Of nominal output voltage. For trimming below 90%
of nominal, a minimum load of 10% of maximum
rated power may be required.
Note: For important information relative to applications where the converter modules are subject to continuous dynamic loading,

MODULE MECHANICAL SPECIFICATIONS
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.
