Model TC-24-10 Temperature Controller

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.
