Eaton 93PR UPS

What it is: A modular, three-phase, transformer-free UPS for mission-critical facilities such as data centers, healthcare, commercial buildings, control centers, and process industries.
Power range / frames: Available as 300 kW, 400 kW, 600 kW, and 1200 kW frames (rated kVA = kW).
Modular growth & redundancy: Uses 60 kW hot-swappable power modules to scale capacity and build internal redundancy; supports both vertical expansion (more modules per frame) and horizontal expansion (parallel systems).
High efficiency: >97% efficiency in double-conversion mode; up to 99% in Energy Saver System (ESS) for lower energy and cooling cost.
Advanced power conversion: 3-level SiC hybrid IGBT rectifier and inverter with microprocessor-based control for high performance and reliability.
Optimized part-load efficiency: VMMS (Variable Module Management System) balances/suspends extra capacity to keep efficiency high at low loads—ideal for redundant architectures.
Parallel resiliency: Hot Sync algorithm removes single-point-of-failure risks in parallel operation by allowing each module/UPS to contribute independently.
Battery flexibility: Compatible with Lithium-ion, VRLA, and Ni-Cad battery systems; battery bus 360–700 Vdc; supports common battery configurations.
Generator-friendly input: High input performance with PF >0.99 and THDi <3% (at 100% load); rectifier soft-start/ramp-up settings support generator operation.
Electrical (typical):

Input: 380/400/415 V; wide input range 301–478 V (L-L) / 175–276 V (L-N)
Output: 380/400/415 V, ±1% steady-state regulation; overload 110% (60 min) / 125% (10 min) / 150% (1 min)

Fast service / low downtime: Hot-swappable power modules, static switch module, and communication module; MTTR can be as low as ~5 minutes for replaceable modules.
Operations & monitoring: Large 7-inch color touchscreen, LED light bars visible from a distance, event/energy tracking, and integration with virtualization platforms via power management software.
Connectivity: Multiple communication slots; USB device/host; alarm inputs, dedicated EPO, and relay outputs; optional cards for SNMP, Modbus TCP/RTU, BACnet IP, etc.
Practical installation: Top/bottom cable entry, standard dust filters; operating environment 0–40°C (no derating), IP20.
