• Thermoelectric Controller

  • The triple Peltier temperature controller is capable of distributing power to between one and three thermoelectric elements in a stacked configuration.  The controller attempts to maintain a preset temperature by switching current to the thermoelectric elements in a forward or backward direction when the temperature drifts outside of a preset range.  The bi-directionality of the current switching allows control of thermoelectric elements in a heating or cooling capacity.  The controller is also capable of switching DC electric heaters (or refrigerators) in a one-sided mode of operation.
