No-Break  UPS

HYDRA series no-break ups have unique features that offer unique power availability to the load.  

They use continuously two power sources to support the load. The inverter and the power grid. Both sources are continuously  synchronized to support the load. The inverter monitors and corrects the power grid when needed, up to well defined and pre-programmed limits.  When the power grid is out of the programmed limits, it is rejected. Therefore the load is supported by the inverter only for short periods of time, or during power grid outages.

The charging of the internal batteries is done actively by a three stage charger. 

The inverter follows the frequency of the external AC power up to programmable limits before rejecting it, using a digital phased lock loop. In case of unstable grids or diesel generators, the user may widen the acceptable limits accordingly. 

HYDRA ups  deliver clean AC power to sensitive loads, like computers, scientific instruments, communication equipment.

They are designed to provide all the necessary functions and utilities which offer a fully automated user friendly and care free operation.

  Features:

  • Micro-processor based design with alphanumeric led display for full monitoring and control of the Hydra ups.
  • Automated and synchronized switch over between the grid and the inverter by continuous analysis of the AC voltage quality and frequency.
  • Monitoring of the actual battery voltage and of the actual expected autonomy duration in minutes.
  • Monitoring and display of the actual load in % of the nominal value.
  • High efficiency, high power inverter delivers true RMS stabilized, full sinewave AC power.
  • Monitoring of the inverter true RMS AC output voltage, of the percentage of the load, of the battery voltage, of the power module and of the power transformer temperatures.
  • Visual and selectable audible early warning alarms signaling undesirable trends or situations.
  • Error situation signaling and intelligent automated timed retrials, automatically adapted to any specific situation.
  • Unlimited autonomy on demand for all models.
  • Standard backup time for nominal load minimum 15 minutes
  • Two years limited guarantee
