Considerations
The following situations should be taken into consideration when
using the power supply.
Inrush Current
When the power supply switch is first turned
on, an inrush current is generated. Ensure there
is enough power available for the power supply
when first turned on, especially if a number of
units are turned on at the same time.
Capacitive Load
When the power supply connects to a capacitive
load, e.g., capacitor, the load is being charged
consecutively and the larger the voltage change,
the more the current grow. Also, the overshoot will
be possibly generated within the currents output,
therefore leading to output turned off thanks to
overcurrent protection from the power supply.
It is suggested to lower down the set voltage
output from power supply so that the voltage of
capacitive load decreases per certain unit time. In
addition, a block diode is necessary to keep
current from flowing back to the output terminal
of power supply. Refer to the figure below where a
block diode connects with the capacitive load in
series to efficiently prevent current from flowing
back to the power supply.
