Heat dissipation
The heat generated by the SD700 depends on the carrier frequency (Hz), the grid frequency and the load.
It could be estimated by the following equation. Rated power condition is the worst case.

(*)The air velocity, which passes through the gratings, varies between 5 and 6 m/s depending on the blocking of the
gratings.
