Which device is right for you?

The SAX Power Manager is available in two versions—both are installed by an electrician, but differ in installation effort and range of functions.

Power Manager Pro Mounted on the DIN rail in the distribution board—the full-featured solution with the maximum range of functions. Ideal for new installations or comprehensive energy management systems.

Power Manager Plug-In More compact and quicker to install than the Pro—the Power Manager Plug-In impresses with its straightforward installation. The range of functions depends on the current compatibility list.

Both versions can be conveniently controlled via app or browser and form the basis for true energy management in your own home.
