Datasheet: MV380 Series

520 WATT DC-DC CONVERTER
MODEL MV380-26
DATA SHEET
Distributed Power in Telecom, Industrial Control, Wireless, & Computer Applications
INPUT: 380VDC • OUTPUT: 26VDC @ 20.0A • 520 WATTS
Size: 2.4 x 4.6 x 0.5 inches
DESCRIPTION
MEGAVERTER DC-DC converters are high density, feature rich modules packaged in the
industry standard “full brick” size (2.4 x 4.6 x 0.5 inches) for circuit board mounting. They are
used where large blocks of DC power are required. The MV380-26 is designed for use with a
PFC front end and provides up to 520 Watts of low noise, 26Vdc power from a universal ac
line.
