Matchbox to debut digital voltage monitor at Oshkosh

By Janice Wood · July 18, 2011 ·

MatchBox Aeronautical Systems will introduce at Oshkosh its new addition to its product line at this year’s AirVenture, the DVM 828, a self-contained digital voltage monitor that keeps a close eye on the overall health of the aircraft’s battery and charging system.

Installation is made simple by using the aircraft’s existing cigarette lighter connector found in most airplanes, according to company officials.

By way of highly accurate voltage regulators, the DVM 828 receives its power from the aircraft, no addition batteries are need. Operating the on board microcontroller and drivers with voltage levels at or below 5 volts allows the unit to measure the battery and charging system with accuracy to the nearest tenth of a volt. The DVM 828 uses three discrete Blue 7 Segment displays with a height of .375” for easy viewing. The DM 828 automatically shifts between 12 volt and 24 volts systems.

This new addition to the MatchBox product line up will be on display at this year’s EAA AirVenture Oshkosh at PilotMall.com and Aircraft Spruce.

With its engineering and manufacturing facility based in Palm Coast, Florida, (XFL) MatchBox began as a flight school owned and operated by a retire Flying Tigers/FedX pilot and partnering with a corporate pilot/electrical engineer. The Matchbox team set their sights on a void of peripheral aeronautical products missing in the aviation market. The goal was to design and build state of the art electronics with a high degree of accuracy at reasonable costs to the avid pilot supporting safety, comfort, and convenience.
