As a thermoelectric module bench-top temperature controller with its own power supply, the self-contained, singly enclosed 5R6-900 unit from Oven Industries can be plugged into the wall and accessed from anywhere. The solid-state MOSFET bidirectional compact bench-top unit features an internal power supply and is capable of loading currents up to 10 A. User-friendly and PC programmable, the unit connects through the electrically isolated RS232 communications port. The PC can be used as a connector, and the temperature controller can stand alone once the desired parameter settings are in place. Settings are stored in the nonvolatile memory. The temperature controller features a digital display for adjusting output voltage and for setting the temperature. Other features include an auto output shutdown; high, low, and no alarm settings; and a compact size.
