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.
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
