V300B28E250BL2

Product Overview

The V300B28E250BL2 from Vicor Corporation is an isolated module DC-DC converter for board-mounted power systems. It accepts a 180 V to 375 V input and provides a single 28 V output at up to 8.93 A, with a rated power of 250 W. The converter includes 3 kV input-to-output isolation and is packaged in a 9-DIP through-hole module. Its 88.5% efficiency and -10°C to 100°C operating temperature range support commercial information technology equipment designs that require isolated board-level conversion.

Key Features

• Isolated module DC-DC converter with one 28 V output
• Input voltage range of 180 V to 375 V
• Output current rating of 8.93 A and 250 W power capability
• 3 kV isolation between input and output
• Overvoltage protection and undervoltage lockout features
• 88.5% efficiency
• Operating temperature range from -10°C to 100°C
• Through-hole 9-DIP module package measuring 2.28 in L x 2.20 in W x 0.50 in H (57.9 mm x 55.9 mm x 12.7 mm)

Applications

• Commercial information technology equipment requiring isolated 28 V power from a 180 V to 375 V input bus
• Through-hole board-level 250 W power conversion for commercial ITE equipment

Design & Procurement Notes

Design teams should verify that the system input remains within 180 V to 375 V and that the 28 V load does not exceed 8.93 A or 250 W. The 9-DIP through-hole module requires PCB hole placement, mechanical clearance, and 12.7 mm height allowance in the enclosure. The 3 kV isolation rating should be considered against input-to-output separation requirements, while OVP and UVLO functions can be incorporated into system protection planning. Because the specified operating range is -10°C to 100°C, thermal management and ambient conditions should be reviewed during board layout and enclosure design.
