ATENCO AVR Series | 1–2000 kVA

ATENCO AVR (Automatic Voltage Regulator) series delivers stable, reliable, and efficient power for residential, commercial, and industrial applications. Engineered with high experienced experts, these stabilizers combine advanced servo-motor control with robust transformer design, ensuring precise voltage regulation in even the harshest power environments.

Covering a wide power range from 1 kVA up to 2000 kVA, the ATENCO AVR series provides the ideal solution for sensitive equipment, production lines, IT infrastructure, and heavy industrial loads.

The ATENCO AVR series (ATN1 & ATN3) utilizes compensation transformer technology with automatic servo regulation, continuously adjusting to voltage fluctuations in real time.

• Single-phase ATN1 models: 1–200 kVA
• Three-phase ATN3 models: 10–2000 kVA

With wide input ranges (±20%), high efficiency (>95%), and fast response (<1s for 10% change), our stabilizers protect against over-voltage, under-voltage, and transient disturbances. Designed for long service life, ATENCO AVRs ensure reliable protection for critical loads where power stability is essential.
