350 to 840 W Laboratory DC Power Supply
Dual Output DC Power Supply with Powerflex
The Xantrex XPF is a new type of bench power supply designed to meet the need for flexibility in the
choice of voltage and current. Typically, the maximum voltage and maximum current are not required
simultaneously. The PowerFlex design enables higher currents to be generated at lower voltages within
an overall power limit envelope. This is achieved by using the latest switch-mode technology.
The XPF Series are dual output DC power supplies with two completely independent and isolated
outputs. If required, the outputs can be wired in series or parallel to achieve up to double the maximum
voltage or double the maximum current.

The maximum current at any
voltage setting is limited by
the power envelope which is
set to give 5A at 35V rising
to 10A at 12V under all AC
supply conditions (both outputs
loaded). At lower voltages the
power is restricted by the
10 amps current maximum.
