GETTING STARTED

Reverse Current: When the power supply is connected to a
Regenerative load regenerative load such as a transformer or
inverter, reverse current will feed back to the
power supply. The PHU power supply cannot
absorb reverse current.
For loads that generate reverse current, connect an
external resistor in parallel with the power supply
to bypass the reverse current.

This description only applies when the bleed
resistance is off.

PHU Resistor Load

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

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

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