    • Incorporates an isolation transformer that fully separates input and output circuits, offering superior protection for sensitive or irregular loads.
  4. Control designed to withstand all kinds of loads:
    • Features a robust control mechanism capable of supporting inductive, capacitive, non-linear, and other demanding load types without performance degradation.
  5. Intelligent battery management to prolong battery lifecycle:
    • Optimizes charging, discharging, and monitoring processes to extend battery life and ensure consistent backup performance.
  6. Independent ventilation enhances durable operation under harsh environment:
    • Uses a dedicated ventilation structure to maintain stable thermal performance, enabling reliable operation even in dusty or high-temperature environments.
  7. Adjustable battery numbers:
    • Allows flexible configuration of battery quantities to meet different backup time requirements and installation needs.
  8. Accept dual-mains input:
    • Supports two independent AC input sources, enabling higher power availability and easier integration into diverse electrical infrastructures.
  9. Parallel operation with up to 4 units (option):
    • Offers optional parallel capability to increase output capacity or provide redundancy for mission-critical applications.
  10. Varieties of communication options available:
    • Supports multiple communication interfaces, enabling remote monitoring, control, and seamless integration into management systems.
  11. Optional 7″ touch LCD:
    • Provides a large, intuitive touchscreen interface for easier configuration, monitoring, and system diagnostics.
  12. Reverse phase frequency operation and supports non-neutral input:
    • Allows flexible phase and frequency configuration and can operate without a neutral line, making it adaptable to unconventional or special power environments.

Applications

  1. Industrial Manufacturing and Automation:
    • Ideal for powering motors, CNC machines, PLCs, and heavy inductive loads thanks to its galvanic isolation transformer and robust load-handling capability.
  2. Oil & Gas and Petrochemical Facilities:
    • Provides stable, isolated power for hazardous or electrically noisy environments where equipment reliability and electrical protection are critical.
  3. Medical and Laboratory Equipment:
    • Ensures clean, disturbance-free power for sensitive imaging systems, analyzers, and diagnostic instruments requiring strict electrical isolation.
  4. Data Centers and Server Rooms:
    • Maintains uninterrupted, conditioned power for IT infrastructure while supporting parallel redundancy and flexible monitoring interfaces.
  5. Transportation and Infrastructure Systems:
    • Supports stable operation of signaling, control, and communication equipment in rail, metro, airport, and highway facilities exposed to grid instability.
  6. Power Utilities and Substations:
    • Suitable for harsh electrical environments, offering immunity to grid disturbances and compatibility with dual-mains and non-neutral input systems.
  7. Telecom and Network Equipment:
    • Provides reliable, high-quality power for base stations, network hubs, and communication systems, even under frequent voltage fluctuations.
