Product Identity

The Autonics MT4W-AV-48 is a digital panel meter designed for monitoring AC voltage and frequency in industrial control panels. It suits electricians and maintenance engineers who need a clear, single-unit readout for power distribution or motor circuits.

Build and Connections

The unit uses a red 4-digit 7-segment LED display with 14.2mm character height and a maximum range of -1999 to 9999. Input specifications cover 0-500V, 0-250V, 0-110V, 0-50V, 0-20V, 0-10V, 0-2V and 0-1V ranges, while the power supply accepts 100-240VAC at 50/60Hz.

Pre-Installation Checks

Verify that the panel cut-out matches the 48mm form factor and that the supply voltage at the mounting location falls within 100-240VAC. Confirm the circuit voltage does not exceed 500V AC and that the required measurement range is among the eight selectable inputs.
