A high quality universal input power supply with 12 V dc, 1.25 A output.
This power supply can be used to power the RAPIX DALI-2 Zone Controller and RAPIX DALI Ethernet Interface.
We suggest power supplies are loaded to no more than 80% of its capacity – this allows a little headroom, for example to handle peak currents when a load starts. Therefore, use a maximum of around 1 A of active load currents.
Pay attention to peak (start-up) currents and try to avoid exceeding 80% of the rated capacity.
For example:
| Product | Power | Number | Total Power | OK |
|---|---|---|---|---|
| Zone Controller | 200 mA | 4 | 800 mA | YES |
| Ethernet Interface | 100 mA (active) 200 mA (peak) | 5 | 500 mA (active) 1 A (peak) |
YES |
| Zone Controller + Ethernet Interface | 200 mA + 200 mA (peak) | 2 + 2 | 600 mA (active) 800 mA (peak) |
YES |
| Zone Controller + Ethernet Interface | 200 mA + 200 mA (peak) | 3 + 1 | 700 mA (active) 800 mA (peak) |
YES |
| Zone Controller + Ethernet Interface | 200 mA + 200 mA (peak) | 1 + 3 | 500 mA (active) 800 mA (peak) |
YES |
| Zone Controller + Ethernet Interface | 200 mA + 200 mA (peak) | 2 + 4 | 800 mA (active) 1200 mA (peak) |
NO
(Marginal / Excessive start-up current) |
