Uninterruptible Power Supply Green

Aug 25, 2017

As the development of information technology, the network has become an indispensable part of people's lives and work, constitute the network of digital room power supply reliability has become the key, and the reliable supply of the engine room is the most important, usually uninterrupted Power supplies are used to maintain uninterrupted operation of critical commercial equipment or precision instruments such as computers (especially servers) or switches, UPS Uninterruptible Power Supply to prevent loss of computer data, disruption of telephone communication networks, or loss of control of the instrument. The following is an introduction to uninterruptible power supplies Related Content.

Uninterruptible power supply is in the power grid abnormalities (such as power outages, undervoltage, interference or surge "also known as: surge current") in the case of uninterrupted electrical load equipment to provide backup AC power to maintain the normal operation of electrical equipment.

Uninterruptible power supply features

1, green, energy saving, environmental protection: the world energy pattern changes intensified, the international oil prices shocks, the global energy supply situation, UPS Uninterruptible Power Supply energy saving and environmental protection has become the UPS manufacturers to carry out product technology innovation guidelines. For UPS, the input power factor indicates the ability to absorb the active power of the grid and the extent of its impact on the grid. UPS Uninterruptible Power Supply Reducing the input harmonics of the power supply not only improves the load characteristics of the UPS to the power grid, reduces the serious pollution caused by the power grid, but also reduces the harmonic interference to other network equipment. Many UPS manufacturers have introduced a product power factor close to 1, UPS Uninterruptible Power Supply can minimize the consumption of reactive power.

2, high frequency: compared to the traditional power frequency UPS, high-frequency UPS power factor correction and high-frequency soft-switching technology, eliminating the need for power frequency conversion links, so the operation more efficient, harmonic pollution on the grid and Reactive power consumption is very small, fully able to meet the relevant domestic and international power industry standards. In addition, UPS Uninterruptible Power Supply the high-frequency power conversion apparatus has a significant effect in reducing the volume and weight of the magnetic member, reducing the manufacturing cost, curbing the running noise, saving the environment and the like, and is increasingly recognized by the user.

3, high-power, modular: As the rapid development of IT industry, the data center data volume is also the rate of explosion continued to grow, followed by increased power consumption. UPS on the one hand toward the direction of higher power development, on the other hand to cope with uninterrupted power capacity expansion of the demand, product modularity is an irresistible trend. More personalized user needs,UPS Uninterruptible Power Supply a larger data center scale and higher maintenance costs make UPS is no longer a simple uninterrupted power supply equipment, for a variety of industries in a full range of power supply and management solutions will be much favored by the market The

Uninterruptible power supply works

When the mains power 380Vac normal, the DC main circuit has a DC voltage, DC-AC AC inverter supply, the output stable 220V or 380Vac AC voltage, UPS Uninterruptible Power Supply while the mains after the rectification of the battery charge, when any time under electricity or Suddenly power-down, by the battery through the isolation diode switch to the DC circuit to send power from the power supply to the battery without switching time. When the battery energy is about to run out, uninterruptible power supply sound and light alarm, and the battery discharge point to stop the inverter work, long alarm.

The uninterruptible power supply also has an overload protection function that, UPS Uninterruptible Power Supply when overloaded (150% load), jumps to the bypass state and automatically returns when the load is normal. When a severe overload (over 200% of the rated load) occurs, the uninterruptible power supply immediately stops the inverter output and jumps to the bypass state, and the front input air switch may trip. Eliminate the fault, just close the switch, restart the machine began to resume work.
