It depends on the power supply. With the power supply in the track, we are limited by the power of 150W. With external power supply, we are limited by the power of the power supply used, but it is not recommended to use too long rail lines. The length of the track circuit is limited by the number and power of the luminaires. For this reason, it is recommended to divide the luminaire line into smaller sections of max. 20 meters with independent power supplies.
Remember to leave about 20% power reserve on the power supply. In the Shift 2F System, the power that can be used on the rail applies to one circuit, e.g. 2x150W.
