An effective option to avoid problems with electric current is the use of devices such as Ups (uninterrupted power supply), which provide power to all connected devices, ideal for devices whose operation is affected by delays in the switching of power supplies. Ups also serve to improve the quality of the electrical energy that reaches the loads, filtering voltage surges and dips and eliminating harmonics from the network in the case of using alternating current.
There are many different models ideal for different equipment, to work in different situations, and more. There are the normal ups, which have a much longer useful life, and inverters, ideal for electrical equipment such as appliances, which are not affected in their operation by long periods of delay and power outages.
Many premises, institutions and even homes require Power Backup Systems to protect their equipment, and to be able to provide power in the absence of power or failures in the electrical system.
