Santak C3KR (2021) Standby UPS 3kVA

Product details

The Santak Castle Series C3KR (2021) UPS employs pure online double-conversion technology to provide 24/7 uninterrupted power protection for critical equipment. With an ultra-wide input voltage range of 110-300V, it effectively filters grid noise and adapts to generator power, maintaining stable output even in harsh electrical environments. Its 0.9 high output power factor increases load capacity by 28%, and expandable battery modules enable up to 12 hours of backup power, meeting continuous operation needs for financial outlets and branch offices. The unit features an intelligent temperature control system for stable operation in 0-40°C environments, along with corrosion-resistant design and power component protection to extend service life.The compact 2U rack structure with a depth of only 87mm perfectly fits standard IT cabinets, saving 50% installation space. Equipped with digital active power factor correction technology, input harmonics are less than 3%, compliant with IEEE standards and EU environmental certifications. Double conversion efficiency reaches 95%, significantly reducing energy costs. Supports multi-dimensional intelligent management, standard USB/RS232 interfaces, and programmable dry contacts, compatible with MODBUS, SNMP protocols. Optional network monitoring card enables remote management via mobile devices. Unique battery cold start and auto-restart functions ensure rapid power recovery after unexpected outages.Ideal for scenarios with stringent power quality requirements such as small to medium-sized data centers, industrial automation production lines, and medical imaging equipment, building a reliable power defense for critical devices.
