The AC-220 provides high cooling capacity in a narrow 150 mm wide (5.9″) package. The overall dimensions are compact making it easy to get significant cooling capacity in a small space. The cooler is powered by 24 VDC and is rated to maintain the enclosure’s NEMA 4 rating. The AC-220 is protected against harsh environments via an anodized external heat sink, stainless steel hardware, and an IP-68 rated external fan. The external fan is also speed controllable and has a tachometer output signal. Like all cooling assemblies from TE Technology (and unlike many coolers from competitive companies) the thermoelectric/Peltier elements have our epoxy potting and the assembly is sealed to reduce moisture ingress inside the cooler.
The AC-220 can also be used for heating, and two over-temperature thermostats are incorporated in the cooler (one on each set of fins). The thermostats are intended to provide a separate means of over-temperature protection for the cooler and equipment and can be monitored via the interlock feature on a TC-720 temperature controller or used to control the output inhibit line on a PS-24-25 power supply. Please note these thermostats are NOT intended as a means of temperature control for the cooler or for direct switching of high-current loads.
Finally, as with all TE Technology coolers it can also be customized with other features if production quantities are needed.

TC-48-20 OEM
$311.00 Add to cartProduct DetailsThe TC-48-20 OEM has the same control capabilities as the TC-48-20 but leaves off the keypad, display interface, and housing to keep costs to a minimum. The controller can be connected to a computer via an optional RS232 serial cable and used with the included software to provide program control as well as data graphing and data logging. The software is shipped as a stand-alone program, but the LabVIEW source code (version 2011 and higher) is also available upon request and a sample read and write command programmed in Python is also available for download.

TC-36-25-RS232-UL
$689.00 Add to cartProduct DetailsThe TC-36-25-RS232-UL has the same features as the TC-36-25 RS232, including bi-polar (heat and cool) proportional-integral-derivative control that can modulate input voltages of up to 36 V at currents of up to 25 A. This version is CE marked and is MET-Labs listed, conforming to UL 60730-1. Due to listing requirements the controller does not come with a temperature sensor (thermistor) or RS232 cable, but these can be ordered separately. Windows-compatible, LabVIEW-based GUI software is available as a download, the LabVIEW source code is available free of charge upon request, and a sample read and write command programmed in Python is also available for download.

TC-48-20
$506.00 Add to cartProduct DetailsThe TC-48-20 is an easy to use yet powerful cool-only or heat-only PWM temperature controller. It is housed in a die-cast aluminum box, incorporates a keypad and display, and is capable of controlling from 0 to 50 volts and up to 20 amps. Two versatile alarm outputs are included, each capable of switching up to 1 amp of current. If a true linear-output control system is desired (for applications extremely sensitive to electrical noise) the TC-48-20 can be used as the control head for high-power, variable-output linear supplies. Most control parameters can be programmed via the built-in keypad, but the controller can also be connected to a computer via an optional RS232 serial cable for more advanced program control as well as data graphing and data logging. The software is shipped as a stand-alone program, but the LabVIEW source code (version 2011 and higher) is also available upon request and a sample read and write command programmed in Python is also available for download.
