WTC3243 2.2 A Temperature Controller, Wavelength Electronics, Inc. (CAT#: STEM-LE-1998-LC)

The WTC3243 temperature controller with compact design achieves a temperature stability of 0.0009°C. Its software package can be integrated with heat sink WHS302,thermal washer WTW002 and fans WXC303 (5 V) or WXC304 (12 V) to facilitate prototyping. The linear PI control loop provides maximum stability, while the bipolar current source is designed to increase efficiency. The WTC3243 is a thermoelectric (bipolar) or resistive heater (unipolar) driving current of up to 2.2 A. The evaluation board can simplify the prototype design: WTC3293. WTC3243HB is compatible with lithium-ion batteries.
