Reliable backup for our office servers! We've been using the Santak Castle 6kVA for a few weeks now and it's really heavy duty. We experience frequent voltage fluctuations here, but this UPS handles it smoothly. The Online Double Conversion technology gives us peace of mind knowing our servers are safe. Installation was straightforward and the build quality is solid. It's a very practical investment for businesses looking for quality without the premium price tag of other brands. Highly recommended for local setups
