Why is lithium battery suitable for UPS battery?

Mar , 22 2024

1. High energy density: Lithium batteries have high energy density, that is, batteries can store more energy per unit mass. This means that the relatively small size and weight of lithium batteries can store more power. For UPS applications, this is important because it means that lithium batteries can provide longer backup times. 2. Long cycle life: The life of lithium batteries is usually longer...

Test, use and maintenance of battery for UPS uninterruptible power supply

Mar , 30 2024

UPS battery occupies a very important position in UPS power supply equipment. At present, the maintenance-free sealed lead-acid battery widely used in small and medium-sized UPS power supplies accounts for as much as 1/4 to 1/2 of the total cost of UPS power supplies. Not only that, the actual maintenance also shows that more than 50% of UPS power failures are related to UPS batteries. Regardless ...

Measures to suppress harmonics

May , 11 2024

The fundamental cause of harmonic generation is due to nonlinear loads. When the current flows through the load and does not have a linear relationship with the applied voltage, it forms a non sinusoidal current, resulting in harmonics. The suppression of harmonics in the power system is to reduce or eliminate the harmonic current injected into the system, in order to control the harmonic voltage ...

How Low Frequency UPS Safeguards Critical Information

May , 11 2024

What is a Low Frequency UPS? A Low Frequency Online UPS is a sophisticated power protection device that utilizes double conversion technology to provide continuous and clean power to connected equipment. Unlike traditional Offline UPS, where the load is directly powered by the mains until a power failure occurs, it continuously powers the load through an inverter, ensuring a seamless transition be...
