True Online Double-Conversion Technology
Unlike conventional backup solutions, the SANTAK Castle C3K continuously processes incoming power, isolating connected devices from spikes, surges, and electrical noise.

The wide input voltage range of 100–300VAC allows it to operate efficiently even in areas with extreme voltage instability—minimizing battery usage and extending battery lifespan.
The regulated output voltage (220/230/240VAC) ensures compatibility with standard electrical requirements across Bangladesh.
Designed for Real-World Business Use
Based on real usage in offices and IT environments, users value the Castle C3K for its stable output, quiet operation, and compact professional design. The standard backup time of 15–20 minutes provides sufficient time to safely shut down systems or maintain operations during short outages.
