Not only do the VA-1A and VA-1A-XX provide pilots with precision voltage (to .1 volts) and Amps (to .1 Amps), but it keeps a watchful eye on the electrical system. Both systems have a "Discharge" light for low voltage situations, as well as a "High Voltage" warning light for over-voltage situations.

The systems also come complete with an external warning line that can be attached to a warning device, such as an Electronics International AL-1 Warning Light, AV-17 Voice Annunciator or ATG-1 Tone Generator, or myriad other warning devices.

Discharge Warning Light: For a 12 volt system, the light will be on when bus voltage falls below 12.8 volts (+/- .2 volts). For a 24 volt system, the light will be on when the bus voltage falls below 25.6 volts (+/- .4 volts). The voltage signal is picked up on the red power lead to the instrument.

High Volts Light: For a 12 volt system, the light will be on when the bus voltage exceeds 15.4 volts (+/- .3 volts). For a 24 volt system, the light will be on when the bus voltage exceeds 30.8 volts (+/- .6 volts). The voltage signal is picked up on the red power lead to the instrument.

External Warning Line: Both the VA-1A and VA-1A-XX have an external warning line that activates during a "High Volts" or "Discharge" scenario. The line is normally open, but when activated, it pulls to ground. You can hook the external warning line to any Electronics International warning device, such as an Al-1 warning light, AP-7 Annunciator Panel, ATG-1 Tone Generator or the AV-17 Voice Annunciator.

12/24 volt switch: A selector switch is located on the back of each VA instrument, which allows the instrument to be configured for either a 12 volt system or 24 volt system.
