The Domus DRIVER-12V-IP67 is an outdoor non-dimmable 12V DC constant-voltage LEDdriver IP67, in nine wattages from 20W to500W, with 1m flex and plug.

Nine sizes, 20 W to 500 W the widest range in this catalogue

• 20 / 30 / 60 / 100 / 150 / 200 / 300 / 400 / 500W, chosen from thedropdown.
• Our record lists 20W, the smallest. It is not isolated: of 22 Domusproducts whose variants are wattages, 18 record only the smallest.
• The 300500W sizes are what make this a commercial part. A 500W12V driver runs a very substantial garden installation from one point but at12V, 500W is over 40A, which is a serious cable calculation rather than adetail.
• Above about 150W, splitting into several smaller drivers close to their loads usuallybeats one large driver at the origin shorter low-voltage runs, less volt drop, smallercable, and one failure does not take out the whole garden.
• Tell us the layout and the total load and we will work out whether one driver or several isthe better answer.

A wider working range than the dimmable version

• 15C more headroom at the top end is the figure that matters in Australia. Adriver in a garden enclosure in full summer sun can exceed 45C internally without the air beinganywhere near that.
• So in an exposed or unshaded position, the non-dimmable version is the more robustchoice and if dimming is not needed, that is a straightforward win.
• Neither listing compares them. The difference is only visible by reading bothdatasheets.

What IP67 gives you

• Dust-tight and rated for temporary immersion a genuineburied-in-a-garden-bed rating, not just a rain rating.
• Which is what the product is for: the datasheet names LED strip, ingrounduplighters and garden spike lighting.
• Temporary immersion is not permanent. A driver sitting where water stands afterevery storm will fail eventually. Mount it above the water line or in a drainedenclosure.

Protection, and the wiring rule

• Secondary-side short-circuit protection a low-voltage cable cut by a spadeshuts the driver down rather than damaging it. On a garden run, this is the feature that saves thepart.
• Thermal overload, over-temperature and over-voltage protection.
• Efficiency up to 89%; PF >0.95. 240g,150 44 32mm, 2090% RH non-condensing.
• Parallel wiring, never series.
• Size to the load with about 20% headroom. Running at the rated maximum shortensits life.

Two record entries worth knowing

• Its 5-year replacement warranty is in the datasheet prose and in no field. Five years is the longest term in this catalogue, and on a driver it is the term that matters most the driver is what fails first in a garden installation.
• application: Indoor on an IP67 driver made for garden beds. That field holdsIndoor on 340 of 342 Domus records. Read the IP67.

Where it works

• Garden lighting spikes, inground uplighters, exterior strip.
• Buried or ground-level enclosures, at IP67.
• Exposed and unshaded positions the +60C ceiling.
• Large installations, at 300500W subject to the cablecalculation.
• Not where dimming is needed use the dimmable version, and accept thenarrower temperature range.

Specifying it

Outdoor non-dimmable 12V DC constant-voltage LED driver. IP67. 20 / 30 / 60 / 100 / 150 /200 / 300 / 400 / 500W. Efficiency up to 89%, PF >0.95. 150 44 32mm, 240g.Working range 40C to +60C, 2090% RH non-condensing. Secondary-side short circuit,thermal overload, over-temperature and over-voltage protection. 1m flex and plug. Parallelwiring. Our record lists 20W, the smallest of nine variants, and calls this an indoor product. Its 5-year warranty is in the datasheet prose and in no field. Its working range is wider than thedimmable IP67 version’s.

Questions

Which wattage do I need?

Add up the load and allow about 20% headroom running a driver at its rated maximum shortens its life. Nine sizes are offered from 20W to 500W, which is the widest range of any product in this catalogue; our record lists only 20W, the smallest. One caution at the big end: at 12V, 500W is over 40 amps, which is a serious cable calculation rather than a detail. Tell us the layout and the total load and we will work it out.

Should I use one big driver or several smaller ones?

Above about 150W, several smaller drivers close to their loads usually beats one large driver at the origin. You get shorter low-voltage runs, less volt drop, smaller cable and importantly one failure does not take out the whole garden. A single 500W driver at the meter box feeding a long 12V run is the arrangement most likely to disappoint. Tell us the layout and we will suggest the split.

How is it different from the dimmable IP67 version?

Two ways, and one is not obvious. It does not dim, and its working range is wider: 40C to +60C against the dimmable version’s 30C to +45C. That 15C of extra headroom at the top end is the figure that matters in Australia a driver in a garden enclosure in full summer sun can exceed 45C internally without the air being anywhere near that. So in an exposed or unshaded position, if you do not need dimming, this is the more robust choice. Neither listing compares them.

Can I bury it in a garden bed?

IP67 is dust-tight and rated for temporary immersion, so yes that is genuinely a garden-bed rating rather than just a rain rating, and it is what the product is made for. But temporary immersion is not permanent: a driver sitting where water stands after every storm will fail eventually. Mount it above the water line or in a drained enclosure even at IP67.

What protection does it have?

Four things, all in the datasheet prose and none in a product field: secondary-side short-circuit protection, thermal overload, over-temperature and over-voltage protection. The short-circuit protection earns its keep in a garden a low-voltage cable cut by a spade shuts the driver down instead of damaging it, which is a far commoner event than people expect.

How do I wire the fittings to it?

In parallel, never in series each fitting connects across the same 12V output rather than one after another. Wiring low-voltage fittings in series is a common and expensive mistake: the voltage divides between them and nothing runs properly. If you are running several zones or a long line, tell us the layout and we will draw it with you.

What is the warranty?

Five years, stated in the datasheet prose as a replacement warranty and in no product field. It is the longest term in this Domus catalogue, and on a driver it is the term that matters most: the driver is what fails first in a garden installation and the fittings outlive it. On a buried or hard-to-reach run, the labour to replace one dwarfs the part. Ask us to confirm it with your order.
