ELECTRICAL CHARACTERISTICS
Electrical characteristics apply over the full operating range of input voltage, output load (resistive) and baseplate temperature,
unless otherwise specified. All temperatures refer to the operating temperature at the center of the baseplate.

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,
contact Vicor applications engineering at 800-927-9474.
MODULE MECHANICAL SPECIFICATIONS
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".
For long pin configuration add “L” to the end of the
part number.
See page 7 for pin dimensions.
