ADEL MR220 Decoupling Module Features

The decoupling module is a dual input diode with 2 inputs and one output, suitable for various applications such as to produce redundant applications to decouple power sources from each other as well as from the loads e.g. separation of sensitive loads from the power bus, design buffered branches, block reverse power, etc.

ADEL MR220 Decoupling Module Input

In Current (Dual Input Mode;1+1Redundancy) 2 x 12.5 A max
Input Current (Single) 1 x 25 A max
Input 1 10 – 60 Vdc, 0 – 25 A
Input 2 10 – 60 Vdc, 0 – 25 A
Peak Current 200 A for max. 10 ms
Reverse Current 25 mA max. per diode

When both inputs are used “Dual Input Mode” the output current results as the sum of the two inputs, max 25A. If used with only one input “Single Input Mode”, both positive input terminals can be linked.
