What is a controlled power supply?
The controlled power supply is a device used in conjunction with electrically powered appliances. It ensures that the device is protected from common fluctuations in electricity flow that could cause damage or poor performance. The most common type of controlled power is used on computers that have fine circuits and specific current requirements. Other types of appliances also use simple or complex forms of energy controller. For example, power plants generally increase the voltage of electricity that goes into the municipal network. This is because it is more effective to send electricity over long distances when it is to a higher voltage. For this purpose, the Power Companies employ alternating current or direct current or direct current (AC or DC). Local transformers reduce the voltage to safe levels of household use.
The household current should be maintained at a standard voltage. In practice, however, different factors can create fluctuations or momentary increase in current, callanem spikes or energy overvoltage. Simple appliances will not be damaged by these fluctuations, but sensitive computer circuits may be permanently damaged. Many appliances include computer circuits, including phones, TVs and even coffee machines. For this reason, some of these devices may use regulated power supply; It often appears as a small closed box on the plug or the power cable of the device.
One type of controlled power is called a power supply with a switched mode or SMPS. SMPS uses various fuses, filters and other devices to control simultaneous travel to the device. These devices quickly switch the current and turn off and create a standard voltage level, with regard to less incoming fluctuations or increases. The fuses in the power supply of the switched mode can also protect the device in the event of a sudden energy increase.
Another form of controlled power supply is the overvoltage protectorAlso known as suppression of overvoltage. This device has many forms, but the most common is the output belt. The overvoltage protector also protects the appliances from sudden electricity overvolts, such as devices caused by lightning strike on electric lines or equipment. In the case of overvoltage, the protectionist's power supply will shorten or otherwise dispersed excess electricity, prevents it from reaching the device and protects the fine circuits of the computer from damage.
