New Output Studs
New, more robust output studs (with a 3:1 safety margin @ 45 in. lbs.) were installed in
ConverterPACs, the slide-in assemblies used in the MegaPAC Family. These new outputs
studs are 1/8" longer to allow for multiple lugs. They are fully compatible with the
original flanged nut ConverterPACs for use in parallel arrays.
Other advantages include:
n Inner nut (that might become loose) replaced by a brass insert
n Stronger connection to the PCB
n Improved conductivity (less voltage drop and heating)
n Both the stud and panel are less likely to break due to over-torqueing
Shown below are the original and re-designed studs.
