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 PSW 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.
PSW Load Resistor
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.
