VP-X is for use only with experimental and light sport aircraft.
Note: Either a wiring harness kit or connector-only kit is required with the VP-X system.
integrates with many popular EFIS products enabling you to monitor and control
your entire electrical system on the EFIS display. In addition using the EFIS
for attitude, navigation, and engine information, you now can use the EFIS
display to monitor the health of your electrical system, view and control the
status of individual circuits, and respond to circuit faults.
Power offers these capabilities through the use of a patented electronic
circuit breaker (ECB) technology that is at the core of all of our products. Of
course, ECBs provide circuit protection like old-fashion thermal circuit
breakers, but ECBs do a lot more than just detect circuit faults. ECBs are
intelligent, configurable, and offer capabilities not otherwise available with
old-style breakers. For example, ECBs can detect a burned-out landing light or
disable the starter circuit while the engine is running.
supports a single bus electrical architecture with a single or dual alternator
configuration. It additionally supports the ability to measure the voltage on
an aux battery. There are enough circuits to wire a typical RV (including the
RV-10), Glastar, Lancair Legacy, Velocity, Cozy, or other 2 to 4 place
Wiring With the VP-X
Wiring your airplane is a serious project. No one can make it easy, but we can
make it a lot easier. We provide complete instructions, how-to guides, tool
rentals, wiring harnesses and wiring diagrams to assist with your project.
than a mess of wiring behind the panel, you wire from the VP-X directly to each
electrical device. Run a power wire from the VP-X to the landing light. Run a
power wire to the EFIS. Run a power wire to the transponder. Run a bundle of five
wires to a trim servo. Run two wires to the flap motor. And so on. Run a small
wire from each trim switch, the flap switch, and panel switch to the VP-X.
Then use the setup menus in the EFIS to configure your system. You specify
which power pin each device is connected to, what the circuit breaker values
are, and which switch should turn each device (or group of devices) on or off.
You can use any type of switch you like to match your panel.
DualBuss™ Technology The VP-X Pro
includes Vertical Power’s new DualBuss™ technology that has two independent
power busses in a single system, delivering unprecedented levels of redundancy
and safety. Builders can now easily divide avionics and other electrical loads
between two power busses, and should one bus controller fail the other bus will
continue to operate independently and be able to provide power to the starter
contactor. Each bus controller is powered by an independent power supply and
Below is a table showing the cost of various components for
your aircraft to achieve a basic level of functionality to the VP-X. As you
look at each component, consider the added complexity for the wiring, learning,
troubleshooting, and mounting requirements for each one. We think you’ll find
the cost and simplicity of the VP-X is very competitive.
