Australian regulatory power adapter Frequently Asked Questions:

1. What is the DC power supply?

Make constant current circuit forming device, such as batteries, batteries, generators, DC, called the DC power supply.

There are both positive and negative DC power supply electrodes, the high positive potential, the potential of the negative electrode is low; when two electrodes in communication with the circuit, the DC power supply to maintain a constant potential difference between two electrodes, whereby the outer circuit formed of the positive electrode to the negative electrode constant current.

2. What is the DC power system?

DC power is applied to the hydraulic system, power plants, substations and other users to use various types of DC power supply for the signal equipment, protection, automatic equipment, emergency lighting, emergency power and breaker points, closing operation provides DC power power supply equipment. DC power system is an independent power supply, it is not a generator, auxiliary power and influence the way the system is running, and in the case of an external AC power interruption, guaranteed by the backup power supply - the battery continues to provide DC power supply of critical equipment.

3. How to design an adjustable DC power supply?

Power MOSFET, a unipolar voltage-controlled device, which not only has a self-shutdown capability, and has a drive power of small, off-speed, etc., is commonly used switching adjustable DC power switching devices. Control using MOSFET switching power supply with small size, light weight, high efficiency and low cost advantages,

4. acid electrode DC power supply can be used to burn it?

Magnetic blow DC power supply is relatively large, can lower current and changing the perspective to improve the welding electrode; for basic electrodes, the magnetic blow the impact is great; only a good arc stability before they can use the AC , arc stability and good acid electrode, usually with AC power, the basic needs of drug skin fluorite content only available DC; so, for acid electrode, the guarantee and the small current grounding, can be used; however recommended to use the AC would be better.
