PC programmable via RS232 communication port, Model 5R7-388 offers control range of -328 to 500°F. RoHS-compliant unit is used for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for both cooling and heating applications. H-Bridge configuration of solid state MOSFET output devices allows for bi-directional flow of current. Once desired parameters are set, PC may be disconnected and Model 5R7-388 operates as stand-alone controller.
