# Can I use 24VAC for 12VDC?

## Can I use 24VAC for 12VDC?

If you’ve ever been on a job installing a 12VDC device with only a 24VAC power source, you need to buy a couple of these to keep on your truck. This compact device converts voltages from 20-28VAC to 12VDC(1.5A). Great for CCTV Cameras, Access Control, Fire Systems, and security applications.

### Is 24VAC the same as 12VDC?

24VAC can run longer distances than 12VDC. It isn’t because of the alternating current, but because of the 24V. To supply 24 Watts will require 1 amp at 24VAC and 2 amps at 12V. The voltage drop in a wire is proportional the amps only.

How far can you run 24Vac?

24V AC Power Max Wire Distance Chart

24 AWG 20 AWG
10 VA (417mA) 103 feet 286 feet
20 VA (833mA) 52 feet 142 feet
30 VA (1,250mA) 34 feet 95 feet
40 VA (1,667mA) 26 feet 71 feet

What does 24Vac stand for?

The 40VA means “volt-amps” and is a measure of power handling. It means that you can draw 40VA / 24V = 1.67A from the secondary.

### How far can you run 24vac?

Can a transformer convert AC to DC?

A transformer cannot convert AC to DC or DC to AC. The transformer has the ability to step up or decrease current. A step-up transformer is a transformer that raises the voltage from the primary to the secondary. The voltage is reduced from primary to secondary by the step-down transformer.

### Does 24VAC hurt?

If you have a power limited 24vac your pretty safe , but if you have 24v with high amperage potential its dangerous because it can cause a fire.
