4.3 Product features
• Dynamic compensation of harmonics currents
• Inductive and capacitive reactive power components
• Simultaneous harmonic compensation,
power factor correction and balancing of asymmetrical
loads
• Automatic resonance detection
• Compensation of the neutral conductor current in the
4-lead connection
• Simultaneous compensation of the 2nd - 50th harmonic
with a fixed compensation frequency;
• Power factor correction: fast (ms reaction time), exact
power factor correction (-1.0<cos
φ
<1.0)
• Compensation strategy can be modified during ongoing
operation
• Freely configurable compensation rate for each individual
harmonic (even and odd numbered)
• Modular system for easy adaptation to modified network
and load conditions
• Automatic mains frequency detection
• Suitable for installation sites with poor mains power
quality: (broad input voltage and frequency range)
228 V - 456 V
• Low-feedback and low-loss operation
• High clock frequency
• Standby operation in dependence on the voltage
distortion (THD) and/or the imbalance
• Automatic restart after voltage loss
• User friendly user interface: Automatic error messages,
fault messages and operating log
