The new 5R6-900 thermoelectric module bench-top temperature controller unit is contained in one enclosure. This means the device can be plugged into the wall as a convenient and self-contained temperature control system, with its own power supply. It can also be used universally, which allows the user to access the device wherever they are located. As a solid-state MOSFET bidirectional compact bench-top unit featuring an internal power supply, it is also capable of loading currents up to 10A. User-friendly and PC programmable, the unit easily connects to a computer through the electrically isolated RS232 communications port. Oven Industries
