24 & 48 VDC alternators
from 60A to 800A with digital AVR
24 & 48 VDC direct current alternators up to 800A for battery charging, lighting towers and telecoms
Discover Sincro's complete range of highly efficient 24/48 VDC alternators, engineered specifically for direct-current gen-sets and extra-low voltage (ELV) systems. Manufactured in Italy, this diverse lineup includes 28 different models capable of delivering reliable energy from 60A up to 800A.
Designed as a complete turnkey solution for original equipment manufacturers (OEMs), these alternators eliminate the need for external rectifiers or inverters.
Key Technical Highlights
Designed for maximum performance and ease of assembly, these units boast several advanced engineering features:
-
Compact design: An integrated AC/DC rectifier bridge allows for a smaller footprint and simpler mounting on gen-sets.
-
Flexible operation: Features a wound-type rotor (available in 2 or 4 poles) that supports a large operating speed range.
-
High efficiency: Engineered to maximize power output while minimizing waste.
Advanced Voltage Control
Consistent power delivery is guaranteed through sophisticated, built-in voltage management:
-
Delivers reliable DC constant voltage.
-
Maintains high stability even when operating across a wide range of speeds.
-
Equipped with a precise Digital AVR (Automatic Voltage Regulator).
-
Offers an adjustable voltage set-point controlled via a trimmer, external potentiometer, or an outer controller.
-
Ensures low ripple, making it safe for sensitive electronic equipment.
Bottom-Line Cost Savings
Investing in our integrated technology translates directly to reduced operational and manufacturing expenses:
-
Fewer components needed: Eliminates the need for external inverters or stabilizers.
-
Lower running costs: Achieves reduced fuel consumption during operation.
-
Reduced downtime: Built to minimize the need for ongoing maintenance.
-
Streamlined manufacturing: Optimized assembling costs for OEMs due to the all-in-one design.
