Connecting the Load
E3632A User’s Guide 159
With remote voltage sensing, a feature included in the
Agilent E3632A power supply, it is possible to connect the
input of the voltage feedback amplifier directly to the load
terminals so that the regulator performs its function with
respect to the load terminals rather than with respect to the
power supply output terminals. Thus, the voltage at the
power supply output terminals shifts by whatever amount is
necessary to compensate for the voltage drop in the load
leads, thereby maintaining the voltage at the load terminals
constant.

Load consideration
Capacitive loading
In most cases, the power supply will be stable for almost
any size load capacitance. Large load capacitors may cause
ringing in the power supply’s transient response. It is
possible that certain combinations of load capacitance,
equivalent series resistance, and load lead inductance will
result in instability. If this occurs, the problem may often be
solved by either increasing or decreasing the total load
capacitance.
