this has a dc requirement for loads greater than 400 Watts, but not
less like most avionics boxes. UNless I missed something.
Seems like something is missing to me.
There are difficulties with controlling DC conducted emissions, which is
why IEC/EN 610003-2 and -12 don't even try. Instead, they put strict
limits on even harmonic emissions, which can only be met if the DC
component is also very low.
DO-160 may adopt the same method of controlling DC for lower power
products.
