Rule of thumb
The following rule of thumb can be applied to calculate the number of power supplies required: a maximum of 24 modules
inside the electrical cabinet and a maximum of 70 controls (of which 20 with status LED) per power supply. Depending on
the size and layout of your installation, you will need to install one, two or three power supplies.
This rule of thumb leaves a considerable margin for error.
Exact calculation
Each control and module consumes a specific amount of energy. This consumption is expressed in points. One power
supply is needed for every 800 points. Add the points of all the controls and modules of your installation and divide this
sum by 800 to determine the number of power supplies required. A maximum of three power supplies can be used per
installation.
Calculate the exact number of power supplies required based on the table below.
