Power control for vehicles, machines and marine applications

Danfoss editron electric drivetrains are specially designed for controlling the flow of hybrid and electric power in vehicle, machine and marine applications. Converters are specifically developed for electric or hybrid drive trains in mobile work machines, buses, harbor cranes or marine vessels. 

Converters with power range 100-1,000 kW

EC-C converter is available as two variants suitable for two different system voltage levels as EC-C1200-450 and as EC-C1700B-420. The EC-C1200-450 is meant for up to 850VDC/500VAC voltage levels and the EC-C1700B-420 is meant for up to 1200VDC/690VAC voltage levels. The EC-C converters are built with components that can handle double the number of load cycles. Which is compared to components used in standard industrial inverters. The standard lifespan of EC-C products is up to 20 years. The high-performance vector control of Danfoss EC-C drives the motors accurately and smoothly. It can control induction motors (IM) and permanent magnet (PM) motors.

Additionally, Danfoss reluctance-assisted permanent magnet (SRPM) motors with or without sensors. The EC-C can be selected with different software options. This allows EC-C1200-450 to work as active front end, microgrid, motor control (inverter) and as a DC-to-DC converter when combined with EC-LTS1200-410. The EC-C1700B-420 similarly supports active front end, microgrid and motor control (inverter) but not DC-to-DC converter
