4.1 Use as a DC Power Source
APS-1102 Programmable AC/DC Power Source 4-3
Once a diode has been connected, a load that does not consume power keeps its voltage
charged. The voltage of the load may be slightly higher due to the overshoot voltage and
should be carefully monitored.
Figure 4-1. Connection of Block Diode
b) Inductive load such as inductor
An inductive load generates a back EMF when current suddenly stops flowing, such as when
the output is turned off. A backflow diode is required to absorb the back EMF.
Connect a backflow diode in parallel with the load, as shown in Figure 4-2.
