mCTRL-T-20-12/55 mini TEC Controller

Max. Output Current TEC 20 A; Chassis Mount; Supply Voltage 12-55 VDC; Temperature Stability <0.1°C; H-Bridge Control; Temperature Regulation PID or ON/OFF

AMS Technologies‘ mCTRL-T-20-12/55 mini TEC controller uses an electrical H-bridge to drive thermoelectric coolers (TECs) / Peltier elements with broadly variable voltages und currents of up to 10 A, or up to 20 A using a heat sink. An auxiliary temperature sensor (RTD such as Pt100, Pt1000, or thermistor) can be connected to allow highly accurate temperature control within less than ±0.1°C.

The user can select a set temperature between -100°C and +100°C via analog interfaces such as 0-5 V or 4-20 mA, or digital interfaces like RS232 (serial) or WiFi. The layout of the board allows to separate the graphic OLED display, including the device’s three control buttons, enabling OEMs to separate this display/control unit from the main board and connect it to the main board via ribbon cable.
