VERTICAL POWER VP-50

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. 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. Components The VP-50 includes: • VP-50 Switch Panel. • VP-50 Control Unit. • Switch Panel to Control Unit cable. • Software update cable. • Optional aircraft wiring harness.

Features

Supports a single bus electrical system, single or dual battery, single or dual alternators. 14 or 28 volt systems. Built-in switching and circuit protection for 21 circuits: (4) 2 amp max, (10) 5 amp, (2) 10 amp, (3) 18 amp, (2) trim circuits. Each circuit can be set for a circuit breaker value between 1 and the max value. Circuit protection functions include short circuit, over-current, and current fault alerts (alarms when device draws no current when on, such as a burned out landing light). 2-axis trim circuits for pitch and roll trim. Trim position display. Runaway trim protection. Pressing the opposite trim switch stops the trim motor, then disconnects the trim switches after 3 seconds. Backup pitch trim switch can be used to center trim. Variable speed pitch trim, based on external flap position switch or airspeed switch. Supports standard trim switches on the stick such as those on the Ray Allen, Infinity stick grip, or CH Products sticks. Real-time display of electrical system status and faults, total system current draw, and bus voltage. (you don’t need to install any shunts or hall effect sensors). Displays of current draw of each electrical device. Displays voltage of one or two batteries. Wig wag (pulse) the landing lights. Switch Panel includes 6 on/off switches and 2 momentary switches. Alerts for nine external switches like door open, canopy open, etc. Inputs for additional external switches. Use the built-in switches or add other switches. Each circuit is fully configurable. Over-voltage protection and low-voltage alarms. Dual-alternator support – pilot selects which alternator is on. Separately, you must wire the master switch, mag switch, starter switch, dimmers, and flap switch.
