Reverse Current: 
Regenerative load 

When the power supply is connected to a 
regenerative load such as a transformer or 
inverter, reverse current will feed back to the 
power supply. The 2260B power supply cannot 
absorb reverse current. For loads that create 
reverse current, connect a resistor in parallel to 
the power supply to bypass the reverse 
current. This description only applies when the 
bleed resistance is off.

Reverse current

 

 Note 

The current output will decrease by the amount of 
current absorbed by the resistor. 

Ensure the resistor used can withstand the power 
capacity of the power supply/load.
