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.
