Background 

 

The PPX DC power supplies employ a bleed 
resistor in parallel with the output terminals.  

PPX

Load

Bleed 

resistor

 

Bleed resistors are designed to dissipate the 
power from the power supply filter capacitors 
when power is turned off and the load is 
disconnected. Without a bleed resistor, power 
may remain charged on the filter capacitors for 
some time and be potentially hazardous. 

In addition, bleed resistors also allow for 
smoother voltage regulation of the power 
supply as the bleed resistor acts as a minimum 
voltage load.  

The bleed resistance can be turned on or off 
using the configuration settings.
