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.

MODULE OUTPUT VOLTAGE RELATED SPECIFICATIONS

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.

Note: 300 Vin models do not have overvoltage turn-off.
