Can a 12V 5-6A device be run with an AC-DC converter rated at 12V 12A?
As long as the converter (or any power source) is rated at the same voltage, with more current than the device needs.
Sometimes, a device may have a higher initial current surge than it's operating current, keep this in mind. Some converters do a good job handling momentary surge, some don't.

Converting 5 Volt DC to 12 Volt DC . Best thing to use, (well, at least the quickest) is a DC to DC converter module.
Depends what current out you want. Step-down transformer and a bridge rectifier and smoothing curcuit, or switch mode supply. Spend less than a tenner and buy a battery charge…r
Use Inverter. Use Inverter
"How do you convert 12v DC to 5v DC?" . Simple use a 2.25 ohm 25watt ballast resistor;renault used them to drop the voltage for the Engine control computers.
if you have 12v dc then you can use a 4 ohm resistor
First you need a step down transformer. A step down transformer has less turns of copper in secondary then in primary.You can calculate with this formula # of primary turns/V…oltage of Primary= # of secondary turns/Voltage of secondary When you know 3 factors, you can easily find out the forth one by easy mathematical calculation From a step down transformer the 12 V AC output, needs to be converted into 12 V DC by a simple reverse bias or diode A diode does a HALF-WAY RECTIFICATION which means it allows one way of current, cut downs the reverse that is AC Current in which change of polarity takes place or a diode rectifies AC to DC or unidirectional current
You'll probably have to have a step-down transformer to take the 220vac down to 110vac. Then you'll have to have an Ac to Dc converter box to change the Ac to Dc volts. The …converter will probably have an adjustable output so that you can dial in 12vdc.
By power pack, I'm assuming that you mean transformer or power adapter? It's not recommended. One of three things may occur - 1) The powered device will fail due to undercur…rent from the transformer. 2) The transformer will fail due to the connected device attempting to draw too much current. 3) The transformer will overheat, melting its housing and possibly starting a fire from nearby combustible materials (including the housing and wire insulation). I would tell you that you should go to your nearest Wal-Mart, Target, Radio Shack, or another retailer that sells power adapters, and purchase one with enough power for your application. (Hint - you can always go a little over on current and be safe, though the transformer won't be as efficient.)
24V to 12V 400W DC Inverter . 24V to 12V 400W DC Inverter . 24V to 12V 20A 400W DC to DC Inverter. Does little to change my PV system 12v 24v me the problem arose of what… to do with investors who already had 12V. I was looking for a pattern online and found several schemes with linear regulators 20A, this solution although quite simple, due to the huge losses they have is not advisable. Ideally, a converter switched, high-performance. At the end I found nothing I liked and decided to design my own. Circuit characteristics: Output current: 20A at 12V (15A continuous and 30A Momentary), Input voltage: 18 to 30V DC, Output voltage: 5 to 20V, Operating Frequency: 70kHz, Effectiveness: 95%, 400W maximum power, Protections: Above current (30A) in the F1 circuit, D1 and F1 polarity in the circuit. . The circuit is designed to have the best performance with current components and quality, but at the same time as simple as possible and to be used in different applications such as solar or reducing voltages on 24V vehicles. The circuit begins with DC 24V power connector CN1, CN2 and the diode D1, the D1 is a protection against neglect by reversing the polarity. What is a regulator of type 7812, this circuit provides a fixed voltage of +12 V to power the IR2111 driver and the PWM module and temperature control. The PWM module is responsible for providing the square wave pulse width modulated (PWM) on outputs S1, S2, this signal is proportional to the present intention in VSF points output circuit (output voltage source) and the entry module, these points are the positive feedback loop of the module, setting out the intention is achieved by varying the value of the trimmer P1 in the PWM module. The temperature control module is responsible for maintaining the temperature of power MOS-FET and the circuit to an acceptable operating temperature, this control also reduces consumption and noise of the fan stopped keeping track when not necessary to its operation. The amplifier is built around a driver for MOS-FET IR2111, this component contains within it everything necessary to drive and control in so -BRIDGE HALF the power MOS-FET. PWM signal enters the module pin (2) of IC1 by two diodes that mix the two output signals S1, S2 and the balancing resistor R3, the resulting signal is a square wave with a fixed frequency of 70kHz modulated width from 0% to a maximum of 98% depending on the intention +12 V.esta output square wave signal is amplified by the power stage T1, T2, T3, is filtered by the inductor L2, built with a core ferrite toroidal high value type, this type is used very often in the power supplies switched to filter the type of outings and intentions as far as possible eliminate the AF component (high frequency) of the ongoing intention of leaving the source. After the intention L2 is rectified by a group of diodes D10, D11 high-performance type Schottky , diode cough is characterized by low internal resistance and high operating frequency to be suitable for applications in switching power supplies. To finish is filtered and stabilized by two capacitors electrolytic C10 , C11. The end result is a power supply voltage quality and very stable.

use 230v to 12 v transformer after use rectifier circuit.
No, the supplies output is too small. To run a 550mA device a supply source of 600mA and larger would be needed.
Yes, if the device has a built in step down transformer. Think of it this way, the electricity in your household is a typical 230v. Mobile phones tend to use 6v of electricity…. So when you plug your phone charger into the wall socket, 230v will run directly into that charger, through the cable and into your phone, typically blowing up the device or overloading it. That's why the charger has a transformer in it (a step-down transformer) which steps down the voltage from 230v to about 6-12v. So hopefully that explains your question. If not, try to eleaborate a bit more so i can possible help further. Thank you.
DC 12V power supply can convert 110/220V AC power source to 12V DC.
You cannot convert 12VDC to -12VDC. However you can get these two voltages simultaneously by using a centre-tap transformer secondary. One half of the centre-tap, depending on… the transformer ratio, will give you a +12VDC and the other, -12VDC, all relative to the centre point. Answer +12 V and -12 V are potentials measured with respect to some reference point. In the case of a vehicle, for example, the negative terminal of the 12-V battery is connected to the metal parts or chassis (a situation called a 'chassis earth' or 'chassis ground') of the vehicle. All potentials measured with respect to the chassis will then be +12 V. If, on the other hand, the positive terminal was connected to the chassis, then all potentials measured with respect to the chassis would be -12 V. The only time we assign 'plus' or 'minus' to potential differences ( voltages ) is to indicate their sense or their direction . If voltage A is taken as the reference voltage, we allocate a positive direction to it; if voltage B acts in the same direction then it, too, is allocated positive; if voltage B acts in the opposite direction, then it is allocated as being negative.
Yes, no problem whatsoever. The adaptor will only be operating at 50% of it capacity.
Yes - you just need a transformer that will step down the voltage by a factor of 19:1
