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. 

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:  

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:
