APPLICATIONVOGI
Nordic offshore wind farms
Equinor wind farms in Norway use DO820 to drive the variable pitch system relays, which can withstand -30°C low temperature and salt spray corrosion.
North American smart buildings
In the HVAC system of Hudson Yards in New York, DO820 controls the start and stop of 2000+ wind turbines, increasing energy efficiency by 15%
