This is an advanced TEC controller using micro processor unit.
Thanks to PID algorithm additional heat is not dissipated on the mosfet since driver uses PWM modulation for current controlling.
Due to the fact that the driver is working in cooling mode, it was possible to use fewer elements, make the board smaller and improve the overall efficiency.
Thanks to a two layer board and wide paths it is possible to use TECs with up to 20A. Connectors allow to use maximum current of 13A so if there is a need to use bigger Peltier cells, wires should be soldered directly into the driver's PCB board.
Driver can be powered from 7 to 25V voltage range what allows to join TECs parallel or in series. Please remember that high current needs proper wiring with bigger cross section of the cables.
Maximum current flowing through the device depends on TEC used. Voltage dropout on a driver is very small so current can be predicted by reading TEC labels.
For example 12704 means 12V and 4A. 12715 means 12V and 15A.
It is possible to change stabilisation temperature range, please write us an email if needed.
Recommendations and requirements
We recommended the use of power cables with minimum cross-section of 0.5mm2.
The MOSFET must be isolated from the heatsink/plate with silicon pad as well as plastic sleeve (included). Short circuit between MOSFET and heatsink/plate can damage the driver and can be dangerous for the device.
Mosfet temperature should be monitored and it can not exceed 70 degrees Celsius.
