internal of the enclosure exceeds 25C and heat when it drops below 10C.

Products in this series are offered in four models: AA-150-24-44-LK-XX - 150W capacity, 24V operation; AA-150-48-44-LK-XX - 150W capacity, 48V operation; AA-200-24-44-LK-XX - 200W capacity, 24V operation; and AA-200-48-44-LK-XX - 200W capacity, 48V operation.

The LE-80 is programmed to cool when the internal temperature of the enclosure exceeds 35C and heat when it drops below 5dC.

Products in this series are also offered in four models: AA-150-24-44-LE-XX - 150W capacity, 24V operation; AA-150-48-44-LE-XX - 150W capacity, 48V operation; AA-200-24-44-LE-XX - 200W capacity, 24V operation; and AA-200-48-44-LE-XX - 200W capacity, 48V operation.

This product series has been designed to pass rigorous Telcordia test requirements conducted by Laird Technologies' customers, such as earthquake resistance, salt fog, wind-driven rain, high-temperature exposure and dust contaminants.

This is due to the selection of components such as brand fans with a high degree of environmental protection, heavy-duty anodisation on the high-density heat sinks, lifetime guaranteed waterproof connectors, overheat protection and double environmental seals for the thermoelectric modules (TEMs).
