PowerCool Series Thermoelectric Cooler Assembly
The DA-280-24-02 is a Direct-to-Air Thermoelectric Cooler Assembly that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via conduction. Heat is absorbed through a cold plate and dissipated thru a high density heat exchanger equipped with an air ducted shroud and brand name fan. It has a maximum Qc of 283 Watts when ΔT = 0 and a maximum ΔT of 45 °C at Qc = 0.

You can interact with the Performance Curves below to estimate the cooling performance by entering the thermal and electrical operating conditions for your application.
