Universal Input Power Supply, 12 V dc 1.25 A

A suitable third-party universal-input 12 V dc power supply, stocked for convenience — for example to power the RAPIX DALI-2 Zone Controller and RAPIX DALI Ethernet Interface.

Controllers and interfaces only need a regulated 12 V SELV supply of adequate current. If you already have a suitable 12 V source, you can use that; we stock this unit when you need one.

Exact brand and model of current stock may change. For design purposes we guarantee 1 A at 12 V (some stocked units are higher-rated). Typical of current stock is a compact DIN-rail form factor. Contact us if you need to confirm dimensions or the exact unit currently supplied.

Power supply sizing

We recommend staying below 80% of available current. For our supply, that means about 800 mA (we guarantee 1 A at 12 V).

Zone Controllers and Ethernet Interfaces: budget 200 mA each. Count how many you have on the same 12 V rail, multiply by 200 mA.

Example	Devices	Budget	Fits this PSU?
Four Zone Controllers	4 × 200 mA	800 mA	Yes
Three Zone Controllers + one Ethernet Interface	4 × 200 mA	800 mA	Yes
Five Zone Controllers / Interfaces (any mix)	5 × 200 mA	1 A	Not recommended — no start-up headroom; prefer a second supply so each rail stays within 800 mA
Six Zone Controllers / Interfaces	6 × 200 mA	1.2 A	Split across two of supplies (or contact us for larger installs)

Not a fit for this PSU (use the adapter that ships with the product):

10.1″ touch panel	Typical draw about 19 W (~1.6 A at 12 V); ships with a 50 W adapter.
