This type of product is controlled by an electronic voltage regulator and complies with generally accepted standards CEI2/3, EN60034-1, IEC34-1, VDE0530, etc. All electronic components in the new generation synchronous generators have been improved or developed from scratch, which has contributed to an increase in the degree of performance. At the same time, each new component of the device is interconnected with versions of an earlier version, which, if desired, can be applied in parallel.
Characteristics of brushless synchronous generators Mecc Alte
- All products have improved ventilation capabilities.
- They are equipped with upgraded couplings for the convenience of connecting a motor or a DC converter.
- The housings are positioned in such a way that they allow easy insertion of cables and access to service openings.
- A slight deviation from the voltage sine wave is provided by the improved stator winding (performed in 2/3 steps).
- Automatic protection is able to ensure the safe operation of personnel in all operating modes of the device. The degree of protection is IP-21 or IP-23.
- The devices have Class H insulation.
- Overloads are allowed: 20 seconds – 300%; 2 minutes – 50%; 1 hour – 10%. Overloads are allowed once during 6 hours of continuous operation.
- The voltage is regulated by an electronic system.
The highest quality of products is confirmed by international-class safety certificates.
