Autonomy Backup Examples

UPS 10kVA with 7kW load:

With 1 Lithium Internal Module x 50Ah = 20 Minutes
With 2 Lithium Internal Module x 50Ah = 40 Minutes
With 3 Lithium Internal Module x 50Ah = 60 Minutes

UPS 20kVA with 14kW load:

With 2 Lithium Internal Module x 50Ah = 20 Minutes
With 3 Lithium Internal Module x 50Ah = 30 Minutes

UPS 30kVA with 21kW load:

With 2 Lithium Internal Module x 50Ah = 13 Minutes
With 3 Lithium Internal Module x 50Ah = 20 Minutes -PH

Key Features:

  • Advanced Battery Technology: Built-in lithium-ion battery with hot-swappable modular design ensures uninterrupted power supply.
  • Efficiency Matters: Achieve an AC/AC efficiency of up to 94% with an output power factor of 1.0.
  • Adaptive Input: Wide input voltage range (120-268V L-L) and input frequency range (40-70Hz) for enhanced grid adaptability and extended battery life.
  • Robust Overload Capacity: The inverter supports long-run operation at 105% load and 10 minutes at 130% load, ensuring reliability during peak demand.
  • Enhanced Reliability: Internal air channel design directs hot air away from sensitive components, prolonging the UPS’s service life. Lightning and surge protection safeguard against voltage spikes, and battery reverse connection protection ensures system reliability.
  • Multiple Configurations: Benefit from advanced battery charging, cold start functionality, and the option for parallel installation (N+1) of up to 10 units.
  • User-Friendly Interface: Navigate through settings with ease using the colorful 4.3-inch touch screen with LED indicators and a multi-language interface. Dual DSP control enhances performance.
  • Customizable Settings: Access various configuration options, including input, output, bypass, batteries, and communication settings, to suit your specific needs. A large memory stores up to 10,000 events.
  • Communication Capabilities: Integrate seamlessly with diesel generators and remote monitoring systems via advanced communication features.
  • Cutting-Edge Technology: Electrical and physical double isolation design minimizes fault scope. Latest-generation IGBT and three-level technology ensure low harmonics and high efficiency.
  • Compact Design: High power density design saves installation space, with a small footprint for 30kVA units. High input power factor reduces grid pollution and costs.
  • Energy-Saving Features: AC/AC efficiency of up to 94% and ECO mode efficiency of up to 98.5% contribute to significant cost reductions.
  • Self-Load Test: Simplify commissioning with a self-load test function, eliminating the need for temporary loads and cables.
  • Easy Serviceability: Minimize downtime with an architecture designed for easy service, featuring wheels for mobility.
  • Frequency Converter: Switch between 50Hz-60Hz or 60Hz-50Hz converter mode and disable the static bypass and DC power supply when needed.
  • Preventative Maintenance: Key components pre-alarm function alerts you to system faults and the need for service, ensuring uptime.
