Enterprise-Grade Power Protection with Flexible Long Backup Support
The SANTAK Castle C6KS 6000VA Long Backup Online UPS is a robust, high-capacity power protection solution engineered for businesses that cannot afford downtime. Designed for servers, data centers, financial institutions, medical equipment, and industrial applications, this UPS delivers continuous, clean power even during prolonged outages—making it an ideal choice for Bangladesh’s challenging power conditions.
With a powerful 6000VA / 5400W output, the Castle C6KS supports heavy electrical loads with ease, ensuring that your mission-critical systems remain fully operational.
True Online Double-Conversion Technology
At the core of the Castle C6KS is true online double-conversion technology. Unlike line-interactive or offline UPS systems, this model continuously converts incoming AC power into DC and then back into stable AC power. This process completely isolates connected equipment from voltage fluctuations, surges, spikes, and electrical noise.
The result is zero transfer time, ensuring seamless operation for sensitive electronics like servers, routers, switches, and medical devices—where even a split-second interruption can cause serious damage or data loss.
Designed for Unstable Power Environments
Bangladesh experiences frequent voltage variations and sudden power failures. The Castle C6KS handles this effortlessly with a wide input voltage range of 120–275VAC, allowing it to operate without switching to battery during most power irregularities. This significantly reduces battery wear and increases overall system efficiency.
The 220VAC pure sine-wave output ensures safe and stable power delivery, fully compatible with professional and industrial-grade equipment.
Long Backup Flexibility for Real-World Needs
Unlike standard UPS systems with fixed runtime, the SANTAK Castle C6KS is a long backup UPS, meaning backup time depends on customer-configured external batteries. This flexibility allows businesses to design power solutions ranging from short emergency backup to hours of uninterrupted runtime, depending on operational requirements.
IT managers and engineers appreciate this flexibility, especially in environments like data centers and hospitals where extended backup is essential.
