Q1: With a ±40% input range, what exact voltage range does this cover for a standard 380V system?
For a nominal 380V system, a ±40% input range is exceptionally wide. It means the stabilizer can accept an input voltage as low as 228V (380V - 40%) and as high as 532V (380V + 40%). This extraordinary range allows it to function in locations with severe grid problems, near heavy machinery causing sags, or in rural areas with long, unstable power lines, where other stabilizers would fail to operate or trigger protections.
Q2: Can this single 200 kVA unit stabilize power for an entire small commercial building or industrial plant?
Yes, a 200 kVA unit is often used as a centralized, facility-wide solution for small to medium commercial buildings (e.g., offices, hospitals, schools) or industrial plants. It would be installed at the main service entrance or on a critical feeder, conditioning the power for all downstream equipment. However, a professional load analysis is essential to confirm that the building's peak and continuous demand do not exceed the unit's capacity and to plan for future expansion.
Q3: How does the high efficiency (>95%) translate to measurable cost savings?
The efficiency rating indicates how much of the input power is delivered to the load versus lost as heat. For a 200 kVA unit running continuously at full load, even a few percentage points of loss represent significant energy. At >95% efficiency, losses are kept below 10 kVA. Over a year of continuous operation, this can result in tens of thousands of kilowatt-hours (kWh) in saved energy compared to a less efficient unit, directly lowering electricity bills and reducing cooling requirements for the equipment room.
