Product introduction:
LIRUISI's N series three-in, three-out UPS adopts modular design and N+X parallel redundancy technology, and the product capacity covers each power segment between 20kVA and 300kVA, which is convenient for users to flexibly configure and gradually invest. This series of UPS can almost completely solve all power supply problems, such as power failure, mains high voltage, mains low voltage, voltage instantaneous drop, amplitude reduction oscillation, high voltage pulse, voltage fluctuation, surge voltage, harmonic distortion, clutter interference, frequency fluctuation and other power supplies.
Uninterruptible power supply modular UPSN series 300KVA features and advantages:
Smart management: Modern modular high-frequency UPS usually has intelligent monitoring functions, which can monitor device status in real time and manage it remotely through the network. This helps improve device availability and maintenance efficiency.
way of working:
Three-in, three-out/three-in, single-out, double-conversion online work modular model operation.
Product Features:
Modular UPS-N series 20-300KVA UPS This series UPS is a high-power three-in, three-out UPS power supply, 20-300KVAUPS, N60KVA/90KVA, N100KVA/150KVA, N200KVA/300KVA output can be connected to a fully unbalanced load, when the output is connected to an unbalanced load, the input current is balanced in three phases, which can balance the load of the three-phase power grid.Digital control, high power density modular design, 19-inch standard cabinet, N+X parallel redundancy, intelligent battery management, LCD color screen display, safe and convenient maintenance, intelligent managementThree-in, three-out pure online double-conversion product, supporting 380/400/415V, 50/60Hz power grid system, providing the best power supply quality and load protection.The rectifier adopts IGBT, with PFC function, input power factor up to 0.99, input harmonic current less than 3%, and the efficiency of the whole machine is ≥ 94.5%, which is green and environmentally friendly, high efficiency and energy saving.Fully digital dual DSP control.Integrated independent main input open, output empty open and maintenance bypass open for easy user wiring.The number of battery packs can be set ± 15~±25 cells, which is convenient for the need to flexibly adjust the number of battery cells when individual battery failures need to be maintained and replaced in the future.With the autonomous aging mode, the system can be fully loaded to test, eliminating the workload of renting a large load tank and load box engineering construction.
