What's a UPS?
UPS (Uninterruptible Power Supply) - this uninterruptible power supply unit, also commonly referred to as the uninterruptible power supply unit, provides an uninterruptible power supply in the event of a main power supply failure or voltage drop to an unacceptable level. The UPS allows you to safely maintain your equipment in an efficient state, depending on the size of your equipment and the amount of energy required by it.
UPSs are more expensive than battery power. The device is usually recommended for more important devices such as servers, the UPS allows a consistent, filtered power supply for important devices that need to continue operating and processing data.
The UPS protects your device from overvoltages, network voltage drops, breakdowns and other power problems. They filter the voltage in the device to reduce or eliminate equipment damage during power problems.
Standby is the most basic UPS topology, the stand-by power supply is powered by back-up batteries in case of power problems such as voltage loss, short circuit or power surge. When passing mains power drops below or exceeds the safe voltage level, the UPS switches to DC battery power and then turns it over to AC power to start the connected devices. This system is designed for consumer electronics, entry-level computers, POS systems, security systems and other basic electronic devices.
The Line-interactive UPS uses technology that allows you to correct minor power fluctuations (under and over voltages) without switching to battery power. This type of UPS has an autotransformer that adjusts low and overvoltage without switching to battery power. Interactive rope UPS models are typically used in consumer electronics, PCs, home theater electronics, network equipment and servers.
Double conversion (online) UPS provides constant, clean and almost ideal power regardless of the input power status. This UPS converts the incoming AC power to DC and then back to AC. UPS systems with this technology run on isolated DC power for 100 percent of the time and have zero transfer time because they never have to switch to DC power. Dual-conversion UPS systems are designed to protect critical IT equipment - installations in data centers, high-end servers, large telecommunications installations and advanced networking equipment.
