Three-phase voltage stabilizer Volt Polska AVR PRO 15000 3% SERVO 3-F

The Three-phase voltage stabilizer Volt Polska AVR PRO 15000 3% SERVO 3-F is a servo-controlled automatic voltage regulator designed to provide a stable three-phase output for industrial and commercial electrical installations. With a rated capacity of 15 kVA and an output regulation of ±3%, the device compensates for voltage fluctuations and delivers a consistent supply suitable for motors, pumps, HVAC systems and sensitive electronic equipment in factories, workshops and small data centers.

Advantages

The stabilizer uses servo drive regulation to maintain output voltage within a tight 3% range, offering reliable protection against undervoltage and overvoltage conditions. Its three-phase design ensures balanced correction across all phases, reducing the risk of phase-to-phase imbalances and equipment stress. Built for continuous operation in commercial environments, the unit supports a variety of loads including inductive and resistive equipment while helping to extend service life and reduce downtime.

Suitable for

• Industrial motors and pumps
• Heating, ventilation and air conditioning (HVAC) systems
• Workshop machinery and production lines
• Small data centers and server rooms with three-phase supply
• Sensitive electronics and control systems

Key specifications

• Rated capacity: 15 kVA three-phase
• Voltage regulation accuracy: ±3%
• Control type: servo motor driven automatic voltage regulation
• Phase configuration: three-phase input and output
• Suitable load types: inductive and resistive loads
• Continuous operation capability for commercial/industrial environments

How to use

Install the stabilizer in a dry, well-ventilated location close to the main distribution panel and connect to the three-phase supply following local electrical codes. Ensure correct phase sequencing and proper grounding before energizing. After connection, switch the unit on and monitor the front indicators or meters to verify stable output voltage. Periodic inspection of mounting, connections and ventilation is recommended to maintain performance.

Usage recommendations

For optimal performance, match the connected load to the stabilizer’s 15 kVA rating, avoid sustained overloads, and allow adequate clearance for ventilation. Regular preventive maintenance, including visual inspection of servo components and tightening of electrical connections, will help ensure long-term reliability.
