Description:
It adopts the most advanced analog logic method to eliminate harmonic. Real-time detect the wave form of the non-line loads in the grid. Active harmonic filtering, power factor improvement all in one, excellent quality, with the characters of quick response, widely filtering, high efficiency filtering, wont affected by the parameter of the system and it is small in size.
Performance characteristic
Combination of F.F.T. method and Instantaneous Power theory available for choice
Combination of power factor correction function (both inductive and capacitive power)
Wide harmonic filtering range: 2nd~50th harmonic can be filtered
High efficiency: harmonic filtering rate: more than 95%
Quick response: Fast dynamic response speed. Response time is 10 ms
Imbalance rectification available: single-phase dynamic current injection to rectify imbalance of supply system
Free from resonance due to automatic resonance elimination
Free from overload due to automatic current-limit output
Concurrent Var compensation: Filtering and Var compensation available for choice
LCD is adopted for interface operation, which can live indicate voltage, current and harmonic. Log record is available
Complete protection includes over voltage, under voltage, over current, over heat, under voltage of control supply and so on
Parallel-connected operation available: 10 sets can be connected in parallel
Directly applicable for system below 430V, and applicable for system with voltage higher than 400V when transformer is added
Plug-and-play design and easy scheme selection, no need for detailed analysis on supply network
Work conditions:
Ambient temperature: -10℃~40℃
Temperature for storage: -40℃~65℃
Relative humidity: up to 99%
Altitude above sea: 2000 meters
Working principle
Real-time detect the load current, quick distinguish the harmonic current component and fundamental wave, input equal and opposite compensate current into the grid to realize instant filtering and power factor improvement.
The passive current provided by ZAPF could be advanced or hysteretic, in order to improve the grid power factor and realize power factor improvement.
