SVS, Air Cooled, 50 KVA
Three-phase air-cooled SVS, 50 KVA. Fast correction, 97%+ efficiency, no waveform distortion. Ideal for offices and light industrial loads.
Product Description
This 50 KVA three phase stabilizer handles both balanced and unbalanced supply and load. Output runs at 330V/400V/415V, adjustable, with efficiency above 97% and correction rates better than 36V/second in the air-cooled configuration. It also tolerates frequency variation between 47Hz and 53Hz.
The typical fit is commercial buildings, hospitals, office complexes and light to medium industrial setups, essentially anywhere HVAC systems, elevators, or networked equipment run on three phase power. Plug-in glass-epoxy control cards make servicing straightforward, so a card swap doesn’t mean pulling the whole unit offline for long.
Because it’s air-cooled, the footprint stays smaller than an oil-cooled equivalent at the same capacity, which matters in facilities where floor space is tight. It’s a reasonable middle ground for sites that need three-phase correction but don’t have the heavy, continuous industrial load that would justify oil cooling.
Automatic Correction
Corrects voltage automatically and continuously, keeping supply stable at all times.
Motor Protection
Ensures induction motors operate at high efficiency by supplying constant voltage.
Equipment Protection
Protects costly equipment from High/Low voltage menace, cutting down maintenance costs.
Reduced Production Losses
Minimizes production losses and improves overall plant efficiency.
Increased Productivity
Stable voltage supply leads to increased productivity across operations.
Tax Benefit
Eligible for 100% depreciation as per Income Tax Act.
Lower MDI
Reduces Maximum Demand Indicator (MDI) and saves power.
Electricity Savings
Reduces electricity bills by up to approximately 15%, depending on input variation and working hours.
Diesel Savings
Saves on diesel cost, as generators need not run at High/Low input voltage.
Fast ROI
Average payback period of approximately 18 months owing to high energy-saving capability.
Recommended Applications
- Information Technology & Call Centers
- Computer and Micro-Processor Controlled Equipment
- Scientific, Medical, Agricultural & Educational Research Instruments
- Offset Printing Presses, Color Scanners, Phototypesetters & Photographic Equipment
- Medical Equipment — X-Ray Machines, ECG Machines/Monitors, MRI, CT Scans

Not Recommended For
- Small single-appliance loads like a single fan or light, where a plug-in voltage protector is more economical
- Applications requiring instantaneous (zero-time) correction, since servo stabilizers correct voltage gradually via a motorized mechanism
- Extremely space or weight-constrained installations, as servo units are bulkier than static/AVR types
- Environments with frequent, rapid voltage fluctuations occurring within milliseconds, where a static (electronic) stabilizer responds faster
- Portable or frequently relocated setups, since servo stabilizers are typically fixed installations
