Frequently Asked Questions (FAQ)

Q1: Does the G3LUPS250KHTS include internal batteries?

A: No, this model is the “Without Internal Battery” version. It is designed to be connected to external battery cabinets, allowing for customized and extended backup runtimes based on your facility’s needs.

Q2: What is the main advantage of the Galaxy 3L over the Galaxy VS?

A: While both are highly reliable, the Galaxy 3L is specifically designed to be simpler to install and operate in medium to large buildings, offering a highly competitive price-to-performance ratio for general-purpose high-power applications.

Q3: Can I parallel multiple units of the 250kVA model?

A: Yes, you can parallel up to 5 units for a total capacity of 1250kVA or to create an N+1 redundant configuration for enhanced reliability.

Q4: How does the PF=1.0 benefit my operation?

A: A Power Factor of 1.0 (Unity) means you get 250kW of real, usable power. Traditional 0.8 or 0.9 PF UPS systems would provide less wattage for the same kVA rating, potentially requiring a larger, more expensive UPS for the same load.

Q5: Is this UPS compatible with Lithium-ion batteries?

A: Yes, the Galaxy 3L supports modern Lithium-ion battery cabinets in addition to traditional VRLA batteries, allowing for a longer service life and a smaller battery footprint.
