Megger VF5 Voltage Detector
Designed to check for the presence of AC voltage without contact, the Megger VF5 Voltage Detector provides low and medium voltage detection modes across 12 V AC to 1000 V AC at 50/60 Hz. A bright red LED within the white nylon tip combines with an audible sounder and vibration alert to indicate detected voltage. Safety compliance is CAT IV 1000 V, ingress protection is rated IP67, and the rubber over-moulded body is designed for durability.
Low voltage mode covers 12 V to 1000 V AC, using a flashing red LED, beeping sounder and vibration, with the response rates increasing as the detector moves closer to the voltage source. Medium voltage mode covers 100 V to 1000 V AC, using a steady red LED, rapid beeping and constant vibration. A built-in bright-white LED torch and tip-mounted work light assist in poor light, while automatic power-off after approximately five minutes of inactivity helps conserve battery power.
Key Benefits
- Checks for the presence of AC voltage through non-contact detection
- Low and medium voltage modes cover detection from 12 V AC to 1000 V AC
- Visual, audible and vibration warnings provide three forms of indication
- Warning rates increase as the detector moves closer to the voltage source in low voltage mode
- Automatically changes to medium voltage mode when voltage between 100 V and 1000 V is detected
- Bright-white LED torch supports work in poor lighting conditions
- Tip-mounted white LED provides additional light around the detection point
- Automatic power-off after approximately five minutes of inactivity conserves battery power
- Low battery indication identifies when the battery voltage is too low for reliable operation
- Convenient pocket-size design supports portable use

Specification Notes
- The VF5 indicates live AC circuits only. It cannot determine the actual voltage and must not be used to verify that a circuit is de-energised. It is not a Safety Test Lamp
- The detector is unable to detect voltage on armoured or sheathed cable, cable in conduit, cable behind panels or cable within metallic enclosures
- Insulation type and thickness, distance from the voltage source, shielded wires and other factors may affect reliable operation and the point at which the detector changes from low to medium voltage mode
Meta Description
