Can I use a 12v1 5A adapter with 12V 3A device?
A 12V DC device needs a 12V DC adapter. Amperage is the amount of power your device uses. The adapter you order has to be able to supply AT LEAST the amount of Amps your device draws. If your device states it is 12V 3A, a 3A adapter can handle that load, but so can a 4A and 5A.
Can I use 12v1.5 a for 12v1. 25 a?
Same voltage more amp capability is fine, same volts lower amp capacity is bad. Power supplies and adapters are rated at what they can supply, your equipment is rated by what it will draw. Yes.
Can I use 1.5 A for 2A?
Current is load, not the output. The output is the voltage. The thing you need to be careful about is the output voltage rating, which you mentioned is the same for both the adapters. So, you will be fine using the 2A charger in place of the 1.5A one.
What does 12V output mean?
12V power supplies (or 12VDC power supplies) are one of the most common power supplies in use today. In general, a 12VDC output is obtained from a 120VAC or 240VAC input using a combination of transformers, diodes and transistors.
Can I use 500ma instead of 300ma?
No, it’s ok.
What is the output of a 12V 1A adapter?
Output: 12V 1A means this equipment can handle ( consume or generate) 12Watts of power Output: 12V 2A means this equipment can handle ( consume or generate) 24Watts of power Why is it not rated directly in Power?
Can you hook up a 3 amp power adapter to a 12V load device?
Since 1.5 is less than 3 and 12 = 12 then you should be OK. Adapter because your load device has a resistance rating that draws 1.5 amps. That means in theory that 3 – 1.5 = 1.5 which means that 2 devices actually rated at 1.5 amps from a 3 amp power adapter can be hooked up.
What do I need to make a 12 volt power supply?
Things that you will need to make this power supply is… Transformer that has an output of 14v – 35v AC with an output current between 100mA to 1A, depending how much power you will need. (I found a 16v 200mA transformer in a broken alarm clock.)
Can a 1.5A power adapter be used at low current?
At low current, say 0.5A or so (where many 1.5A rated devices are likely to operate) the output voltage may in fact be several volts higher. The device being powered may be able to tolerate higher input voltages without harm, at least for a while, but higher input voltage likely results in higher heat dissipation.
