5R7-002 THERMOELECTRIC CONTROLLER
The Bi-directional or unidirectional H-bridge configuration of this 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 RS485 interface which has 1500VAC isolation from the electronic circuitry virtually eliminating interference from noise or errant signals. Once the controller is set-up, the computer may be disconnected and the controller becomes a stand alone unit or the computer can remain connected for data acquisition. The temperature may also be set through the optional display or remote potentiometer. The load circuit is pulse width modulated at 2.7Khz and delivers a load current of .1 to 25 Amps.
