Oven Industries’ Model 5R7-388 RoHS-compliant controller is a bi-directional control for independent thermoelectric modules, or can be used 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 RS232 communication port for direct interface with a compatible PC. The communications link permits a variety of operational mode configurations. Field selectable parameters or data acquisition in a half duplex mode can be performed. This controller will accept a communications cable length in accordance with RS232 interface specifications. Once the desired set parameters are established, the PC may be disconnected and Model 5R7-388 becomes a stand-alone controller. All parameter settings are retained in non-volatile memory.
