Using a 24vdc supply


#1

Hi.

Im based in South africa. We have readily availible 24vdc supplies. Can i supply the unit with 24vdc vs 24vac?

The input is 220vac.

Thanks

Alas, no.

Rachio hardware is only able to turn off the zones upon the zero crossing, meaning that with a DC supply, your zones will never turn off…

You could look into a 220 to 110 V converter, but frankly majority of them are not designed for continuous use so I would recommend that you take the time to find a suitable supply.

The key would be to search for the right keywords: “24vac 24va” is what I recommend you try. Here is an example (link) from a UK amazon listing, be careful not to go too high over 1 amp / 1000 mAmp transformer rating, often times the voltage rating is specified at close to the maximum ouput and voltage may drift much higher than 24 VAC at low / idle output levels.

Good luck,
Gene

P.S. Be on the lookout for funky math listings, such as another UK listing here (link), description rightfully shows 48VA (24VAC * 2 Amps = 48 VA), but the title incorrectly lists it as 24VA product.

P.P.S. Let us know which ever supply you will end up using

Thanks. I landed up buying a 220vac to 24vac supply here…
