Technology definitions Chinese name: English name of uninterruptible power supplies: uninterrupted power supply, UPS Definition: when the normal AC power is interrupted, the DC output of the battery into alternating continuous supply of power equipment. Applied science: Electric power (a subject); electricity planning, design and construction (two subjects)
UPS (Uninterruptible Power System), i.e., uninterruptible power supply, comprising an energy storage device, the constant voltage to the inverter as the main component of the constant frequency of an uninterruptible power supply. Mainly used for a single computer, computer network systems, or other electronic devices to provide uninterrupted power supply of electricity. When the mains input is normal, UPS will be supplied to the load after the electricity regulator, in which case the UPS is an AC mains voltage regulator, while also charging the battery into the machine; when the electricity interruption (outage) When, UPS immediately internal battery power, the continued supply of 220V AC power to the load through an inverter to convert the ways in which to maintain the normal work load and protect the load the software and hardware from damage. UPS is an abbreviation for Uninterruptible Power Supply, when the power failure, KINGPOWER A series UPS UPS can continue to supply power to the computer.
The connection between the computer and the power supply to ensure uninterrupted current equipment. UPS devices use batteries to keep the computer still running for some time after a power outage. UPS devices are often too large and the voltage of the voltage is too low both provide protection. (UPS)
Uninterruptible power supply (UPS), during a power outage, a computer or other device continues to provide power.
UPS may be one of the following:
Battery system.
Rotary UPS, which uses a large inertia of the flywheel to provide short-term power supply for your computer.
AC generator running internal combustion motors.
UPS equipment There are two types:
Online and sunk. Set beside the device starts only when the power is dead. Therefore, it must have a bootable backup power supply circuit to do it within 5 microseconds. Fixed-line equipment for the computer to provide power. Because of this feature, it does not open when no electricity. If the outside of the power supply is broken, the battery inside the unit continues to provide power to the computer. Although the online UPS is the best choice, but better than much more expensive UPS sunk. However, because the online component of the computer to provide a constant power, so this power is always stable.
When purchasing a battery backup system, you need to understand some of the following equipment:
The UPS batteries can provide time electricity.
When the UPS is in power after a slow operation, UPS to the server whether Germany Piller UPS uninterruptible power warning systems. Have the UPS to eliminate alien voice transient power regulation.
Battery life and how to downgrade it over time.
Battery no longer provide backup power when the device can warn you.
Whether these batteries can be replaced.
Preparing to install equipment needed to know the power demand of UPS. For servers, you may install CPU (and other additional equipment), monitors, external routers, hubs, and wiring center. You can find their power needs by viewing these rear plate of the device. Performance is measured by the main UPS VA (VA), which refers to the line voltage multiplied by the current (amps). The need to add together all the equipment connected to the UPS power requirements, then buy a UPS can handle the load. Richard amperage the device after the first board, and multiplied by the voltage value (typically 120 volts in the United States), and then each device the numbers together, and select a suitable UPS. UPS is connected to the file server usually requires one additional cable, when UPS slow electrical work in the post, through which cables warning file server. Then, the server process must be carried out within a certain period of time to download. The supervisor at one end of the cable requires a stereo plug (to insert next to the UPS oversight board or a non-SS key card PS / 2 file server) or a 4-pin mouse connector (to be inserted into a PS / 2 file server mouse port). Specific UPS supervisor and the other end of the cable is required to have selected the desired type of connector. Some manufacturers have developed a number of advanced features for their power protection equipment. American Power Conversion's Smart-UPS series, by means of a control program called PowerChute software, network management personnel to provide diagnostic information. This software is installed on the server, and communicates with the UPS via a single cable. Then, managers can track power quality, UPS operating temperature, line frequency, UPS output voltage, maximum and minimum line power, battery strength, line voltage and UPS load.
