YRM2.DIODE

Y-Series

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 YRM2.DIODE into account.

Note: Use separate mains systems for each power supply whenever it is possible

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.

Results from such an installation:

Power supply is placed in the middle of the box, no other heat producer inside the box

Enclosure:

Rittal Typ IP66 Box PK 9516 100, plastic, 110x180x165mm

Load:

24V, 16A; (=80%) load is placed outside the box

Input:

24Vdc

Temperature inside enclosure:

58.8°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:

34.2K
