Heavy-Duty Power Supply – Ideal for Factories and Data Centers

A 1500kVA alternator provides approximately 1200 kW of real power—an impressive figure for heavy industrial applications where high energy demand and uninterrupted supply are critical.

In industrial parks, metallurgical plants, automated production lines, or data centers, the demand for continuous and stable power is enormous. Utilizing a 1500kVA alternator offers:

  • Uninterrupted electricity for automated systems

  • Reliable operation for heavy machinery

  • Reduced losses from power outages

  • Secure data system maintenance without shutdowns

Mecc Alte alternators are designed for continuous operation (continuous power rating) under harsh conditions, ensuring stable performance in high temperatures, humid environments, or corrosive atmospheres like chemical factories.


High Voltage Stability – Protecting Sensitive Electrical Systems

One of the standout advantages of the Mecc Alte 1500kVA alternator is its ability to maintain stable voltage and frequency even under sudden load changes.

Equipped with an integrated AVR (Automatic Voltage Regulator) system, this alternator maintains voltage deviation within ±1%, which is crucial for:

  • PLC-based control systems

  • IT equipment, servers, and control cabinets

  • High-precision machinery

Its low Total Harmonic Distortion (THD) also increases the lifespan of downstream electrical equipment and minimizes the risk of surges or electrical fires.

European Design – Durable and Performance-Oriented

Mecc Alte is one of the few European brands that manufactures 100% in Italy, maintaining strict quality control from stator winding and rotor balancing to insulation coating. The 1500kVA alternator offers several key features:

  • Class H insulation materials – withstands temperatures up to 180°C

  • SKF industrial-grade bearings – ensures mechanical durability

  • Compact design – easy integration into generator sets

The epoxy coating adds protection against salty air, humidity, and dust, enabling a lifespan of 20,000 to 30,000 hours, which equates to over 10 years of operation with proper maintenance.


Smart AVR and Comprehensive Protection System

The AVR system in the Mecc Alte 1500kVA alternator not only ensures precise voltage control but also includes robust safety features:

  • Over-voltage and under-voltage protection

  • Phase loss and frequency fault disconnection

  • Soft start function for stable load pickup

  • Modbus communication compatibility for remote monitoring and SCADA systems

The alternator can also be equipped with thermal sensors, humidity detectors, and vibration monitoring systems for early fault detection—helping technicians plan proactive maintenance.
