AC-140

Capacity Rating: 139 watts at a 0°C temperature difference.
Example Applications: Electronic equipment enclosures, telecommunications equipment, and camera enclosures.
Features: Specially designed to remove heat from an enclosure while maintaining the internal temperature at or near ambient. Low power consumption and high efficiency yield low operating costs and make it a good choice when the power supply must be located inside the enclosure. It has a sealed fan, corrosion protection, and maintains an enclosure’s NEMA 4 rating. Can be used for heating and cooling. Compatible with all of TE Technology’s temperature controllers. Multiple units can be easily controlled by one temperature controller.

Features: Specially designed to remove heat from an enclosure while maintaining the internal temperature at or near ambient. Low power consumption and high efficiency yield low operating costs and make it a good choice when the power supply must be located inside the enclosure. It has a sealed fan, corrosion protection, and maintains an enclosure’s NEMA 4 rating. Can be used for heating and cooling. Compatible with all of TE Technology’s temperature controllers. Multiple units can be easily controlled by one temperature controller. Labeled wiring cables are included free of charge when purchasing interconnected standard products on the same order (thermoelectric cooling assembly or module, temperature controller and/or a power supply). The number of cables included (1-3 pairs) will depend on the number of components being interconnected.

• High efficiency design.
• Multiple units can be operated by one temperature controller.
• Can be used for heating and cooling (requires heat/cool controller).
• Protected against harsh environments –meets NEMA 4 and IP68 (fan) specifications.
• Removes 139 watts from an enclosure while maintaining internal temperature at ambient temperature.
• Low power consumption reduces operating costs and makes this cooler a good choice for applications where the power supply is located inside the enclosure.
• CE marked and RoHS compliant.

This cooler is specially designed for low power consumption and high efficiency. Its intent is to remove heat from an enclosure while maintaining the internal temperature at or near ambient–it is not typically used to achieve refrigeration temperatures.  So, this cooler is ideal for applications where the goal is to prevent an electronic equipment enclosure from overheating. It can, as with all of our coolers, both heat and cool when used with the proper temperature controller.

The low power consumption yields low operating costs and also means that the cooler’s power supply will generate less waste heat.  Thus, the power supply has less of an impact when it is located inside the enclosure.

The cooler is powered by 24 VDC and works with a wide range of temperature controllers. If you need more capacity, or need to distribute the cooling throughout larger cabinet, you can parallel multiple AC-140 coolers and have them all regulated by one temperature controller. The power input wires are routed on the cold side of the cooler and make it easy to connect the wiring from inside the enclosure. (As always care should be taken so that condensation is not allowed to form on the cold side heat exchanger where it could come in contact with the power wires.)

Finally, the AC-140 incorporates environmental protection.  The hot-side fan is sealed against moisture, the heat sink uses marine-grade anodizing to prevent corrosion, and the unit is rated to maintain the enclosure’s NEMA 4 rating.

Note:  Larger power supplies are used when controlling multiple units with one temperature controller.
