The Opt Lasers Temperature Controller TEC-20A-25V-PID-H is an advanced Thermoelectric Cooler (TEC) controller, equipped with a microprocessor unit and mounted on a compact heat sink. This controller operates in a cooling mode, which enhances efficiency and minimizes the size of the board. It is compatible with Peltier modules that have currents up to 20 A.

The controller employs a PID algorithm and PWM modulation for current control, which helps to avoid extra heat dissipation on the MOSFET. It features a two-layer board with wide paths, and connectors that allow a maximum current of 13 A. For larger Peltier modules, it is suggested to directly solder into the PCB board.

This controller can accept a power supply voltage range from 7 to 25 V, which facilitates parallel or series connection of TECs. The stabilization temperature range of this controller can be adjusted according to specific needs. It is advisable to use power cables with a minimum cross-section of 1 mm². The maximum current that can flow through the board is dependent on the Peltier module used.

It is important to monitor the MOSFET temperature, which should not exceed 70 °C. To ensure proper cooling of MOSFETs, an additional fan may be required.
