Abstract

The invention relates to an emergency electrical power supply system, for example for supplying electrical power to signal illumination and safety illumination, which system has a battery unit (1), means (2) for switching over the electricity supplied from the battery unit (1), and a group control centre (3) for supplying the electricity to loads. In order to create redundancy of the switching means in a manner which is as simple and advantageous as possible, it is provided according to the invention that the means (2) for switching over the electricity supplied from the battery unit have a plurality of changeover modules (2a, 2b ..., 2n), which are connected in parallel on the side of the battery unit (1) and whose outputs are coupled to one another only by means of their neutral lines, while the phase conductor of the output of each changeover module (2a, 2b, ..., 2n) is arranged for supplying a plurality of loads and one group (3a, 3b, ..., 3n) of the group control centre (3) with electricity. The changeover modules (2a, 2b, ..., 2n) are preferably identical to one another. <IMAGE>
