Three Phase Servo Stabilizer - PRO-S Series | 6KVA

The PRO-S 6KVA Three Phase servo voltage stabilizer delivers dependable voltage regulation for small-to-medium three-phase installations where mains supply quality cannot be guaranteed. Spanning an input range of 280V – 480V, it 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 at 6KVA, the unit is designed for efficient continuous operation with an efficiency rating of up to 98%. Class H insulation and a low-loss thermal assembly maintain safe internal temperatures throughout extended run times without the need for active cooling. A smart digital LCD display shows live input and output voltage readings 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.

The PRO-S 6KVA Three Phase is a practical solution for small workshops, retail outlets, telecom equipment rooms, and light commercial air conditioning systems. Compact and floor-standing on industrial castors, it connects via screw-type terminals and performs reliably in ambient temperatures up to 50°C. CE, cULus, and TÜV Austria certifications make it a fully compliant choice for three-phase power conditioning across a wide range of commercial and light-industrial applications.
