300 KVA UPS – Modular Three-Phase Online UPS 30–300KVA | Double Conversion, 0ms Transfer

Enterprise 300 KVA UPS — Scalable, Modular, Zero-Downtime Power Protection

When your operation can’t afford a single second of downtime, you need a 300 KVA UPS that’s built for the long haul. This modular three-phase online UPS scales from 30KVA up to 300KVA within a single cabinet, using hot-swappable 30KW power modules that can be added, removed, or replaced while the system stays fully online. Whether you’re protecting a growing data center, a critical telecom facility, or high-load industrial equipment, this UPS grows with you — no forklift upgrades, no service windows.

True double-conversion, always. Every watt of power your equipment receives is regenerated by the inverter, continuously filtered and stabilized. The grid never touches your load directly. In the event of mains failure or bypass switching, the transition is 0ms — invisible to every connected device.

Designed for unstable grid environments. The input voltage window runs from 207VAC to 478VAC with a frequency range of 40–70Hz, making this UPS fully compatible with generator-backed power, weak grid infrastructure, and international voltage standards (380/400/415VAC). Input current harmonic distortion stays below 3%, protecting upstream equipment and ensuring compliance with power quality standards.

Built-in overload resilience. The system handles overloads gracefully: up to 110% load for 60 minutes, 125% for 10 minutes, and 150% for 1 minute before protective shutdown — giving your systems time to shed load safely rather than cutting out abruptly.

Intelligent battery management. Selectable battery configurations of 32 to 40 battery strings (±192VDC to ±240VDC) let you tune the runtime to your exact requirements. Charging current scales with cabinet size — up to 100A for the 300KVA cabinet — with per-module charging at 10A max. Battery voltage accuracy holds at ±1% in battery mode for stable, consistent output even during extended outages.

Full visibility and remote management. Communication ports include RS-232, RS-485, USB, and two intelligent slots for optional SNMP cards, enabling integration with building management systems, network monitoring platforms, and UPS management software across Windows, Linux, and Mac.

Compact footprint for the capacity. The 300KVA cabinet measures 1100×600×2000mm and weighs 305kg — a manageable footprint for a system delivering up to 300KW of protected power. Individual 30KW modules measure 580×443×131mm and weigh 33.5kg each, simplifying logistics and field installation.

Suitable for: data centers, server rooms, telecoms infrastructure, industrial automation, precision manufacturing, medical facilities, and broadcast operations.
