AC Voltage Panel Meter

The Autonics M4W-AV-6 is a digital panel voltmeter designed for AC voltage monitoring in industrial and control-panel applications. It mounts directly into a standard cut-out and provides a clear local read-out of the measured potential.

Suits single-range AC monitoring.

This meter suits operators who need a dedicated 400V AC indicator with a fixed input range. It is not for users who require DC measurement, autoranging capability, data logging, or configurable alarm outputs.

14 mm red LED display height

The 3½-digit read-out uses 14 mm high red 7-segment characters, giving a maximum displayed range of 0 to 400. This character size determines readability at a distance and in bright ambient light.

Questions about this item

What AC supply voltage must be present to power the M4W-AV-6 indicator?

The unit is a 400 V AC panel voltmeter; it requires a compatible 400 V AC source for the measurement input.

Can the 14 mm LED display be read clearly next to older analogue meters on the same panel?

Yes, the 3½-digit 7-segment LED with 14 mm character height provides high contrast that remains visible alongside legacy dial instruments.

How do I verify the M4W-AV-6 is measuring correctly after wiring it in?

Apply a known AC voltage within the 0 to 400 V range and confirm the 3½-digit LED shows the expected value.
