Technical FAQs 4

What is an uninterruptible power supply (UPS) system?

(Uninterruptible Power Supply) system is a configuration of multiple UPS units that work in parallel to provide a more reliable and robust power protection solution.

What is a parallel redundant Type UPS (uninterruptible power supplies)?

Our parallel redundant type UPS (Uninterruptible Power Supplies) and recommended usage scenarios SANYO DENKI offers a variety of parallel redundant type UPS to suit your needs. It has a capacity of 5kVA to 20kVA, and up to four 5kVA units can be combined. It is possible to operate in parallel with one unit as a spare unit.

What is a parallel UPS system?

Parallel operation (also called load-sharing or synchronized operation) refers to two UPS units being electrically connected in parallel to share the same load. These systems use synchronization and load-sharing control to function as a single power source. ✅ Increased Capacity: Allows UPS systems to support larger loads.

Can I replace a ups without stopping the power output?

If the UPS is in parallel redundant operation, you can replace a UPS unit without stopping the power output. If the UPS has a maintenance bypass circuit, you can replace the unit during bypass operation, so there is no need to stop the equipment. 3. Our parallel redundant type UPS (Uninterruptible Power Supplies) and recommended usage scenarios
