Main Features
This new product is significantly more economical and efficient than its competitors, and the DC-Link capacitor fault diagnostics algorithm can reduce maintenance costs and predict life expectancy.
01
Superior performance
and efficiency
- Total Harmonic Distortion (THD) and order-specific harmonic
compensation (selectable from 2nd to 50th odd orders)
- Displacement Power Factor (DPF) correction and Power Factor
(PF) correction
- Real-time mitigation of harmonic currents through IGBT
02
Safety improvement with built-in
Protection Circuit
- Short circuit, over voltage, overcurrent, phase sequence failure
and current reverse sequence protection
- Application of DC Link capacitor fault diagnosis algorithm
- No resonance with the system
- Auto stop and reset button
03
Modular design considering
expandability
- Modular structure with improved system reliability through slim
design
- Implement space optimization with rack-mounted type and wallmounted
type
- System configuration optimized for 3-phase power
04
Intelligent FFT
- Unique intelligent FFT algorithm
- System impedance automatic calculation → resonance prevented
- Maintaining high system reliability
05
Graphical user interface
- 7 inch central HMI
- Displays voltage, current, frequency, before and after THDi,
apparent/active/reactive power, etc.
- User-centered interface configuration
