• Manufacturer Part Number: smflhp
• Description: Dc/dc Converters 28 Volt Input
• Manufacturer: Interpoint Corp.

Electrical Characteristics:
Notes
1. Up to 70% of the total output power (current) is available from either output
2. Unit will shut down above approximately 45V but will be undamaged and
provided the opposite output is carrying 30% of the power (current) in use.
will restart when voltage drops into normal range.
