What it is: A large-scale, modular 3-phase online double-conversion UPS designed for modern data centers, lithium-ion compatible and optimized for high efficiency and serviceability.
System capacity: 1500 kW or 1800 kW frame options; scalable via 125 kW hot-swappable UPM power modules.
Parallel scalability: Up to 4 systems in parallel for a maximum of 6 MW.
Efficiency: >97% in double-conversion mode; up to 99% with Energy Saver System (ESS).
Fast service / low MTTR: Online replaceable UPM modules with MTTR as low as ~5 minutes (service continuity).
Input performance (generator friendly): High input power factor >0.99 and low harmonics THDi <3% at full load.
Electrical (typical):
Input: 380/400/415 V, 50/60 Hz; wide input voltage window (L-L and L-N ranges supported).
Output: 380/400/415 V, 3-wire or 4-wire; voltage regulation ±1% (steady state); low distortion (<1% linear / <3% non-linear).
Overload: 125% for 10 minutes.
Battery compatibility: Supports Lithium-ion, VRLA, and Ni-Cad; battery bus 360–640 Vdc; supports common battery configurations; charging methods include BMS/ABM/float options.
Data-center-friendly mechanics: Rear or top exhaust options; compact UPM form factor (4U module height).
Monitoring & connectivity: Large color touchscreen with clear status/energy tracking and visible LED status bars; supports common protocols (e.g., HTTP(S), SNMP, Modbus TCP/RTU, BACnet IP) via optional communication cards; compatible with power management software for virtualized environments.
Energy-aware capability (optional): With upgrade kits and lithium storage, can support applications such as peak shaving, time-of-use optimization, demand response, and frequency regulation.
