What Is A Power Supply

Posted on January 25th, 2010 by Admin

Most of the power supplied by batteries is direct current supply. Even in the car, the power is supplied in direct current. Hence the music and stereo players are constructed in such a way that they work in direct current. Some of these systems may be portable and can be used at home. In such cases they need to be played in alternating current since AC is used domestically. It is not possible to play a music player from a car in alternating current supply. Therefore a converter is used. There are numerous types of this converter. One such converter that we use to do this is a converter with thumb screw connections. It involves simply changing the connections between the converter and the electronic devise. How to wire an AC to DC converter is shown in this article.

But these convertors can be used only when you are in need of power in DC like components of a car audio system and other parts of it. A standard household power is required for it to access the DC output power. Wiring of this AC to DC converter consists of several steps which are simple in carrying out. Few initial preparatory steps and simple wiring connection can give a good AC to DC converter. A proper wiring can ensure the perfect functioning of this converter. The reason for doing this is to get a stable DC output.

The first thing to be done is to remove thumb screws or any similar thing like wing nuts. These are removed from the terminals of the DC power of the converter. This can be done by turning it to the left.

The device that needs to connected to AC to DC converter is taken out . The device has both positive and negative wires . We need to strip off the insulation . The insulation is usually around half inch. In most of the cases the positive wire will be colored red and the negative wire will be colored black . However it is necessary to ensure this. So read the manual carefully and study the working diagrams of the device to check this.

Now its time for us to use the ring terminal and wire strippers. The terminal is crimped with the wire using the crimping tool. On the other end of the wire which is free attach the ring terminal.

The terminals with the positive negative ends are put on their respective posts of the AC to DC converter. The connections are then tightened by the wing nuts or thumb screws that are available in the converter. These screws help by keeping the wires in position.

The last step is the AC plug has to be plugged to the outlet of the wall. The DC device needs power which is provided by the AC to DC converter . So switch on the converter after making all the wiring and connections properly. Do not make an attempt to switch on the AC to DC converter till all wiring and connections are completed or else it may cause damage to the equipment. Put the protective cover on to the appliance.

The above instructions on How to wire an AC to DC converter are easy and need prior supervision. It is also necessary to make sure that all the connections are made properly before the converter is turned on. The wiring is simple and can be done if some basic concepts of connections are known.
