Description
Compact Activar/Equalizer – Compact Reactive Power Compensation Unit
The Compact Activar/Equalizer are static/dynamic VAR compensation systems for transient-free power factor correction and dynamic load compensation.
Traditional power quality systems are often larger, complex and expensive. Our compact systems emerge in response to these challenges for industrial and commercial sectors with limited space. With a footprint of only 120(H) x 102(W) x 76(D) cm, our system’s are the most efficient design offered by Elspec.
Key Features
- Real-time power factor correction
- High resolution compensation
- Compact & efficient design
- Alternative to conventional, larger compensation systems
- Designed for industrial & commercial applications
As with all Elspec’s power quality solutions, our compact systems are compensating the voltage, harmonics, voltage flickering & fluctuations, at zero-crossing. This makes them the fastest Power Factor correction systems.
