PRECISION, STABILITY & VERSATILITY
The WTC32ND 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 temperature setpoint is set by a remote
voltage signal. It is capable of controlling both thermoelectric
and resistive heaters, and only five external resistors are
needed to optimize the controller for your specific application.
The WTC32ND-EV Evaluation Board is available to quickly
integrate the WTC32ND into your system and can be
optimized for sensor type. Use the adjustable trimpots to
configure heat and cool current limits, proportional gain, and
integrator time constant.

BUILT-IN SAFETY
To protect the device, heat and cool limits can be set
independently. This safety feature guarantees that your
thermoelectric cooler will never be driven beyond your
specified limits.
LEADING EDGE APPLICATIONS
The robust and reliable WTC32ND has been designed
into electro-optical systems, airborne instrumentation,
spectroscopic
monitors,
equipment. It is particularly well-suited to applications
where temperature is scanned across ambient.
