VP-50 Product Information Priced at under $1500, the VP-50 packs a lot of features in a small package with a small price. It brings modern technology to experimental aircraft to simplify wiring and provide advanced electrical system capabilities. It replaces switches, circuit breakers, indicators, voltage alarms, trim relays, shunts, voltage converters and a host of other products. Plus, it makes wiring a modern electrical system simpler than traditional antiquated alternatives.The VP-50 installs in your instrument panel and provides eight switches to control the avionics and trim system. It supports a single bus, single or dual-battery, single or dual-alternator electrical configuration. The lighted liquid-crystal display shows overvoltage and under-voltage alerts, short-circuit and over-current alerts, trim position, current draw of the system and individual devices, and bus voltage. It is built using the latest technology, yet is based on time-honored electrical architectures. The system has the flexibility to adapt to each unique aircraft. Features and Capabilities The VP-50 provides the following functions: |

| Using the VP-50 You turn on the VP-50 electrical system by flipping on the master switch. The VP-50 tells you there are no electrical shorts and the system status is OK. It indicates the trim position, battery voltage, and overall aircraft current draw. You start the engine using the start/mag switch (located separately from the VP-50 on the instrument panel), then flip the alternator switch to Primary. The VP-50 panel is shown below: |

You then turn on the avionics and lights using the switches on the front of the VP-50. Each switch can be assigned to one or more electrical device. For example, you could have all your avionics on one switch, the boost pump on another, and the landing lights on another switch. The strobe and nav lights can be grouped on different switches. If you have a low-voltage condition during flight, the big red button will alert you by flashing red and the display with indicate a low-voltage alarm. This means you likely have a failed alternator or voltage regulator. You acknowledge the alert and then move the alternator switch down to select the backup alternator. You then load shed by turning off switches which are tied to non-essential loads. When closer to the airport, you can turn on each of the switches as necessary.While the trim is running, the display indicates the position of the trim tab. When a switch is down (off) the LED tip light is off and when it is up (on) the LED light is green. If a device on that switch is faulted (short circuit or over-current), then the tip light flashes red. The display will tell you which circuit is faulted, and you can attempt to manually reset the circuit or leave it off. The display also shows the total current draw of the electrical devices connected to the VP-50. This is a nice feature that allows you to compare real-time current draw with the capacity of your alternator, and it also eliminates the need to install shunts or hall effect sensors. Once you’ve shut the engine down, simply shut off the electrical system with the master switch. Wiring with the VP-50 Wiring your airplane is a serious project. No one can make it easy, but we can make it a lot easier. Rather than point to point to point wiring, you wire from the Vertical Power Control Unit (CU) to the power input on the electrical devices. Run a wire from the CU to the landing light. Run a wire to the EFIS. Run a wire to the  transponder. Run a bundle of five wires to a trim servo. Run a wire from each trim switch to the CU. Until you’re done. We provide complete instructions, how-to guides, tool rentals, wiring harnesses and wiring diagrams to assist with your project. You can throw out your complicated bus architectures and wiring diagrams – all the wiring diagrams, templates, and instructions are already created for you and available here. |
