The TC-24-10 is a RoHS compliant proportional-integral (PI) temperature controller developed for applications requiring a low cost, basic temperature controller. Set-point and tuning adjustments are made via potentiometer. It can modulate power from 9V up to 26 V at currents up to 10 A when using a single power supply. The controller can also modulate from 0 V up to 50 V when using two power supplies, making this a good choice for controlling low-voltage modules. As with all of our controllers, a standard temperature sensor (15K thermistor) is included. Labeled wiring cables are included free of charge when purchasing interconnected standard products on the same order (thermoelectric cooling assembly or module, temperature controller and/or a power supply). The number of cables included (1-3 pairs) will depend on the number of components being interconnected.

APPLICATION
The TC-24-10 provides cool-only or heat-only temperature control for thermoelectric devices. A jumper on the printed circuit board selects cooling or heating control. The controller uses single solid-state MOSFET device to modulate the thermoelectric device current based on the temperature set point. This methodology does not induce thermal cycling and so will not affect the thermoelectric module reliability as can on-off controllers.
Adjustments for set-point, proportional gain, and integral gain are made via variable resistors (potentiometers) located on the printed circuit board. These adjustment values can be pre-programmed into the controller for large volume applications thus negating the need to adjust each controller individually.
Mechanically, the controller’s printed circuit board is mounted to a metal bracket that is suitable for either horizontal or vertical orientation. The controller can operate in ambient temperatures from 0 C up to 50 C without generally requiring additional heat sinking.
TECHNICAL DESCRIPTION
-
Low voltage TE device control capability. The TC-24-10 requires an input voltage anywhere from 9 V up to 26 V. That voltage powers the microprocessor and can also be modulated and sent to the thermoelectric device. However, if the thermoelectric (Peltier) cooler operates on a voltage lower than 9 V or higher than 26 V, a second power supply can be connected. The controller can then modulate power from the second supply, and the second input voltage can range anywhere from 0 V up to 50 V.
-
General purpose resolution and stability. The output signal to the thermoelectric cooler is pulse-width modulated (PWM) at 1000 Hz. The PWM control scheme affords temperature resolution of 0.15 C and controller stability typically as good as 0.50 C. The controller is best suited for applications where there is a general need for temperature control but where high precision and control are not needed.
-
Accepts TE Technology’s standard 15 K thermistors. The controller comes with a standard lug-mount 15k thermistor which provides a control temperature range of -20 C to 100 C. TE Technology offers other 15 K thermistors in different mechanical packages, and these can also be used in place of the standard thermistor.
- Protected output stage. The output transistor (MOSFET) is thermally protected in case of inadvertent overheating. The transistor will switch the output off and then continually try to restart itself until it can operate at a safe temperature.The TC-24-10 comes with one MP-3238 thermistor, which is slightly different than the one pictured above. It is a 15K thermistor mounted in an aluminum block–essentially an MP-3193 thermistor (shown on the thermistors page) but with quick connects on the wires for attachment to the TC-24-10.SPECIFICATIONS
