Double Conversion Online Technology
The DS-UPS02K48-R/TJS adopts a Double Conversion Online design, which completely isolates the load from power grid fluctuations. With Input Power Factor Correction (PFC) technology, it achieves an input power factor of up to 0.99, offering absolutely stable output voltage. The switchover time from AC operation to battery operation is 0ms, ensuring that your sensitive devices will not experience any power interruption.
Smart Battery Management and Charging
Hikvision incorporates a three-stage charging system (constant current, constant voltage, and floating), which maximizes the lifespan of VRLA batteries. The UPS features 4 batteries of 12V/9Ah, providing a 48V DC system. The typical recharge time to 90% capacity is 4 hours, while there is the option to extend the backup time through external battery packs for even more demanding applications.
Advanced Digital Control and Security
The system is based on digital control which enhances the stability and reliability of the unit. It includes comprehensive protections, such as overheating protection, output short-circuit protection, overload protection, and battery under-voltage warning. In addition, the power-on self-diagnostic function automatically checks the status of the UPS at startup, ensuring that all systems operate flawlessly before taking on the load.
Flexibility and Generator Compatibility
Thanks to the wide input voltage range (110-300Vac) and frequency (40-70Hz), the UPS operates reliably even in environments with unstable power supply. It is fully compatible with various types of fuel generators, making it ideal for installations in areas with frequent fluctuations. The Pure Sinewave output ensures that even the most demanding motors or medical devices will operate without issues.
ECO Mode and Energy Efficiency
To reduce operating costs, the UPS supports ECO mode, which improves energy efficiency when the network quality is good. With an efficiency of up to 91% in AC mode, the DS-UPS02K48-R/TJS minimizes energy losses. At the same time, the digital processor ensures that the system will immediately return to online mode if any abnormality in the input voltage is detected.
Full Information via LCD Display
The built-in LCD screen provides all critical real-time information, such as input/output voltage and frequency, load percentage, battery voltage, and internal temperature. It also displays the remaining backup time, allowing users to manage their tasks safely. With a noise level of below 50dB and a weight of 19.5kg, it is a robust and silent solution for rack or tower installation.
