The Model 5R7-388 RoHS Compliant controller is a bi-directional control for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for both cooling and heating applications.
The "H" bridge configuration of the solid state MOSFET output devices allows for the bi-directional flow of current through the thermoelectric modules. Highly efficient N-channel output devices are used for this control mode. This controller is PC programmable via an RS-232C communication port for direct interface with a compatible PC. The easily accessible communications link permits a variety of operational mode configurations. Field selectable parameters or data acquisition in a half duplex mode can be performed. The controller will accept a communications cable length in accordance with RS-232C interface specifications. Once the desired set parameters are established, the PC may be disconnected and unit becomes a unique, stand alone controller. All parameter settings are retained in non-volatile memory.
