Model TC-24-10 Temperature
Controller
![[THE TC-24-10 TEMPERATURE CONTROLLER]](images/tc24-10.jpg)
APPLICATION
The TC-24-10 is a proportional-integral (PI) temperature controller
developed for equipment manufacturers requiring a low cost device. The
TC-24-10 will operate a thermoelectric module in either a cooling mode or
a heating mode.
TECHNICAL DESCRIPTION
Power to the thermoelectric module is delivered via a 400 Hz
Pulse-Width-Modulated (PWM) output. This methodology will not reduce the
thermoelectric module's reliability due to thermal cycling (as can some
other on-off controllers). The PWM design also allows the controller to
power thermoelectric systems of up to 24 volts and 7 amps without an
external heatsink. Adjustments for setpoint, proportional gain, and
integral gain are made via trimpots located on the printed circuit board.
These trimpots can be replaced with fixed value resistors for large volume
applications thus negating the need to adjust each controller
individually.
The TC-24-10 comes with one MP-2379 thermistor. If you would like to
purchase additional thermistors, please indicate when ordering.
