DESIGN CONSIDERATIONS
Parallel connection of multiple units
Two units parallel operation is verified, please contact Delta if more than two units need to be paralleled.
While parallelling multiple units, the impedance of the cables from unit to junction point of each unit should be
within ±5% of each other.
Figure 17: suggested parallel connections
EMC
The converter has the internal EMI filters and meet the EMC standards EN12895 30-1000MHz
34-45dBuV/m.The test result is showed as below
Conditions: Vin=48V, Io=24A, 10m measure distance

Fuse replacement
For the versions with the intergratted the fuse holder, when the fuse needs to be replaced, it can be taked down
in an anticlockwise direction by slotted type screwdrivers .
