This new control is capable of controlling two separate circuits independently. Like the PowrTrol, the PowrTwin is a solid-state, proportional-voltage controller that allows the precise manual control of laboratory heating equipment such as heating tapes, heating cords, and heating mantles. The PowrTwin has an output range adjustable from 3-100% of rated voltage. The PowrTwin can be used on the bench top, or it can be mounted to lattice work using the clamp provided. Wattage: 840 per circuit, 7 Amp per circuit.
