Reliable Power Protection for Critical Business Operations
The SANTAK Castle C3KS 3000VA Long Backup Online UPS is a powerful, enterprise-grade solution designed to deliver uninterrupted, clean, and stable power for critical systems. Whether you’re managing servers, network infrastructure, medical equipment, or sensitive office electronics, this UPS ensures your operations stay online even during frequent power outages and voltage fluctuations common in Bangladesh.
With a strong 3000VA / 2700W power rating, the Castle C3KS offers higher usable output than standard UPS models, making it ideal for medium to large office environments where reliability is non-negotiable.
True Online Double-Conversion Technology
The Castle C3KS uses true online double-conversion technology, meaning your equipment is always powered through the UPS inverter. Incoming AC power is converted to DC and then back to clean AC, completely isolating connected devices from power disturbances such as spikes, surges, brownouts, and frequency variations.
This ensures zero transfer time during power failure—an essential feature for servers and mission-critical systems where even a millisecond of downtime can cause data loss or system errors.
Wide Input Voltage Range – Built for Bangladesh
Electricity conditions in Bangladesh can be unpredictable. The Castle C3KS handles this effortlessly with a wide input voltage range of 100–300VAC, allowing it to operate without switching to battery during low or high voltage conditions. This not only protects your equipment but also significantly extends battery lifespan.
The UPS also supports selectable output voltages (220/230/240VAC), ensuring compatibility with a wide range of professional and industrial devices.
Long Backup Capability & Real-World Performance
Although the Castle C3KS provides a standard backup time of 15–20 minutes, it is designed as a long backup online UPS, meaning it can support extended runtime using external battery configurations. This flexibility is especially useful for offices, banks, call centers, and clinics that require longer power continuity during extended outages.
From real-world usage, IT professionals appreciate the Castle C3KS for its stable output, low failure rate, and ability to keep entire server racks running smoothly during unexpected power cuts.
