The YT-UM series 50-600kVA modular UPS adopts digital control, modular design, and N+X parallel redundancy technology. Product capacity covers various power ranges from 50kVA to 600kVA, facilitating flexible configuration and gradual investment for users. Up to four units can be paralleled up to 2400kVA.
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.
Employs digital control, offering superior performance and capable of handling completely unbalanced loads.
Overall efficiency up to 96%<sup>6</sup>
Output power factor of 1.
The centralized control unit is redundantly connected in parallel; failure of one unit does not affect overall operation. N+X parallel redundancy achieves 99.999% availability<sup>6</sup>
The centralized monitoring module is hot-swappable and uses centralized bypass power supply, improving the bypass power supply capacity.
Features EPO (Emergency Emergency Power Outage) functionality, enabling remote emergency shutdown (REPO).
Modular design; users can flexibly increase the number of modules.
Short downtime for maintenance; in case of an emergency, maintenance personnel can safely perform online maintenance.
Touchscreen color display provides comprehensive UPS status information, warning messages, and fault information.
Battery capacity and charging current can be set on the LCD screen, enabling automatic and smooth switching of charging modes.
Utilizes advanced two-stage, three-phase intelligent charging, balancing fast charging with extended battery life.
A wide range of optional accessories, including SNMP cards, relays, and dry contact cards.
Utilizes a standard 19-inch rack, perfectly matching data center application environments.
Parallel battery sharing significantly reduces the number of batteries required.
30-50 external batteries are available, allowing users flexible battery configuration.
