The YT-UM Series (20–200 kVA) is a 3-phase input, 3-phase output UPS power supply system. Featuring a modular design and N+X parallel redundancy technology, the product covers a power capacity range spanning from 20 kVA to 200 kVA, allowing users the flexibility to configure systems and scale their investments incrementally. This UPS series is capable of effectively resolving virtually all common power-related issues—including power outages, mains overvoltage, mains undervoltage, momentary voltage sags, damped oscillations, high-voltage pulses, voltage fluctuations, voltage surges, harmonic distortion, electrical noise, and frequency fluctuations.
This product boasts a wide scope of application, providing secure, stable, reliable, and eco-friendly power protection for critical loads across various sectors, including telecommunications, finance, education, transportation, broadcasting, healthcare, and manufacturing.
The entire architecture of this UPS series adopts digital control, resulting in excellent performance indicators.
Single module capacity is 20KVA, and all modules are 2U in height; UPS modules can be added and removed online.
Features a 19-inch standard rack design, aesthetically pleasing and perfectly suited for data center applications.
When the number of redundant modules reaches two or more, system availability reaches 99.999%6, with an MTBF (Mean Time Between Failures) exceeding 250,000 hours; supports parallel operation of up to four racks, sharing battery banks during parallel operation.
Users can set the charging current; constant current, constant voltage, and float charging modes can be automatically and smoothly switched; battery capacity is selectable from 30 to 50 cells.
Large LCD display with touch functionality; 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 allows for emergency shutdown; it also features remote emergency shutdown (REPO) functionality.
"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."
