The Importance of UPS Maintenance Plans and Periodic Inspections
It is important to remember that the UPS system is an essential device and is used as a backup power supply in the event of a power failure. The UPS is the most direct source of stored energy. The device must be operated to avoid interruptions and downtime.
Modern power electronics and manufacturing techniques have resulted in the most powerful UPS systems we have today. To maintain its efficiency it is essential to keep UPS in a good condition and charged with a good battery. You can buy high-quality zebra qln220 batteries from various online sources.
Regardless of whether the UPS is a monoblock or modular UPS design, the system includes a number of advanced monitoring and management systems designed to increase efficiency and operational life.
As complex as it is, and since some firmware may contain predictive algorithms, the fact is that uninterruptible power supplies have consumables that need to be checked and replaced regularly.
If consumables are not replaced due to operating and maintenance budgets, damage to the uninterruptible power supply is unavoidable.
In a UPS system, the main consumption is the battery. This will most likely be a valve-regulated lead-acid battery (VRLA). UPS lithium batteries are gaining popularity, but overall, VRLA batteries are still the most widely used.
When we consider a lead-acid battery, the time it takes to replace it depends on several factors, including its lifetime, the ambient temperature in the operating room, and the number of charge and discharge cycles the battery has undergone.
UPS batteries, most single-phase and some three-phase UPS systems use 5-year VRLA batteries with the desired lifespan. This means the battery is designed for a life of up to 5 years when operated at 20-25°C and a number of charge/discharge cycles (typically 300-400).
