Today, data centers house massive amounts of equipment that handles very important data. These sites require a power system that can operate around the clock without fluctuation. According to the high demand of the equipment, 2N power solutions and △2N power solutions are more suitable for users like those operating data centers for AC UPS to supply power for IT equipment. The △2N power solution which not only ensures dual bus power supply for loads, but also improves rated load rate of each UPS and decreases overall number of UPS, leading to great reduction of investment in the earlier stage and later operation cost.

Model of △2N power solution

Features

In AC UPS △2N power solutions, the 3 vertexes of the triangle represent the 3 independent power systems. Load a, load b and load c in the figure can be respectively regarded as one computer room, a column of IT equipment or one device. Each side of the triangle can be regarded as an independent 2N power solution.
a) Each IT device is powered by dual power sources. Under normal conditions, two way supply electricity equally and then the load rate of each UPS is 66%.
b) If a power failure occurs on one UPS system, its load will be powered by other 2 related power systems and then load rate of each UPS will be 100%.

• The number of power systems can be decreased overall electricity supply solutions, minimizing the investment cost of power equipment.
• Redundancy of single power supply system can be increased, which can ensure the safe operation of loads more strongly.
• Power capacity of UPS can be expanded and dynamically increased according to different requirements. Users can expand the capacity without the need for professional intervention.

One load is powered by two independent power supply systems simultaneously, and this 2N power solution can improve the reliability of power supply during load running. Adopting modular UPS to form △2N power solution can not only ensure the 2N power level for back-end loads, but also save the usage of power equipment at the same time, and single UPS has fault tolerance. Therefore, a △2N power solution should be one of the first choices for your data center.
