Three-Phase Voltage Regulators (Stabilizers)

Where are three-phase voltage regulators used?

Three-phase voltage regulators (stabilizers) bring mains voltage varying between 275 and 430 V to a stable 380 V output. Their main applications include factories, production lines, CNC and plastic injection molding machines, elevators, cold storage facilities, hotels, hospitals, data centers and agricultural irrigation systems.

Independent regulation of each phase

Voltage differences between phases are common in industrial zones. Because Artı three-phase regulators correct each phase with a separate servo mechanism, they deliver equal and stable voltage on all three phases, even on unbalanced networks.

Choosing the power rating

• 6–15 kVA (load approx. 3–7.5 kW): small workshops, a single CNC machine, elevators, cold rooms
• 22.5–45 kVA (load approx. 11–22.5 kW): medium-sized workshops, hotels, clinics, agricultural irrigation
• 60–150 kVA (load approx. 30–75 kW): factories, production lines, data centers, shopping malls

The ranges follow the rule of choosing a regulator rated at twice the total load running at the same time.
