High-Frequency Rack-Mount UPS — Flagship Three-Phase Rack for Enterprise Server Rooms

The flagship class of the High-Frequency Rack-Mount family is built for the rooms where three-phase power is not optional and rack space is at a premium. Engineered as a true three-phase-in, three-phase-out, online double-conversion platform and packaged in a dense rack-mount chassis, this class carries the weight of large server rooms, network data centres, government IT rooms, hospital IT floors, university computing hubs, transportation control centres, and financial trading back-ends — and does so with the quiet authority of a system designed from the start to live inside a rack.

Built for the racks where flagship protection is the baseline

Most enterprise server rooms want online double-conversion protection; flagship protection rooms want it three-phase, in-rack, and serviceable. This class delivers true three-phase in and three-phase out, with DSP-based digital control that protects every phase and every load against every kind of mains disturbance. The chassis is sized for the densest server racks and engineered to keep working while every neighbouring system draws a deep breath.

Where it makes the difference

• Government and public-sector server rooms with three-phase distribution.

• Hospital IT floors, imaging centres, and tier-room equipment rooms.

• University and research computing hubs with consolidated three-phase IT.

• Transportation, rail, and aviation control centres with three-phase loads.

• Financial trading back-ends, securities operations, and large enterprise server rooms.

What you gain

• A true three-phase in / three-phase out online double-conversion backbone delivered in a rack-mount chassis.

• DSP-based digital control with ultra-wide input tolerance and gentle generator hand-off.

• High online efficiency with intelligent eco-mode behaviour at steady state.

• Strong input power quality with low input current distortion, easing upstream cabling and generator sizing.

• High single-phase load tolerance so partial three-phase distribution does not destabilise the system.

• A compact in-rack form that frees floor space and simplifies cable management.

• Comprehensive monitoring via a colour touchscreen and standard remote interfaces.

How the platform works for you

DSP-based digital control drives the rectification and inversion stages, with intelligent logic governing every mode transition. The result is a clean sine output that stays clean even when the input is anything but. Intelligent battery management adapts to VRLA or lithium chemistries, extends battery life, and gives accurate runtime predictions so the next surprise outage does not become a mystery. The chassis is engineered for serviceability: front-accessible boards, clean cable paths, and routine firmware updates.

Service, integration, and lifecycle

The flagship rack-mount class is supported by a global field-engineering network with regional spares and predictable maintenance schedules. It integrates with the leading DCIM and BMS platforms via standard communication interfaces, supports remote firmware management, and is designed for control-board upgradeability across generations — so a rack bought today can host the smarter control boards of tomorrow.

Frequently Asked Questions

• Is this overkill for a small closet? For small single-phase rooms, the compact tier fits better; the flagship tier is built for three-phase enterprise server rooms.

• Can multiple racks run in parallel? Yes — parallel logic is built in for load sharing and redundancy.

• How does it behave on generator power? The ultra-wide input window and gentle hand-off keep the load clean and avoid needless battery drain.

• Does it support lithium batteries? Yes — the battery subsystem adapts to VRLA or lithium banks.

• What monitoring options are available? A colour touchscreen plus standard remote interfaces expose input, output, battery, and load health.

• How is service handled? Front-serviceable components, regional spares, factory-trained engineers, and scheduled preventive maintenance.

• Is it future-proof? Modular firmware and field-replaceable control boards extend useful life across generations.

• What warranty and service options exist? A standard multi-year warranty with extended and on-site plans available globally.

Information Security and Data Protection

Role-based access, audit-friendly event logs, and encrypted remote communication where supported by your management platform protect operational data. Telemetry stays inside your network boundary by design — the platform does not relay facility data beyond the systems you have explicitly connected.
