Three Phase Servo Stabilizer - PRO-S Series | 10KVA

The PRO-S 10KVA is a three-phase servo voltage stabilizer built to ensure stable and uninterrupted power delivery for electrical systems exposed to inconsistent mains supply. As an automatic servo voltage stabilizer, it accepts an input range of 280V – 480V across all three phases and corrects the output to a steady 3×400V held within ±1–1.5% accuracy, keeping connected equipment protected from voltage fluctuations, surges, dips, and phase disturbances around the clock.

Built for continuous operation, this electrical stabilizer handles up to 14.43A per phase at 10KVA with an efficiency of up to 98%. Class H insulation combined with a low-loss thermal design keeps internal temperatures stable across extended duty cycles. A digital LCD display presents live input and output voltage readings across all three phases simultaneously, while eight automated protection layers — covering overvoltage, undervoltage, overload, short circuit, overtemperature, phase sequence fault, phase failure, and internal bypass — respond instantly without operator input. A 6-second safe-start delay activates at every power-on cycle to prevent inrush stress on the connected load.

Well suited for light industrial machinery, commercial kitchens, water pumping systems, and multi-zone air conditioning installations, the PRO-S 10KVA servo stabilizer is floor-standing on industrial castors for easy on-site positioning. Connecting via screw-type terminals and operating in ambient temperatures up to 50°C, this servo motor stabilizer carries CE, cULus, and TÜV Austria certifications — a dependable three-phase electrical stabilizer available across Egypt for commercial and industrial applications.
