Question:

How do you choose the right UPS?

Now you need to buy a UPS uninterruptible power supply for emergency after power failure. 2 R910 with 4 1100W power supply (per Taichung 2 of which there are two sets of redundant power supply), T7500 workstation, respectively is Dell and T710, and a MD1200 storage, so there may be a 10kW UPS request can drive all of these machines at the same time, mainly for power for some time to shut down, after the power can be maintained for more than 15 minutes. How do you choose UPS and batteries to meet the demand?

Answer:

These functions are provided for the UPS of data centers to meet the requirements of the IT power supply specified in industry standards and technical specifications. However, they provide different protection levels and different ways of providing protection. The UPS sold on the market generally has three topologies for protecting IT devices:? backup UPS allows the device to work with the mains power until the UPS detects the problem before switching to the battery power to protect the device from voltage sags, surges, or power outages.? online interactive UPS before entering current protected devices, increase or decrease the mains voltage as required, or use battery power.? dual conversion UPS separates the equipment from the mains mains - switching the power from AC to DC and then switching to AC to provide the cleanest power and the highest level of protection.
At its most basic level, UPS performs two basic and complementary functions:? adjust the input power to eliminate the most common voltage sags and spikes on the public power grid and other major power supplies? by dynamically selecting power from public grids, batteries, backup generators, and other available power supplies, a transition power is provided for voltage sags and short power outages (5 to 1 hours)
Which design fits your data center? The way manufacturers design products for these topologies has a major impact on overall power performance, availability of data centers, and total cost of ownership. This paper provides an objective view of some important issues that should be considered in selecting the best UPS internal design according to the requirements.
Other topologies such as ferromagnetic resonance and rotary designs are also designed for specific applications (such as industry or harsh environments). This article tells about the typical static UPS topology used in most IT environments.
Some of the latest UPS models have multi-mode capabilities, often referred to as' economic models' or 'efficient' models". The UPS generally operates in an efficient mode unless the power condition causes it to switch to a higher protection level dual conversion mode.
