DESCRIPTION
The AE Water-Cooled Stack provides a water-cooled thyristor pair for high-power applications.
The unit can be controlled by the Thyro-PX power controller. If optical isolation between the power
controller and the stack is needed, you can use the electrical to optical interface and optical to
electrical interface boards.

The switch contacts are rated at 250 V, 10 A, and open at 85°C (185°F). For installations operating at greater than 250 V AC, use the heat-shrink tubing supplied with the unit to double insulate the temperature switch wires.
