!!! CAUTION !!! : the new MOSFETs are not compatible with the old type. The new MOSFETs must only be used
with the new pc-boards DCDRxx. The new parts must not be mixed with the old parts, under no circumstances !
Especially at the machines with double power units (V40 and V50) it must be ensured, that both power units are
equipped completely with only one version.
old driver IC: JC429CPA
DCDR2x with new
driver IC: TC4429
