The HPreTC-10 is a high precision temperature controller capable to control TEC elements in order to maintain a constant temperature of different loads e.g. laser diode.

The HPreTC-10 is a compact non-isolated DC/DC switch mode power supply with bidirectional current output. Controller contain a closed loop amplifier with adjustable settings P (proportional), I (integral) and D (differential) share for providing optimal temperature regulation.

HPTC-100 can be controlled by CAN interface with PC software.

Controller is designed to maintain temperature based on feedback provided from a 10 kΩ NTC type thermistor sensor.
