4-digit AC current and frequency meter

The Autonics MT4Y-AA-40 is a digital panel meter with a 4-digit 7-segment LED display and 14.2mm character height. It measures AC current and frequency across seven selectable input ranges up to 5A. The unit operates on 100-240VAC 50/60Hz power supply.

Who this suits and who should look elsewhere

This meter suits electricians and panel builders who need a compact 4-digit readout for AC current monitoring in control cabinets. It is not for users who require DC current measurement, data logging, or analog output signals. Buyers needing higher current ranges without external shunts should consider other options.

Key specification: 0-5A AC input range

The maximum direct AC current input is 5A across the 50Hz and 60Hz power supply frequencies. This single figure determines whether the meter can be connected directly to the circuit or requires a current transformer for higher loads.
