  • Permissible 100% load unbalance
  • High overload capacity
  • Superior protection
  • N+X redundancy parallel
  • Powerful monitoring platform
  • Advanced battery management (ABM)
  • Built-in output isolation transformer

Features

High reliability
  • Intelligent digital control
  • Permissible 100% load unbalance
  • Built-in output isolation transformer prevents harm to equipment that is caused by DC components of UPS output voltage,  reduces neutral to earth voltage and decreases the direct interference from harmonic currents of loads to improve UPS reliability
  • Full isolation of input and output avoids risk of DC sneaking into loads
  • High overload capacity
  • Batteries are directly connected to a BUS line, and output has strong impact resistance capacity
  • Intelligent self-diagnosing function and superior protections
  • Advanced parallel redundant configuration allows users to multiply capacity and uptime for future expansion by adding additional UPS systems
  • Features ECO mode and EPO (Emergency Power Off) mode
High usability and availability
  • Three/three-phase models for 380/400/415V, 50/60Hz grid systems
  • Unique ventilation design, compact whole structure for small footprint
  • Similar modular design makes field maintenance quick and easy
  • Front access makes maintenance and replacement easy (50-120kVA)

 

  • Abundant historical log (10,000 records) available for future checks
  • Flexible and optimized battery number design (28-32pcs optional)
  • Strong compatibility, suitable for all kinds of loads
  • 5.7inch LCD touch screen with friendly human-machine interface, supports touch screen and multi-functional button operation
  • Battery cold start and mains power start available
High intelligence
  • Powerful network monitoring management with multi-platform communications: standard RS232/RS485/dry contacts, optional SNMP communication interfaces are used for monitoring UPS running status
  • Advanced intelligent battery management (ABM)
  • Uses integrated design of rectifier/charger, sets up parameters on interface according to configured battery capacity and automatically adjusts the charging current by software. Able to set the time of battery self-test and charge/discharge interval according to the grid security situation to extend the lifetime of the battery
