KEMOT PROavr-100k 100 kVA Three-Phase Automatic Voltage Stabilizer, Servo Motor, 280-430V Input, 380V Output, LCD, Black

Delivering a robust 100 kVA (100,000 VA) capacity, the KEMOT PROavr-100k three-phase automatic voltage stabilizer ensures stable 380V output for industrial and commercial equipment, even when input voltage fluctuates between 280V and 430V phase-to-phase. Its servo motor control technology continuously adjusts voltage with an efficiency of at least 95% and a response time under one second, protecting sensitive machinery from power anomalies.

Overview

The KEMOT PROavr-100k is engineered for demanding three-phase power environments. It accepts a wide input range of 160V–250V phase-to-neutral (280V–430V phase-to-phase) and delivers a regulated output of 220V phase-to-neutral (380V phase-to-phase) with ±3% accuracy. This makes it ideal for factories, workshops, data centers, and any facility where voltage stability is critical for operational continuity.

What stands out

• High capacity: 100 kVA supports heavy loads and multiple devices simultaneously.
• Servo motor stabilization: precise voltage correction with minimal waveform distortion.
• Wide input range: handles severe under-voltage and over-voltage conditions.
• Comprehensive protection: safeguards against overload, overvoltage, undervoltage, short circuit, overheating, and phase loss.
• Clear LCD display: real-time monitoring of input/output voltage and status.
• Robust cooling: fan-cooled design with Class F insulation for reliable operation up to 45°C.
