Mounting 

 
The EASY-DRIVER module can be used either as a desktop unit or as a rack-

mount device since the unit form factor is designed to be installed in a standard 19-inch 
cabinet.  

 

This power supply is fan cooled, the air intake is at the front 
panel and the exhaust is at the rear panel. Upon installation 
allow cooling air to reach the front panel  ventilation inlets. 
Allow minimum 10 cm of unrestricted air space at the front 
and the read of the unit. 

 
 

 

Rack Mounting 

 

The  EASY-DRIVER  power  supply  series  is  designed  to  fit  in  a  standard  19” 

equipment rack.  

 

 

Use a support bar to provide adequate support for the power 
supply.
