Open board temperature controller
An open board temperature controller designed with a proportional integral control algorithm, to provide the most precise control to thermoelectric (Peltier effect) modules, has been released by Oven Industries.
The H bridge control provides a seamless transition between heating and cooling, eliminating dead spots. A red LED for heat and green LED for cooling indicate mode.
Pulse width modulation controls the power level in the thermoelectric module at a base frequency of 900Hz. Power resolution is one of ±255 steps in the load circuit control.
The unit features solid state H-bridge control, bidirectional control (seamless transition) and TTL to USB communication via optional OI-TTL-cable.
Oven Industries supplies custom temperature controllers and sensors that serve a range of industries.
