EH Series, Three Phase In-Single Phase Out 10/ 15/ 20 kVA

The Ultron EH Series is an online double-conversion 3p-1p UPS which provides reliable power protection for IT rooms, telecommunications, banking, medical facilities, and industry.
Supported with DSP based technology, it offers rapid computation capabilities that enhance system stability and provide precise voltage to load. The Ultron EH Series offers many superior features including N+X parallel redundancy and a built-in manual bypass switch to guarantee higher availability and reliability for protecting your critical loads.

Applications :


  • True online double-conversion technology to completely protect the critical load from problems occuring on the source side
  • DSP based technology to support rapid computation capability and a simplified control circuit for enhanced stability
  • Dual input design to allow different power supply sources for enhanced availability
  • Built-in manual bypass ensures continuous power to the load during maintenance
  • A wide input voltage range to reduce battery discharge probability and prolong battery life
  • ECO mode efficiency up to 96% to reduce operating cost
  • Small footprint to save space
  • Parallel expansion and N-X redundancy up to 4 units without requiring additional hardware
  • Additional internal charger and external charger box provide flexible capacity expansion
  • Remote and local emergency power-off functions (EPO) to promptly manage the UPS when emergencies occur
  • Multi-connectivity interface to support remote UPS monitoring and management
  • Advanced management software to provide event alert management, remote shutdown, event log tracking and analysis
  • Reliable battery management for better battery protection
