AC-220 Peltier-Thermoelectric Air Cooler
•
Ideal for medium to large electronics enclosures or refrigeration applications where a
large temperature difference is not required.
•
NEMA 4 protection: anodized external fins, environmentally sealed IP68 external fan,
and stainless steel finger guards.
•
Large cooling capacity in a compact size: 350 mm length x 150 mm width x 185 mm
thickness.
•
Removes 214 W of heat in a 32 °C ambient at a 0 °C temperature difference.
•
Internal fan blows air into the center of the enclosure so you can aim cooled air at
components that need the most cooling.
•
Heats as well as cools (when used with heat & cool / bipolar controller).
•
High quality dual ball bearing fans for long life; external fan is speed controllable and
has tachometer output.
•
Can easily be customized for production sized orders to meet your exact
requirements.
•
Includes integral thermostats (signal level) for over temperature protection using
power supply inhibit lines or temperature controller interlock features.
•
CE marked, RoHS compliant.

Example: You need to maintain the enclosure at 40 °C while in a 50 °C ambient. The cooler can remove a maximum of
approximately 175 W of heat from the enclosure. If the heat load (internally generated heat plus the heat gain through
insulation, solar, vapor condensation, etc.) in the enclosure exceeds this, you would need more coolers and/or a larger
cooler.

Example: You need to maintain the enclosure at 30 °C while in a -20 °C ambient. The cooler can add up to

Two thermostats are wired in series and
terminated at positions

2. One is
mounted mounted internally on the heat sink
and one externally on the cold sink. The
thermostats are normally closed, open at 75
°C +/-5 °C, and automatically reclose at 60 °C
+/-7
°C. These can be wired to a power
supply’s remote switch or the TC-720
temperature controller’s interlock to shut off
output power in the event of an over-
temperature condition. The electrical contacts
are rated for SIGNAL LEVEL ONLY.
Contacts are gold-plated silver. DO NOT
