What Is A Power Supply
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.
Since it involves with the handling of current some preliminary precautions must be kept in mind. Few things that will be required to carry out this are wire stripper, tools for crimping and ring terminals. The following instructions are carefully carried out for safety. This involves only a few connections and some initial steps.
Alternating current is used for supplying power to appliances. AC current flows continuously from positive to negative direction and then back to positive direction. There is no fluctuation or change in direction in DC current. Some devices can run with the help of battery that is they use Direct current or DC power. The AC to DC converter has DC power terminals . From these DC power terminals remove the wiring nuts and thumb screws . This can be done by turning the converter to left direction.
The insulation is stripped for about half an inch from both the positive negative wires from the device that has to be converted to AC supply. This DC device can then be converted to the converter. The standardized colours of these wires are red for positive and black for negative wires. It is always safe to check the manual of the device to make sure of the colour of the two wires.
After the insulation of the wires is removed, ring terminals are slid to the end for each of the two wires. Then the terminals are crimped to the wire with the help of a tool that is used for crimping.
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.
There are two separate portals for the connection of positive and negative wires from the ends of the DC device. The positive end of the wire is fastened to the positive terminal of the AC to DC converter where as the negative end of the wire is connected to the negative terminal of the AC to DC converter. Using thumb screws and the wing nuts the terminals are connected to the wires in a proper way.
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.
