Uninterruptible Power Supply (UPS)
UPS systems bridge power failures and thus ensure security of supply, especially for critical infrastructures such as data centers. In addition, a UPS system protects connected loads from mains events such as harmonics, overvoltages or frequency fluctuations.
Power When you Need it Most
All UPS systems consist of power electronics that regulate load management and an energy store (battery system). There are a variety of models and specifications in the UPS market.
Proper planning and configuration is important to find the right UPS system for your needs. Power outages are annoying and can be expensive, especially for businesses that rely on a constant power supply. An unplanned power outage can result in loss of production, loss of data, or other damage to your equipment. To avoid this type of service interruption, or at least to minimize its risk, it is advisable to invest in a UPS (Uninterruptible Power Supply) system.
The battery is the heart of any UPS system and the right choice is critical to the reliability and performance of your UPS system. With regard to the battery system for the UPS system, there are different energy storage systems based on lead-acid batteries (valve-regulated lead-acid - VRLA), lithium-ion batteries (Li-Ion) or capacitors (supercapacitors). When choosing a suitable battery, it is important to know the advantages and disadvantages of each. With the expertise of High Knowledge, we support you in choosing the right UPS battery.
UPS technology for data centres and server rooms
Online UPS and double conversion
In normal operation, an online double-conversion UPS supplies loads through a rectifier and inverter, isolating its output from many mains disturbances. Standby and line-interactive systems have different transfer and regulation characteristics; selection depends on the protection required by the connected IT.
Power and runtime
Active power in kW, apparent power in kVA, load profile and expansion allowance must be considered together. Battery sizing depends on the required runtime, including ageing, ambient temperature and recharging. Available capacity during maintenance or a module failure matters too.
Redundancy and maintenance bypass
Modular systems, N+1 reserve and separate A/B supplies are distinct elements of an availability concept. A maintenance bypass enables work on the UPS but does not by itself provide equivalent power conditioning. Switching procedures and remaining protection must be documented.
Coordination with backup generation and IT
Generator compatibility, restart behaviour, battery charging and protective devices require coordinated design. Load, battery and fault signals feed into monitoring. Handover includes agreed functional tests, operating documentation and a maintenance plan.
