Panel Ammeter for AC Circuits

This analog panel meter measures AC current from 0 to 20 A with Class 2.5 accuracy. It fits a standard 50 mm square cut-out and mounts vertically. The clear scale and fine-tuning button help electricians, hobbyists and automotive technicians verify circuit current quickly.

Measurement Range and Limits

The movement covers 0–20 A AC, giving enough headroom for typical low-voltage lighting, accessory feeds and small appliance branches. It will not display DC current, nor will it read loads above 20 A without an external shunt. Installations requiring true-RMS response or data logging need a different instrument class.

Mounting Hardware and Calibration Aid

A 5 mm mounting thread and 3 mm secondary thread secure the 50 mm deep body in a panel. The front-panel adjustment button lets the user zero the needle before use, removing parallax error without opening the case. No test leads, shunts or configuration software are supplied.

Questions about this item

Will this 50 mm panel ammeter fit alongside my existing 50 mm gauges in the same dashboard cut-out?

The panel size is 50 mm by 50 mm with a 50 mm overall depth, so it matches other 50 mm instruments and uses a vertical mount.

How do I verify the needle reads correctly after wiring it into my AC circuit?

Apply a known AC current up to 20 A; the pointer should indicate within Class 2.5 accuracy and the fine-tuning button lets you zero the dial.

Does the package include mounting hardware or do I need to source screws separately?

The meter comes with the panel unit and a 5 mm thread diameter stud; mounting screws or a bracket are not included and must be purchased separately.
