About the TEC-20A-30V Temperature Controller
The TEC-20A-30V is a simple TEC controller that features analog elements and a small PCB board. With its high operating currents, this driver is suitable for a wide range of applications. Achieving a temperature stabilization accuracy of ±0.4 degrees Celsius, this device combines high current capabilities, a broad voltage range, and high precision within its compact 16.5 x 25.5 mm footprint. Operating exclusively in cooling mode, this driver incorporates voltage feedback from an NTC thermistor for optimal performance.
With a two-layer board and wide paths, it supports Peltier modules with currents up to 20 A, while connectors enable a maximum current of 13 A. For larger Peltier modules, direct soldering into the PCB board is recommended. The controller accepts a power supply voltage range of 7 to 25 V, allowing for parallel or series connection of TECs.
Peltier modules can be connected in series or parallel. Proper wiring with larger cable cross-sections is necessary for high current applications.
Recommendations and requirements
- We recommend the use of power cables with a minimum cross-section of 1 mm2.
- We highly recommend utilizing an NTC 10k sensor for optimal performance.
- The maximum current flowing through the board depends on the Peltier module used, which can be determined from their labels (e.g., 12704 represents 12 V and 4 A, 12715 represents 12 V and 15 A).
MOSFET temperature should be monitored and can not exceed 70 degrees Celsius.
The MOSFET must be isolated from the heatsink/plate using a silicone pad, and a plastic sleeve (included). A short circuit between the MOSFET and heatsink/plate can potentially damage the driver and pose a danger to the device.
