VF0.4-150

VF0.4-150 voltmeter for aircraft AC networks

VF0.4-150 is an aircraft analog voltmeter used for measuring high-frequency alternating current voltage in onboard electrical systems. The instrument provides direct pointer indication and is intended for aircraft AC networks operating at aviation frequency. It is installed where the crew or maintenance personnel need visual monitoring of AC voltage. The voltmeter is a measuring instrument only; it does not regulate voltage and does not provide circuit protection.

AC voltage measurement through VF0.4-150

The voltmeter measures AC voltage directly in the monitored circuit. It is connected without a voltage transformer, so the measured circuit voltage must correspond to the instrument range and connection requirements. The working part of the scale is intended for normal voltage monitoring in aircraft AC power systems. Correct indication depends on proper wiring, stable frequency, serviceable internal measuring mechanism and compliance with the rated voltage range.

VF0.4-150 in 400 Hz aircraft systems

The instrument is designed for aircraft electrical networks with nominal 400 Hz frequency and can operate within the specified high-frequency range. Such systems are used in onboard power supply circuits for avionics, lighting, control equipment and other aircraft consumers. Because aircraft AC networks may vary by configuration, the voltmeter should be selected according to the installed system voltage, frequency range and panel layout. Similar instruments may differ by scale range, accuracy class or mounting size.

Panel installation of VF0.4-150

VF0.4-150 has a compact round case for installation in a panel opening. The dial is designed for quick visual reading, with a clear scale and pointer indication. The instrument is suitable for aircraft panels where space is limited and stable readability is required. When replacing the voltmeter, the mounting diameter, scale range, connection type and panel marking should be checked before confirming interchangeability. Direct replacement by appearance alone can lead to incorrect selection.

Identification and ordering of VF0.4-150

Before ordering VF0.4-150, the full marking should be checked against the aircraft electrical system documentation or product passport. It is important to confirm the voltage range, working frequency, mounting diameter, accuracy class and method of connection. For correct selection, provide the aircraft type, electrical system application, existing instrument marking and a photo of the scale or rear connection if available. The product is also known under alternative designations VF0.4-150 and ВФ0,4-150.
