CHARACTERISTICS
  • Technology True On-Line Double Conversion Technology provides perfect output voltage parameters, regardless of the input voltage and the load.
  • Rectifier IGBT the most advanced technology which provides very load THDi and high power factor.
  • Automatic bypass provides continuous load supply in critical conditions, such as overheating or inverter failure.
  • Maintenance bypass enables service handling without necessity of shutting off the load.
  • Communication:
    - RS232, RS485, MODBUS for UPS and load supervision and control,
    - DryContact alarm indicators; work with BMS system
    - SNMP integration with systems management network NMS.
  • Remote emergency power off (REPO) provides remote shutting off the load and UPS in the case of emergency.
  • Emergency power off (EPO) on UPS provides very quickly shutting off the load and UPS.
  • LCD control panel displays UPS and power parameters as well as hundreds of useful information.
  • Small dimensions requires small area for unit operation.
  • High efficiency (>96%) reduces heat dissipation and limits power consumption costs.
  • ECO-Mode gives possibility of significant cost reduction and in practice stops heat emission.

 

  • Automatic diagnostics and fully digital control (2x 32bit DSP) ensure that components and parameters are controlled without user interference.
  • High input power factor 0,99 reduces the value of current drawn from the mains.
  • The highest output power factor up to 1,0 allows load of versatile characteristics to be powered.
  • Wide input voltage range for normal mode ensures that batteries are used only if necessary – in fact, only when the input voltage is completely lost.
  • Wide input frequency range for normal mode gives possibility for seamless operation with different power sources – as mains or the generating set.
  • Simple maintenance microprocessor control and 24/7 operation mode means that unit does not require specialized handling.
  • Advanced battery management gives reliability of optimal charging and using batteries, elongates its lifetime and reduces operating costs.
  • Excellent voltage quality is provided by 3level IGBT inverter ad high frequency PWM technology, the output voltage has always stable parameters independent of input disturbances and the load characteristics.
  • Advanced software provides to customer full control of unit and load.
  • User configurable settings enable user to set nominal voltages, frequency, preferred operating modes.
  • Redundancy configurations:
    - parallel for capacity or redundancy
    - Hot Standby
