Dump load controller

Dump load controller

Orbital dump load controller (OrbiDLC) is a highly efficient 3-phase to DC converter specially designed for bypassing overproduction and peaks from wind turbine generators to external dump load(s).

The throughput can be precisely controlled through either analog or digital interfaces. Designed for real time operations with latency under 0.5 ms and up to 1.000 set points per seconds.

High frequency PWM IGBT switching provides high efficient and no audible switching noise. Optional inductors can be directly connected to the DLC in order to reduce harmonic current distortions.
