PowerCool Series DA-280-24-02-00-00 A Direct-to-Air Thermoelectric Assemblies The PowerCool Series direct-to-air thermoelectric assembly is a high performance thermoelectric based heat pump. It is designed to temperature control small chambers used in medical diagnostics or sample storage compartments in analytical instrumentation. This unique design offers a high performance hot side heat dissipation mechanism that convects heat more efficiently than conventional heat exchanger technologies. The design utilizes custom thermoelectric modules to maximize cooling capacity and premium grade fans to reduce noise. Moisture resistant insulation is used to keep condensation from penetrating into the TEM cavity. This unit operates on 24 VDC and is designed for indoor lab use environment. Custom configurations available upon request.

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 as 150% of rated current for at least 60 seconds. This is valid at Ta=35°C. Fuse ratings for other ambient temperatures (X°C) can be ca 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 i need for even higher fuse ratings. Cooled parts need to be isolated from air humidity to minimize risk for condensation and thermally insulated for best performance Max ripple on supplied power =5%. Switching power to TEMs at frequencies between 0.01 Hz to 5 kHz will render premature failure of modules and must be avoided.
