SANTAK Castle 3K Online UPS C3KS UNI - Reliable Power for Critical Systems
The SANTAK Castle 3K C3KS UNI is a high-performance, double-conversion online UPS designed for "Long Backup" applications. Unlike standard models with internal batteries, the C3KS (Long Run Type) is engineered to work with external battery banks, allowing users to customize backup time from hours to full days based on their specific needs.
With a robust 3000VA/2700W capacity and Pure Sine Wave output, it provides the ultimate protection for servers, networking equipment, medical devices, and sensitive laboratory electronics against power surges, brownouts, and total outages.
Key Features
- Long Run Configuration: Optimized for external battery connection (72V DC) to provide extended backup periods.
- True Double Conversion: 0ms transfer time ensures your equipment never feels a power flick or interruption.
- Wide Input Voltage (100V - 300V): Operates in unstable grid conditions without constantly draining battery power.
- High Power Factor (0.9): Delivers more actual wattage (2700W) to support modern, high-efficiency servers.
- Pure Sine Wave Output: Guarantees the cleanest power quality for sensitive electronics.
- Intelligent Management: Supports RS232, USB, and optional SNMP card for remote monitoring and auto-shutdown.
