Product overview
The Voltage Sag Mitigation Solution for Sensitive Industries is a specialized device designed to protect sensitive loads from power quality disturbances, particularly voltage sags.
In simple terms, when sensitive equipment is connected to the AC power grid, disturbances such as voltage dips, sudden fluctuations, or harmonic distortions can significantly affect performance, stability, and even cause operational interruptions.
To minimize these impacts, a Dynamic Voltage Restorer (DVR) is connected in series with the three-phase circuit. During grid faults or disturbances, the DVR injects compensating voltage into the load side, ensuring stable and reliable voltage supply to sensitive equipment.
This solution is particularly critical in industries where high reliability and stability are essential, such as:
Semiconductor and electronics manufacturing
Pharmaceutical and biotechnology plants
Precision equipment and data centers
Petrochemical and chemical processing facilities
By mitigating voltage sags and harmonics, the system ensures consistent power quality, protecting sensitive industrial processes and reducing production downtime.

Model Description
RWDVR 04–300 H F N–040 C
C / A: Supercapacitor / Electrolytic capacitor
Protection time (s): e.g., 040 = 0.4 s
N: Three-phase four-wire (no N = three-phase three-wire)
F / B: Front access / Rear access
H / L: Top access / Bottom access
Rated protection capacity (kVA): e.g., 300 = 300 kVA
Voltage class (kV):
02 = 208 V
04 = 400 V
06 = 600 V
6 = 6 kV
10 = 10 kV
DVR: Dynamic Voltage Restorer
Brand: Rockwill Energy
Notes:
Protection time is a three-digit scientific notation, unit in seconds (s). For example, 363 = 3.6 × 10³ s (≈1 hour), 040 = 0.4 s.
Rated protection capacity range: 30–5000 kVA (see technical parameters table).
