Baseplate
Slotted (Style 1)
Slotted baseplate (style 1) requires no designator.
For threaded baseplate add a "2" to the end of the
part number. For thru-hole add a "3".
Pin Style
Short (Style 1)
For long pin configuration add “L” to the end of the
part number.
See page 7 for pin dimensions.
MODULE MECHANICAL SPECIFICATIONS
Note: For important information relative to applications where the converter modules are subject to continuous dynamic loading,
