Product details
Reactive Power Compensator SMone SM-SVG-20-0.4-4L-W
The active reactive power compensator SM-SVG-20-0.4-4L-W is a three-phase device designed for reactive power compensation in 0.4 kV installations. It provides precise power factor regulation (>98%) and features high efficiency (>97%). The device operates in a 3L+N+PE configuration and is equipped with an intuitive touch screen.
Key features of the SM-SVG-20-0.4-4L-W:
- Rated compensation capacity: 20 kVAr (single-unit or capacitor-based).
- Wide operating voltage range: 320-460 V AC.
- Fast response time: under 10 ms.
- Advanced features: compensation to a set cos(φ) and balancing of three-phase asymmetry.
- Parallel operation capability: up to 8 units for increased capacity.
- Built-in 4.3″ touch screen and compatibility with an external 7″ HMI panel.
Who is this a good choice for?
The SM-SVG-20-0.4-4L-W is an ideal solution for industrial and commercial facilities where reactive power demand varies and improving the power factor is necessary.
