Description

A high quality universal input power supply with 12 V dc, 1 A output.

This power supply can be used to power the RAPIX DALI-2 Zone Controller and RAPIX DALI Ethernet Interface.

Power Supply Sizing Chart

We suggest power supplies are loaded to no more than 75% of its capacity – this allows a little headroom, for example to handle peak currents when a load starts. Therefore, use a maximum of 750 mA of active load currents.

Pay attention to peak (start-up) currents and try to avoid exceeding 80% of the rated capacity.
