The role and function of the domestic inverter UPS

The role and function of the domestic inverter UPS, contains a storage device, and the inverter as main components uninterruptible power supply constant pressure constant volume. UPS in its early stage of development,Home inverter ups Rack mount ups the domestic inverter UPS it with the birth of computer and the emergence of domestic inverter, UPS is one of the common peripheral equipment of computer. The inverter UPS is only regarded as a standby power supply.Home inverter ups  Later, Rack mount ups because the voltage surge,Rack mount ups UPS charger inverter, voltage spike, transient voltage,Rack mount ups voltage sag, sustained overvoltage or undervoltage and voltage interruption of power quality problems, domestic inverter UPS make the electronic system of computer equipment such as the interference caused by damaged element, Rack mount upssensitive,Home inverter ups  Rack mount upslow frequency UPS, information loss,Rack mount ups disk program has been obliterated etc.Home inverter ups Rack mount ups seriousconsequences, UPS inverter charger lead to great economic loss. Domestic inverter UPS it with the birth of computer and the emergence of domestic inverter, Home inverter ups UPS is one of the common peripheral equipment of computer.Rack mount ups Therefore, UPS inverter charger has been paid more and more attention, low UPS and gradually developed into a power protection system with voltage,Home inverter ups  frequency, filtering, anti electromagnetic and radio frequency interference,Rack mount ups the domestic inverter UPS against voltage surges and other functions.Rack mount ups Currently on the market can buy different kinds of UPS power supply, Home inverter ups the output power from 500VA to 3000kVA range.Rack mount ups When there is a power supply UPS, Home inverter ups UPS regulator for electric power supply for computer. Domestic inverter UPS at this time was an AC power regulator, and it is also the built-in battery charging.

Domestic inverter UPS role?

  Domestic inverter UPS: power input in normal, input power through mutual throwing device to the important load power supply, at the same time the system controller automatically power detection and the charger to charge the battery management. Usually EPS charger capacity equivalent to only10% of battery capacity (Ah), only need to provide the battery float chargingor power supply function, does not need to have the ability to provide DC power supply directly to the inverter. At this time, the city electricity throughmutual investment in EPS for users to emergency power supply. At the same time, in the control system of the EPS controller, inverter stopped working in the automatic shutdown state. In the actual use of the user load is a power source, usually called the EPS emergency power supply in a sleep state, can effectively achieve the effect of saving energy. When the input power supply interruption or electric voltage limit (± 15% and ± 20% rated input voltage),command control system automatic switching device (0.1~4) in S short time switching to the inverter power supply, EPS system is provided in the battery DC power support, to supply the user load.  domestic inverter UPS  when the input voltage to resume normal work, the system controller EPS to send command to run off the inverter, also through mutual investment switch from inverter to AC bypass power supply switching operation. Then EPS and  pure sine wave UPS  in providing power to the load via AC bypass power supply path, while continuing to charge the battery through the rectifier charger.
