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

The PRO-S 10KVA Three Phase servo voltage stabilizer ensures stable and uninterrupted power delivery for three-phase electrical systems exposed to inconsistent mains supply. 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, the unit 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 smart 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.

The PRO-S 10KVA Three Phase is well suited for light industrial machinery, commercial kitchens, water pumping systems, and multi-zone air conditioning installations. Floor-standing on industrial castors for easy on-site positioning, it connects via screw-type terminals and operates in ambient temperatures up to 50°C. CE, cULus, and TÜV Austria certifications confirm its compliance for commercial and industrial use.
