DESCRIPTION:
The MEGAVERTER® MV24-28-600S dc/dc converter is a high density, feature
rich module packaged in the industry standard “full brick” size (2.4 x 4.59 x
0.5 inches) for circuit board mounting. It is designed for use in a 24/28 Vdc
(18-36Vdc) input applications where large blocks of DC power are required.
The MV24-28-600S utilizes an insulated metal substrate and is therefore well
suited for the most rigorous requirements of COTS and thermally challenging
industrial applications.
