The YT-UM30-300kVA three-phase input and three-phase output UPS adopts a modular design and N*X parallel redundancy technology. Its capacity covers various power ranges from 30kVA to 300kVA, allowing users to flexibly configure and gradually invest. This series of UPS can almost completely solve all power supply problems, such as power outages, high mains voltage, low mains voltage, voltage dips, amplitude oscillations, high voltage pulses, voltage fluctuations, surge voltage, harmonic distortion, noise interference, and frequency fluctuations.
This product has a wide range of applications, providing safe, stable, reliable, and environmentally friendly power protection for critical loads in various industries such as telecommunications, finance, education, transportation, broadcasting, healthcare, and manufacturing.
The entire architecture of this UPS series adopts digital control, resulting in excellent performance across all aspects.
Single module capacity is 30KVA, and all modules are 2U in height; UPS modules can be added and removed online.
Digital control standard cabinet appearance, aesthetically pleasing, and perfectly compatible with data center application environments.
When the number of redundant modules reaches two or more, system availability reaches 99.999%, and MTBF (Mean Time Between Failures) exceeds 250,000 hours; supports parallel operation of 4 cabinets, with shared battery packs during parallel operation.
Users can set the charging current; constant current, constant voltage, and float charging modes can be automatically and smoothly switched; the number of batteries is selectable from 30 to 50. 'LCD Color Screen Display'
Large LCD display in the cabinet with touch function, selectable Chinese/English bilingual language.
In case of emergency, it can switch to maintenance bypass power supply, allowing maintenance personnel to safely perform online maintenance; pressing the EPO button in an emergency will shut down the machine; it also has a remote emergency shutdown (REPO) function.
The centralized monitoring module has hot-swappable functionality, an RS485 communication interface, and optional accessories such as SNMP cards, relays, and dry contact cards can be installed.
