Do I need uninterruptible power supplies (UPS) in parallel redundant configuration?
Contact us today! Assuming you want to ensure, that the electricity supply to your "mission critical" computer system is not interrupted, under any condition, you need to use Uninterruptible Power Supplies (UPS) in Parallel Redundant Configuration.
Can you connect batteries in an uninterruptible power supply (UPS) system?
When connecting batteries in an uninterruptible power supply (UPS) system, you have the option to connect them in series or in parallel. The main difference between these two configurations lies in how they affect the voltage and current of the UPS system.
Does a parallel ups work if a single unit fails?
In practice you get slightly more power out of two units in parallel than a single unit of the same size. Each UPS requires a 'parallel' interface board fitting. If one of the units fail the load will be dropped back to bypass as they are in effect working as a single unit.
What are the options for a parallel UPS system?
Many options are available for parallel UPS systems, such as: Wraparound maintenance bypass, to allow loads to keep running (off straight utility power) even if the parallel system is unavailable, such as during a natural disaster Redundant breakers in the tie cabinet, to permit maintenance of the primary breakers without turning the system off
What is the difference between monoblock and uninterruptible power supplies?
Most uninterruptible power supplies above 10kVA have the facility for parallel operation. This means that two or more UPS systems can be connected in parallel to provide N+X resilience or increased total capacity. Monoblock UPS systems are fixed capacity systems.
Why do you need a parallel ups inverter?
By running two or more UPS Inverter units with parallel operation function in parallel, even if a UPS fails, the other UPS Inverter units can continue to supply power, significantly improving the reliability of the power supply.
