Kehua Three In One Out UPS Power Supply YTG3115 Data Center Stable and Uninterruptible Power Supply Equipment

Description :

  YTG3115 is a three in single out uninterruptible power supply designed specifically for critical loads, mainly to solve the damage caused by power interruption and voltage fluctuations to data centers and precision instruments. This UPS power supply adopts online dual conversion technology to ensure high stability and purity of the output power supply. It is suitable for working conditions that require single-phase 220V output but are connected to three-phase 380V mains power, effectively balancing the load of the three-phase power grid and preventing excessive zero line current. It is an ideal power protection solution for small and medium-sized computer rooms, medical equipment, and industrial control systems.

  The YTG3115 UPS power supply model from Kehua has standard three-phase input and single-phase output interfaces, with a wide input voltage range and strong adaptability. The typical rated capacity is 15kVA/12kW (subject to nameplate), with high output power factor and strong load capacity. The device has built-in intelligent battery management function, supports long-term delay configuration, and complies with national standards such as GB/T 7260.3. The compact body design, optimized heat dissipation ducts, good noise control, and multiple protection mechanisms such as overvoltage, undervoltage, overload, and short circuit ensure stable operation in harsh power grid environments. It has passed common safety certifications such as CE.

  When selecting, it is necessary to clarify the nature of the load. YTG3115 is suitable for linear loads such as computers, servers, network devices, as well as some inductive loads. If the load power factor is extremely low or the surge current is extremely high, the UPS capacity needs to be appropriately amplified. Compared with single input and single output models, the three input and single output structure is more suitable for connecting to three-phase distribution cabinets, avoiding the problem of power grid imbalance caused by single-phase power supply; Compared with the three in three out model, its output is single-phase, which is more in line with the direct connection requirements of end single-phase electrical equipment, without the need for additional conversion, simplifying the wiring structure, and improving power supply efficiency.

  When installing YTG3115 UPS power supply, it is necessary to ensure good ventilation, reserve sufficient heat dissipation space around, and ensure reliable grounding. In daily maintenance, the voltage and internal resistance of the battery pack should be checked regularly. It is recommended to conduct a charge and discharge test every 3-6 months to activate battery activity and extend its service life. Pay attention to keeping the environment dry and clean, and avoid dust accumulation that affects heat dissipation. If the device alarms, the fault should be checked according to the panel indicator lights or monitoring software prompts. Common issues include battery aging, overload, or input abnormalities. Timely handling can ensure the continuity of power supply in the data center. Kehua YTG3115 UPS Product Parameters
