APC – Galaxy VS – 20000 – 20 kVA – Three Phase Online UPS

Galaxy VS UPS — 20 kW / 20 kVA, 400 V 3-Phase (1× 9Ah Smart Modular Battery String, Expandable to 4)

Highly efficient, easy-to-deploy 20 kW, 400 V three-phase UPS designed to deliver best-in-class power protection and low total cost of ownership for edge, small/medium data centers, and commercial & industrial critical loads. Ships with 1 internal 9Ah smart high-capacity modular battery string and supports expansion up to 4 strings for extended runtime (runtime charts available in the Documents tab).

Why these fail

• Undersizing — growth planning is skipped, leading to overloads and nuisance transfers.
• Poor power quality — high THD and unstable mains create heat, stress, and premature component aging.
• Harsh short-circuit environments — installations exceed equipment withstand or bypass capability.
• Inadequate commissioning — settings, sync modes, and bypass behavior aren’t validated under load.

Our solution

• High efficiency + low distortion — input THD < 3% at full load; output THD < 1% (linear) / < 3% (non-linear).
• Wide operating window — maintains efficiency from 340…460 V (400 V nominal range).
• Built-in static bypass — robust continuity during fault/overload scenarios.
• Scalable battery architecture — 1 string installed; expand to 4 strings when runtime demands increase.
• Included 5×8 start-up — on-site commissioning support (5 days × 8 hours) to validate configuration and operation.
