Notes:
1. Output voltage tolerance is measured at nominal input and 75% load.
2. Output ripple is measured at 20 MHz bandwidth using 0.1
µF
and 10
µF
capacitors connected in parallel as close to the power supply terminals
as possible.
3. These units will operate at no load without damage. For most appli-
cations however,
MPD
recommends that a minimum load always be
used. Contact the factory for more information.
4. Each unit includes an input fuse (250V/2A). Since this fuse is not field
replaceable, it is recommended that an external fuse of the same size
be used on the input of the power supply for protection.

Safety Ground:
The mounting holes marked “Use metal standoffs” should be
connected to the system earth ground via metal spacers or
a cable. The input side mounting hole marked “FG” provides
the safety earth ground for the unit. This connection should
be locked to prevent possible loosening. Connecting the
output side mounting hole improves EMI.
