Traditional online UPS power supply has many problems, mainly in:

  Operating inefficiencies, and generally light load efficiency is lower than 80%.
  Adopt to the low frequency transformers ,and it will consume a large amount of steel and copper, high cost and bulky size.
  Adopt to the not controlled or phase-controlled rectifier, which decreases with decreasing load input power factor and produce a lot of power system harmonic current injection.
  Availability poor, single can not be redundant, low reliability, high failure rates, difficulty in maintenance and initial investment costs.

At present, these problems, experts agree that UPS power supply should provide "green, modular, intelligent" direction. So there will be a green modular online UPS power supply production. We see the green modular online UPS power supply several advantages:

1) high reliability: the traditional online UPS power supply adopt to single-or hot backup or 1+1 parallel, some security risks for users, but modular online UPS power supply using n + x parallel, price, safety and reliability is to get a much bigger leap.

2) high efficiency and energy saving: traditional online UPS power supply input power factor is less than 90%, multiple type modular online UPS power supply input power factor close to 1 (0.99), enter the total harmonic distortion (THD) is just 5%.

3) adopt to the multiple type power supply: the total number of input or output with 4 standard 6 (with three/single/single, single, triple/triple, single/triple; 50/60Hz, and 110/220/230/240VAC) the flexibility to meet the different situations.

4) powerful scalability : it adopts module superposition type design, UPS power supply capacity can be increased or reduced, realization of investors ' "on demand" needs to meet the UPS power supply along with the user's business development in order to achieve "dynamic growth".

5) Green: the CCM current continuous mode of operation, greatly reduce the power interference, similar to the input power factor 1 (0.99), enter the total harmonic distortion (THD) is only 5%, well below the traditional UPS current harmonics is generally 30%.

6) online hot plug: sections module for online hot-plug operations, provided a guarantee for product upgrade or maintenance.

7) Intelligent interactive: interactive monitoring technology is used to help users deal with flexible and efficient system crisis, through real-time communications or network monitoring.
