The PRO-S 6KVA is a three-phase servo voltage stabilizer built to deliver dependable voltage regulation for small-to-medium installations where mains supply quality cannot be guaranteed. This automatic servo voltage stabilizer spans an input range of 280V – 480V, actively corrects incoming voltage across all three phases, and holds the output at 3×400V within ±1–1.5% accuracy — providing connected equipment with a clean and stable power feed regardless of grid conditions.


Handling up to 8.66A per phase, this electrical stabilizer is designed for efficient continuous operation at up to 98% efficiency. Class H insulation and a low-loss thermal assembly maintain safe internal temperatures throughout extended run times without the need for active cooling. A digital LCD display shows live input and output voltage across all three phases, while eight automated protection functions — overvoltage, undervoltage, overload, short circuit, overtemperature, phase sequence fault, phase failure, and internal bypass — activate instantly when operating parameters are exceeded. A 6-second safe-start delay at every power-on cycle shields downstream equipment from inrush stress.


Compact and floor-standing on industrial castors, this servo stabilizer suits small workshops, retail outlets, telecom equipment rooms, and light commercial air conditioning systems. Connecting via screw-type terminals and rated for ambient temperatures up to 50°C, the PRO-S 6KVA servo voltage stabilizer carries CE, cULus, and TÜV Austria certifications — a fully compliant three-phase electrical stabilizer available across Egypt for commercial and light-industrial applications.
