Inductive Load
When the power supply connects to an inductive
load, e.g., inductor, which generates a back EMF
(Electromotive Force) when output current is
accidentally turned off, a backflow diode is
necessary for absorbing the back EMF, which may
cause irreversible damage to the power supply.
Refer to the following figure where a backflow diode
connects with the inductive load in parallel to
effectively absorb the possible back EMF.

CAUTION
Ensure the connected diode meets the following
specifications between the load, either capacitor or
inductor, and the ASR-2000 series power supplies.
 Maximum reverse voltage: 600 V or higher
 Maximum forward current: 15 A or more for
100V range, and 7.5 A or more for 200V range
