Current Sinking
Current sinking, also referred to as down-programming, is the ability to pull current into the positive
terminal of the power supply. For example, the power supply pulls or sinks current into the positive
terminal whenever a lower output voltage is programmed. This is necessary because stored energy
from the power supply's output capacitor and external capacitance from the load, including the wiring,
must be discharged to lower the voltage at the output terminals.
The ability to rapidly transition from a higher to a lower constant voltage level greatly improves the
power supply’s output response time. At some point, some of this energy may be returned to the AC
mains by the power supply. This is the most commonly used application of the regenerative function of
the unit, which is automatic and completely transparent to the user.
Regenerative Operation
Regenerative operation is automatic and requires no programming on the part of the user. Whenever
the unit is sinking current, either by rapidly down-programming the output, or by discharging an energy
source such as a battery, the unit will return the excess energy to the AC mains. Refer to
