Reverse Current:
Regenerative load

When the power supply is connected to a
regenerative load such as a transformer or
inverter, reverse current will feed back to the
power supply. The PSU power supply cannot
absorb reverse current. For loads that create
reverse current, connect a resistor in parallel to
the power supply to bypass the reverse
current. This description only applies when the
bleed resistance is off.

Reverse current

Note

The current output will decrease by the amount of
current absorbed by the resistor.

Ensure the resistor used can withstand the power
capacity of the power supply/load.

Reverse Current:
Accumulative
energy.

When the power supply is connected to a load
such as a battery, reverse current may flow
back to the power supply. To prevent damage
to the power supply, use a reverse-current-
protection diode in series between the power
supply and load.
