VP-X Sport Electrical System

When you're flying an airplane, it’s critical to be able to monitor the status of your electrical system. If you have a glass cockpit, it's even more critical. Only Vertical Power gives you the level of detail and control you need for today’s electric aircraft. The VP-X 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.

The VP-X is a Better Way to Wire and Fly Your Airplane

The Vertical Power VP-X Electronic Circuit Breaker System gives you an unprecedented level of detail and control of your electrical system, while at the same time greatly simplifying wiring. With flap, trim and other functions built right into the VP-X, you just wire directly from the VP-X to each electrical device. You no longer have to install circuit breakers, bus bars, relays, trim and flap modules, shunts, e-bus diodes, or other complex wiring on the back side of the instrument panel.

The VP-X System

VP-X Advantages

• Wire from the VP-X directly to each electrical device
• Detect short circuits, over-current faults, open circuits (no current draw)
• User-configurable circuit breaker values for each circuit
• Backup circuit capability for critical avionics
• Solid-state design – no arcing, no moving parts

EFIS Integration

• Visually monitor the health of your electrical system
• View and control the status of individual circuits
• Immediate notification of circuit faults with the ability to quickly respond
• Displays for individual and total current draw, main battery voltage, aux battery voltage (if installed), trim position, flap position, and starter engagement

Flap Control

• Built-in solid-state flap motor control
• Intermediate flap stops or momentary control
• Flap over-speed warnings
• Flap motor run-on protections
• Disable the flap down switch above a specified airspeed
• Backup flap controls on the EFIS
• Flap position display on EFIS

Trim Control

• Built-in solid-state trim motor control
• Runaway trim protection
• Variable-speed pitch trim based on airspeed
• Backup trim controls on the EFIS
• Trim position display on EFIS

Switch Inputs

• Each switch is configurable to control one or more electrical devices
• Flexibility to use any style of panel-mounted switch

Wig-wag Control

• Built-in landing light wig-wag control
• Adjustable warm-up period
• Landing lights, when turned on, are steady on the ground then automatically pulse when the aircraft is in the air

Alternator Protection

• Alternator over-voltage protection
• Single or dual alternator support

Starter Protection

• Starter disable when engine running
• Starter engaged annunciator on EFIS

 

• Reduces parts count and complexity
• Includes built-in solid-state trim motor control
• Includes built-in solid-state flap motor control
• Includes built-in landing light wig-wag control
• Allows you to configure circuit breaker values for each circuit
• Lets you use any style of panel-mounted switch
• Provides easier system changes or expansion
• Reduces pilot workload
• Delivers more control and information
• Clearly shows current draw for each circuit
• Detects short circuits, over-current faults, and open circuits (no current draw)
• Provides runaway trim protection
• Warns of flap over-speed
• Protects against flap motor run-on
• Disables flap down switch above specified airspeed
• Disables starter when engine is running
• Allows you to easily monitor and control your electrical system from your EFIS
• Eliminates panel-mounted breakers and fuses, opening more space for avionics and accessories
• Provides “intelligent” control such as automatically turning landing light wig-wag on & off, or varying trim speed, based on user-specified airspeeds
• Delivers higher reliability and longer life – no arcing, no moving parts
• Promotes a clean, modern cockpit
