The Bi-directional or unidirectional H-bridge configuration of Oven Industries’ temperature controller creates a seamless transition between heating and cooling as it commands the thermoelectric modules. The included user-friendly PC software makes it easy for the user to change control configurations through the RS-232 or RS-485 interface which has 1.5 kVac isolation from the electronic circuitry virtually eliminating interference from noise or errant signals. Once the temperature controller is set-up, the computer may be disconnected and the temperature controller becomes a standalone unit or the computer can remain connected for data acquisition. The load circuit is pulse width modulated at 2.7 kHz and delivers a load current of 0.1A to 25A.
