Key Features of the APC Smart-UPS VT 20kVA 400V

  1. Double Conversion Online Topology
    The UPS operates using a double conversion online design, which ensures a consistent and clean power output by converting incoming AC power to DC and back to AC. This process eliminates voltage fluctuations and ensures that connected equipment receives pure sine wave power, even during outages or poor power conditions.
  2. Scalable Runtime with Hot-Swappable Batteries
    The SUVTP20KH4B4S includes four battery modules, providing a solid runtime that can be extended by adding more modules as needed. The hot-swappable design allows batteries to be replaced without powering down the system, ensuring uninterrupted operation during maintenance.
  3. Dual-Mains Input
    With dual-mains input capability, the UPS can connect to two separate power sources, increasing availability and redundancy. This feature is particularly valuable in environments where power reliability is a concern.
  4. Built-in Maintenance and Static Bypass
    The internal maintenance bypass allows technicians to service the UPS without interrupting power to connected loads. The static bypass ensures seamless transfer to utility power in case of an overload or fault, enhancing system reliability.
  5. Parallel Capability
    The SUVTP20KH4B4S supports parallel operation, enabling multiple UPS units to work together for increased capacity or redundancy. This makes it an excellent choice for growing businesses or facilities requiring N+1 redundancy.
  6. High Efficiency and Low Cost of Ownership
    With an efficiency rating of up to 95.3% at full load, this UPS minimizes energy waste. Its “Soft Start” feature reduces the strain on electrical infrastructure—such as wires, transformers, and generators—lowering installation and operational costs.
  7. Advanced Management and Monitoring
    The system includes a network management card for remote monitoring and control via Web/SNMP. The multi-function LCD console provides real-time status updates, while customizable management cards allow for tailored functionality.
  8. Generator Compatibility
    The UPS ensures clean power delivery even when paired with a generator, making it ideal for environments with backup power systems.
