Note
In a short time, the switching power supply will generate
inrush current, reducing the service life of the power
switch of the input fuse box.
Pulsed or Peaked loads
The load is subject to current peaks or pulses, and the maximum current may exceed the
average current value. The power supplies only display the average current value. For
pulsed current loads, the actual current may be greater than the displayed value. At this time,
the current limit must be increased or the large power supply must be turned off.
Reverse current regenerative load
When the power supplies are connected to regenerative loads (such as transformers and
inverters), the reverse current will be fed back to the power supply and cannot be absorbed
by the power supply. For such a load that can generate reverse current, a resistor must be
connected in parallel with the power supply to avoid the inflow of reverse current. This
method is only applicable when the bleeder resistor is closed.
To calculate the resistance value (Rd) of the virtual resistor, first determine the maximum
reverse current Ir and determine the output voltage Eo.
Note
As the current decreases, the resistance of the output is
partially absorbed.
Ensure that the resistor used can withstand the power
