The DC or Direct Current power supply is one of the 2 forms of electricity, the other being the AC power supply or Alternating Current. The difference between the two is the DC power supply has the electricity flow moving in a single forward direction while the AC electricity flow moves both forward and backward. The DC current is more commonly used because it is much easier for smaller electronic device to utilize and can run on battery power too. A lot of appliances and electrical gadgets found at home such as computers, stereos, and the like usually have a built-in DC converting rectifier. Since most of the electrical power coming from outlets come in the form of AC, it must be changed to DC with the use of the rectifier. The rectifier is a device that is able to convert AC to DC, allowing the current to flow towards one direction only. DC systems have several types of switches or sockets because of the low voltage it uses up. With the Direct Current power supply, you are able to make use of electricity to power up almost every electrical appliance and other devices at home. Using a DC power supply does not need a great deal of technical know-how. It is actually a very simple process that follows a few easy steps. Here’s how to do it.
- Plug in the DC power supply. The first step to take is to plug in the DC power supply’s outlet end into the surge protector outlet, which does the job of protecting any of your electronic devices from power surges. These power surges are sudden increases in the power voltage that could damage your appliances.
- Attach the DC power supply into the electrical device. After you have plugged on the DC power supply to the outlet, connect the other end to the specific electrical device you will be providing power with.
- Check if power is flowing properly into the device. Make sure that each of the DC power supply ends are connected properly and securely into their respective outlets. You will know if you have done it right by turning on the power of your device. Also make sure that none of your DC power supply cords are on the way. Aside from tripping on them accidentally and hurting yourself, you could also pull out the cords from their connections or damage your appliances or other devices.
When selecting any type of DC power supply, specifications are a very
important thing to consider. There are several DC power supply
specifications, each one featuring a specific component of the power
supply’s performance. These specifications differ according to
applications, and are necessary for obtaining the appropriate power
supply for specific needs. The specifications include the power supply
and voltage, which are the most essential parameters; line regulation,
the disparity on the output voltage whenever there is a change on the
input or the line voltage; load regulation, which is the difference in
voltage output when there are changes in the load; ripple and noise,
which are joined as a single measurement; power supply stability, which
is constancy of the output voltage; and temperature stability, which is
measured as a percentage for each C degree.
