Product Overview:

The WTC3243 is known for its precision, stability, and versatility.

It is a compact, analog PI (Proportional, Integral) control loop circuit optimized for use in ultrastable thermoelectric temperature control applications. It easily handles variable operating conditions with a stability of better than 0.0009ºC.

The WTC3243 is a linear temperature controller that delivers bidirectional current to Peltier Effect thermoelectric coolers (TEC), or unidirectional current to resistive heaters.

The temperature setpoint is set by a remote voltage signal capable of controlling both thermoelectric and resistive heaters, and only five external resistors are needed to optimize the controller for your specific applications.

The WTC3293 Evaluation Board is available to quickly integrate the WTC3243 into your system and can be optimized for sensor type. You can use the adjustable trimpots to configure heat and cool current limits, proportional gain, and integrator time constant.

The WTC3243 has a built-in safety to protect the device. The heat and cool limits can be set independently. The safety feature guarantees that your thermoelectric cooler will never be driven beyond your specified limits.

The robust and reliable WTC3243 has leading-edge applications designed into electro-optical systems, airborne instrumentation, spectroscopic monitors, and medical diagnostic equipment. It is specifically well-suited to applications where the temperature is scanned across ambient.
