The AP2003 can supply power to several AEOS modules simultaneously. The maximum number depends on the type of module and the peripherals that are connected. The voltage supplied to peripherals, such as locks and sensors, can be precisely adjusted to match the connected modules (5V, 12V or 24V). The table on the next page will help you to calculate the power consumption for the configuration you require. Make sure you include all external power consuming appliances in the calculation. It is further possible to link a number of AP2003s in series (see AP2003 Installation Manual).
