TRANSFO CREATOR
TRANSFORMATEURS SPÉCIAUX
Caravans and motorhomes use 12VDC equipment: water pump, refrigerator, heater, etc.
These appliances require a DC power supply, via a battery. However, for reasons of comfort, you may want to use the traditional 230V EDF mains supply, without using the battery.
To do this, you’ll need a 230V 12V power supply. We emphasise the term Power supply and not Transformer: A power supply converts AC current into DC current. A transformer, on the other hand, does not convert AC current to DC, but leaves the current as an AC/AC ratio.
What type of power supply for my motorhome?
ABL Transfo can help you choose the right AC/DC power supply. You can find a 230VAC – 12VDC AC/DC power supply in our shop by clicking on the button below:
What wattage should I choose for my caravan power supply?
Calculating the power of your motorhome and caravan power supply is very simple!
Simply add up the power of all your appliances to be powered and multiply by x1.25 (safety margin). To do this, let’s use an example:
- Heating: 100W
- Refrigerator: 200W
- Water pump: 25W
- Television: 50W
So let’s add up: 100 + 200 + 25 + 50 = 375 x 1.25 = 468.75W
So in this particular case you can opt for a power supply that is closer to 500W or any other higher value, but never lower.
Note: 1W = (approximately) 1vA.
How do you power 24V appliances in your caravan?

Si vous avez besoin d’alimenter de l’équipement en 24V dans votre camping car, vérifiez bien que l’on parle de courant continu 24VDC et non pas de courant alternatif 24VAC.
