Merus Uninterrupted Power Quality (UPQ) is an innovative concept, combining the functionalities of a UPS and an active harmonic filter into a single robust solution. UPQ protects mission critical processes from supply interruptions and voltage sags while maintaining supply voltage quality by compensating harmonic currents and the reactive power fluctuations of non-linear loads.

Merus UPQ provides complete protection through two operation modes
Power Quality Mode

In secured supply conditions, it operates in power quality mode, performing active filtering of harmonic distortion

Power Protection Mode

When it detects a voltage sag or power outage in the supply network, it shifts to power protection mode to protect against critical loads. UPQ is available from low up to medium voltage levels. "This guarantees maximum system availability and reliability. "

Benefits of Uninterrupted Power Quality
  • Comprehensive Protection With a Single Robust Solution
  • Enabling Interruption-Free Business Processes With a Dynamic Real Time Response
  • Entire facility protection with flexibility of connecting merus UPQ at any voltage level
  • Low loss solution which simultaneouslu extends the lifespan of facility by
  • Actively filtering harmonic distortions
  • Modern monitoring and reporting functionality
  • DVR is the most economical solution for mitigating upstream voltage disturbances in the distribution system.
  • DVR can be considered as a variable or controllable voltage source (VDV R) connected in series between the point of common coupling (PCC) (VS) and the load (VL).
  • DVR helps to regulate the load voltage profile by injecting appropriate voltage during the voltage quality events and allows control of real and reactive power exchange between the DVR and the distribution system.
  • The features such as sub-cycle protection, harmonic compensation and series conditioning adds more value to the DVR and increases the demand for it in the sectors with critical customer loads.

OSKαR®-Function Principle
  • OSKαR® is equipped with an online control which keeps the voltage continuously at the desired value: 400 V ordered, 400 V delivered!
  • As soon as OSKαR® detects a difference between the real voltage and the targed voltage it starts to adjust with a reaction time of 140 μs.
  • The voltage dip is fully corrected in less than half a cycle
  • 3 phase voltage dips of up to 30 % and overvoltages of up to 20 % are corrected

  • Realtime voltage correction (< 1 ms)
  • Circuit power remains nearly unchanged
  • Voltage dips down to 40 % of the nominal voltage can be corrected
  • Efficiency > 98 %
  • Extended operation is possible
  • Protection against overvoltages
  • No energy storage needed
  • Minimal space requirements
  • Low purchase and maintenance costs
