Pros: The transfer is natural to the design of the UPS. Provides very high reliability and maximum redundancy as four total power sources are available to the critical loads: 1) AC Main Input Source 2) UPS A Battery Bank 3) UPS B Battery Bank 4) Bypass Source Cons: Each unit must be correctly sized to handle the entire load.
Each 12kW BladeUPS module has redundant internal battery strings that provide 4.8 minutes of runtime at full load, 13 minutes at 50-percent load (240V @ 100Ah per string). …
The system is N+1 redundant if the "spare" amount of power is at least equal to the capacity of one system module; the system would be N+2 redundant if the spare power is equal to two system modules; and so on. Parallel redundant systems require UPS modules identical in capacity and model.
Notice we are using two separate terms. "Parallel" and "Redundant", since each refers to a different benefit of the system. A) To be specific, a simple Parallel system can have an output Automatic Transfer Switch, such as the diagram bellow: Two UPS working in parallel but without redundancy since both supply a common ATS.

The parallel redundant configuration is made up of at least two UPS devices connected to the equipment. Power goes through the UPS devices before it reaches the equipment. Power going into the equipment goes …
To make a redundant static uninterruptible power supply (UPS) configuration such as pictured below, I have seen warnings in UPS manuals that each UPS is to be connected to its own battery bank. ... the battery chargers in the two UPSs may interfere with each other, and may not properly charge the battery bank. ... 60.2k 1 1 …
2. Parallel UPS Configuration. In a parallel UPS configuration, two or more UPS systems are connected in parallel to provide redundancy and increased capacity. Each UPS unit operates independently and shares …
There are two main configurations: Parallel-Capacity (N) where the total load demand is met by a number of UPS without the provision of any redundancy. Parallel-Redundant …
Configuration of Parallel Redundant UPS and Battery Plants. UPS 101 - Knowledgebase. When critical loads require the highest level of protection, redundant systems offer back-up protection for the back-up devices. Industrial - Petrochemical - Communications - Emergency Services - Utilities - Banks - Data Centers - Hospitals - Phone Systems -
One of the key benefits of a parallel redundant UPS system is it stability to provide high availability and fault tolerance. In a parallel redundant configuration, the UPS modules are designed to share the load equally, and Each module has enough capacity to handle the entire load in the event of a failure of another module.

The impedance of the bypass paths need to be controlled in a parallel UPS system. When operating in bypass mode, the parallel load sharing is …
"2N" Configuration. The next step in UPS redundancy utilizes two independent "N" systems to support an "A" side and a "B" side power source for the critical load. In this case, a failure of the "A" side system would typically not affect the "B" system. This would be considered a "2N" UPS system. The critical load should either be a dual-corded power supply system …
The N stands for a UPS module while +1 stands for an additional or spare UPS module. Due to this, an N+1 UPS configuration has at least two UPS modules connected to a device. For computer servers requiring six UPS modules, an N+1 UPS configuration means the system will have a total of seven UPS devices for use.
Parallel redundant or "N+1" configurations (see figure) allow for the failure of a single UPS module without requiring that the critical load be transferred to the utility source. This …
Note how the parallel UPS''s share the load. In this configuration the load rating is made up of an ''n'' UPS unit, each supplying 1n of the load rating. ... In a two block parallel redundant system single phase fault clearing capability is increased from about 2,5 to 5,6 In and three phase fault clearing capability is increased from about 2 ...
The diagram shows a typical parallel configuration with two three-phase UPS modules. In normal operation, AC power flows from the utility source to each UPS—one input into the rectifier and one into an internal bypass. The UPS converts incoming AC power to DC and then back to AC,
There are two common ways N+1 can be achieved: paralleling multiple unitary UPSs together or deploying a single UPS frame with multiple internal modules configured for …
The parallel redundant system consists of two identical UPS modules, a parallel cabinet, and one or two battery racks or cabinets. The parallel cabinet consists of two module …
The diagram shows a typical parallel configuration with two three-phase UPS modules. In normal operation, AC power flows from the utility source to each UPS—one input into the …
This could be supported with a traditional, single-unit 120kVA UPS system. For redundancy, though, two such units would be need to be paralleled to supply the load, creating a large system with a total capacity of 240kVA. ... The UPSs share the load equally. Fig. 2: De-centralised UPS system with three modules ... In this article we have seen ...
Similarly, when the UPS system needs to run on batteries, each UPS will still share the load as each module has its own battery set, rather than a shared common battery. If any of the UPS modules in a parallel redundant configuration fails or experiences an internal fault, it automatically disconnects from the output AC busbar, while the ...

Running two or more UPS in parallel (and thus configuring a parallel UPS system) enables customers to either add redundancy or greater capacity. There are, therefore, two primary types of parallel UPS configuration: parallel-redundancy and parallel capacity UPS.
