Analog Ammeters
Alliance Engineering Company
Alliance Engineering Analog Ammeters are moving iron (AC) and moving coil (DC) panel instruments designed for accurate current measurement in industrial switchgear, MCC panels, distribution boards, DG panels, and control rooms. Available in 72mm, 96mm, and 144mm flush-mount square formats with a wide range of full-scale deflection ratings from 1A to 3000A (via external CT). Class 1.5 accuracy as per IS 1248 with clear, easy-to-read white dial faces and black pointer. Suitable for both AC and DC measurement applications. Manufactured by Alliance (India) under ISO 9001:2015 standards.
