Ultrafast Correction Speed
Solid-state switching operating at frequencies up to 20kHz allows regulation within 20ms to 30ms, correcting line sags and spikes before downstream sensitive electronics detect disturbance.
Static Voltage Stabilizer
High-Speed Solid-State Voltage Regulation (10kVA to 500kVA) Engineered with IGBT PWM Switching Technology for Flawless Power Continuity
Engineering Precision
Next-Generation Electronic Voltage Stabilization
An industrial Static Voltage Stabilizer (SVS)—also known as a static voltage regulator—represents the evolution of precision power regulation, delivering the stabilizing performance of traditional servo stabilizers completely free of mechanical moving parts. While conventional servo units adjust output voltage through motor-driven carbon brushes on variable autotransformers (which causes mechanical lag and periodic wear), a static voltage regulator performs voltage correction purely through high-frequency solid-state power electronic circuitry.
Manufactured using advanced Insulated Gate Bipolar Transistor (IGBT) architecture and high-frequency Pulse Width Modulation (PWM) control, Prima Static Voltage Stabilizers accomplish direct AC-to-AC switching without requiring lossy AC-DC-AC double conversion stages. This ensures seamless, harmonic-distortion-free pure sine wave output with response speeds up to 500 times faster than electromechanical alternatives—correcting severe utility voltage fluctuations in as little as 20 to 30 milliseconds.
Engineered at our 5,500 m² plant in Santej, Ahmedabad, every unit is assembled with high-efficiency buck-boost isolation transformers, built-in EMI/RFI filtration, and intelligent microprocessor controls to protect sensitive CNC lines, automated robotics, data centers, and advanced medical diagnostics from transient voltage sags, surges, and electrical noise.
Zero Moving Parts & Maintenance
Eliminating servo motors, carbon brushes, relays, and shafts removes mechanical wear-and-tear, yielding high MTBF, silent operation, and near-zero lifecycle service costs.
Microsecond Overcurrent Cutoff
High-speed DSP sensing continuously monitors output short circuits and instantaneous overload currents, isolating the IGBT modules within microseconds to safeguard downstream machinery.
Integrated EMI & RFI Filtering
Standard integrated electromagnetic and radio-frequency filters eliminate supply harmonic injection and shield industrial loads from upstream electrical transient spikes.
Compact & Lightweight Profile
Optimized high-frequency buck-boost magnetics deliver a physical footprint up to 40% smaller and significantly lighter than oil-cooled or servo-motor autotransformer regulators.
Independent Phase Balancing
Three-phase models offer independent sensing and voltage correction across individual phases, maintaining tight ±1% output symmetry even under 100% phase-unbalanced loads.
