400 KVA UPS — High-Power Modular Protection Built to Scale

When your operation demands 400KVA of uninterrupted, clean power, you need more than a conventional UPS — you need infrastructure that scales with you. The RM50 400 is a high-frequency, true double-conversion three-phase online UPS that starts at 50KW and expands to 400KW within a single cabinet using hot-swappable 50KW power modules. No service windows. No forklift swaps. No downtime. Whether you are commissioning a new data center, expanding an existing one, or protecting high-value industrial or medical equipment, this 400 KVA UPS is engineered to grow alongside your operation.

True double-conversion means your load never touches the grid directly. Every watt delivered to your equipment is continuously regenerated by the inverter — filtered, stabilized, and isolated from voltage fluctuations, surges, brownouts, and frequency instability. In the event of mains failure or a bypass transition, the switch is 0ms, completely invisible to every connected device.

Built for the world’s most demanding grid conditions. With an input voltage range of 138–485VAC and a frequency window of 40–70Hz, this UPS operates reliably on weak grids, generator-backed supplies, and international voltages (380/400/415VAC) without derating. Input power factor exceeds 0.99 and input current harmonic distortion stays below 3% on non-linear loads, protecting upstream infrastructure and ensuring clean power draw throughout.

96% efficiency — more power delivered, less wasted. Compared to older-generation UPS architectures, the RM50 400 achieves up to 96% efficiency in normal online mode, reducing heat output, lowering cooling costs, and cutting electricity bills at scale. Over the lifetime of a 400KVA installation, this efficiency advantage translates into meaningful operational savings.

Modular architecture means maximum uptime during maintenance. Each 50KW power module is hot-swappable — you can insert, remove, or replace modules with the system fully energized. This eliminates planned maintenance windows entirely and reduces mean time to repair to minutes. Up to 8 modules populate the RM50 400 cabinet, and the system supports parallel configurations for N+1 or N+X redundancy as your criticality requirements grow.

Intelligent overload handling protects your loads gracefully. Rather than cutting out abruptly under overload, the system manages stepped overload conditions: sustaining 110% load for up to 60 minutes, 125% for 10 minutes, and 150% for 1 minute before transitioning to bypass — giving connected equipment time to shed load or shut down safely.

Flexible battery configuration for any runtime requirement. Battery string count is selectable from 30 to 50 units, with corresponding DC bus voltages from ±180VDC to ±300VDC. This lets you precisely tune backup runtime to your application, from short bridging intervals in generator-backed facilities to extended autonomy in standalone protection scenarios. Per-module charging current reaches 20A maximum.

Enterprise communication and monitoring as standard. The RM50 400 includes CAN bus, RS-485, a dedicated network port, dry contact port, parallel port, LBS port, intelligent expansion slot, and temperature sensor port. Optional SNMP integration enables full remote monitoring and management through network management platforms, building management systems, and web browsers across Windows, Linux, and Mac environments.

Comprehensive protection functions built in. Short circuit, overload, over-temperature, output over/under-voltage, battery undervoltage, fan fault, bypass flow backward, and lightning surge protection are all included as standard. Alarm functions cover mains abnormal events, overload conditions, UPS fault states, and battery undervoltage warnings — keeping your operations team informed before a problem becomes a failure.

Ideal for: large data centers and server rooms, enterprise network infrastructure, industrial automation and control systems, telecoms and broadcast facilities, precision medical equipment, and any mission-critical environment where 400KVA of protected power is non-negotiable.

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

Tyne Tingey — Wed, 01 Apr 2026 13:46:15 +0000

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.

High Efficiency & Power Factor: Features a high input power factor (≥0.99) and efficiency over 90%, significantly reducing operational costs and heat dissipation.
Cold Start Capability: Flexibility to start the UPS directly from the battery bank even when utility power is unavailable.

Reliability for Critical Applications

This 20kVA system is specifically tailored for data centers, medical facilities, and industrial automation.
With a built-in 192Vdc battery management system and intelligent protection against overloads and phase
sequence errors, it represents the gold standard in business continuity.
