Small and mid-size server rooms, network closets, automation control rooms, and small branch IT closets — these are the rooms where a compact rack-mount UPS earns its place. The compact tier delivers single-phase online double-conversion protection in a shallow rack-mount chassis, with the same DSP-based digital control and intelligent battery management that anchor the larger tiers — sized for the rooms where the rack is small and the doorway is the limit.
When the closet is tight and the IT stack is critical, the wrong UPS ends up on the floor or compromises on protection. The compact tier fits in a standard rack, delivers online double-conversion protection, and runs quietly enough to sit next to an occupied workspace. From the team's perspective, the compact rack-mount looks like one product family — not one big product and several compromises.
SMB server rooms and small enterprise headquarters.
Network closets and edge communication rooms.
Small finance and insurance branch IT closets.
Small automation and process-control rooms that need clean single-phase control power.
Small commercial, retail back-office, and educational facilities.
A shallow rack-mount chassis for tight closets and small server rooms.
Online double-conversion protection for small-but-critical single-phase loads.
An ultra-wide input window that handles the small-room reality of dirty utility and modest generator power.
High online efficiency with intelligent eco-mode behaviour, even in the partial-load range.
Comprehensive protection: overload, short-circuit, over-temperature, and battery management with honest runtime predictions.
Standard remote interfaces that expose every important parameter to any common monitoring stack.
Quiet acoustics and a service-friendly footprint suited to occupied spaces.
The compact tier uses the same DSP-based digital control plane as the larger tiers — only the chassis is smaller. Single-phase input and output, online double-conversion protection, intelligent battery management, and honest runtime predictions. The result is a clean sine and a small footprint — with monitoring that a small team can rely on without standing next to the rack.
Even the compact tier deserves a real service model. It is supported by the same global field-engineering network as the rest of the family, with regional spares and remote-diagnostic options that keep truck rolls short. Integration with DCIM, BMS, and common SMB monitoring tools is straightforward, firmware updates are routine, and the control board is upgradable across generations.
How small is the rack footprint? The chassis is engineered for shallow racks and standard doorways.
Can it run quietly next to an office? Yes — acoustics are tuned for occupied spaces.
What battery chemistry is supported? The charger and management adapt to traditional or lithium chemistries.
How loud is it at low load? Fans modulate with load; quiet in normal operation.
Does it integrate with our monitoring stack? Standard remote interfaces expose parameters to the leading platforms.
Is service available at remote sites? Front-serviceable components plus regional spares keep service visits short.
Is it future-proof? Modular firmware and a field-replaceable control board extend useful life.
What warranty and service options exist? A standard multi-year warranty with extended and on-site plans.
Role-based access, audit-friendly logs, and encrypted remote communication protect operational data where supported by your management platform. Telemetry stays inside your network boundary by design.
