Buffer energy supplied from a DC-UPS or buffer module is not wasted in “power branches”.
Please note:
Set output voltage of the power supply to a level that the buffer unit or DC-UPS will not start unexpected. Take the
voltage drop of the YR2.DIODE into account.

NCLOSURE
When the redundancy module is installed in a tightly sealed enclosure, the temperature inside the enclosure will be
higher than outside. The inside temperature defines the ambient temperature for the redundancy module.
higher than outside. The inside temperature defines the ambient temperature for the redundancy module.
Results from such an installation:

Load:
24V, 16A; (=80%) load is placed outside the box
Input:
24Vdc
Temperature inside enclosure:
57.8°C (in the middle of the right side of the power supply with a distance of 2cm)
Temperature outside enclosure: 24.6°C
Temperature rise:
Temperature rise:
