GETTING STARTED

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.
Note
By default the bleed resistance is on. For battery
charging applications, be sure to turn the bleed
resistance off as the bleed resistor can discharge
the connected battery when the unit is off.
Internal Resistance
Background
On the 2260B, the internal resistance of the
power supply can be user-defined in software.
(Internal Resistance Setting, page 31). When the
internal resistance is set it can be seen as a
resistance in series with the positive output
terminal. This allows the power supply to
simulate power sources that have internal
resistances such as lead acid batteries.
