What is 12V 300ma?
This is a new mini led driving ic adapter. When the led is on, the adapter will light up. What’s more, this is a high quality converter module with excellent performance as the adapter is small. The adapter comes with overcurrent, overvoltage and under voltage protection.
Can I use 12vdc for 12vac?
If its a lower voltage regulator (say, unlikely 9V or 5V) it might work fine. With AC, current flows through 4 diodes, feeding DC only uses 2. So they have to handle double the current (which may or may not be fine).
Can you interchange AC adapters?
– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.
Can I use a 12V 1A power adapter on 12V 1.5 a device?
No, a 1A power supply isn’t a replacement for a 1.5A power supply. It might work if the disk actually takes less than 1A and the power supply was sized with some margin.
What does 12V 400ma mean?
It means 400 milli-amps.
What does output 12V 1A mean?
12V 1A, means it can provide the current of 0A to 1A. while maintaining it’s 12V. After 1A, the voltage is not guarantee. For the current rating on the product, it indicate the maximum current the product will draws from it’s power supply.
Is 12vac the same as 12V?
AC power to go through the rectifier/switching power supply into DC power can be used for electronic products. simple measurement method: with a stylus pen (non-ordinary pen) on the wire foreskin, 12V AC will still show, 12V DC no display. Safety. 12V DC is safer than 12V AC.
Can I use 12V 1A for a 12V 1.5 a router?
Yes. Using something too weak would be a problem. DC devices are almost always voltage-regulated, so they can handle somewhat more than spec voltage (6V in on a 5V device is generally fine, and is how many 5V devices run on 4x 1.5V batteries), and they’ll only draw as much current as they need.
Can I use a 1.5 amp charger for a 1 Amp device?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
