    Description

    Product introduction:

    Square AC ammeter 84L4-A is embedded in the installation of ships or other occasions electrical equipment, measuring AC voltage with a rated working frequency of 50Hz and 60Hz, and a wide-angle electricity meter with AC current.

    The DC ammeter and the AC ammeter are very different. They cannot exchange measurements, and there is no way to exchange measurements. For high-current ammeters, the DC ammeter is actually just a 75 millivolt DC voltmeter (the millimeter on the shunt is measured). Voltage), and the internal resistance of the AC ammeter is very small (measured is the short-circuit current of the transformer secondary), which is short-circuited to the circuit, and the current can allow AC 5 amps to flow.

    1. Uses:

    Embeddedly installed on ships, locomotives, power stations, mines, metallurgy, petrochemicals or other mobile power equipment, measuring AC current voltages with rated operating frequencies of 50, 400, and 427 Hz.

    2. Main technical performance:

    Class 2.5, splash proof and vibration resistant.

    3. Conditions of use:

    Ambient temperature: -25 ~ + 55 ℃, relative temperature: <98% RH

    4. Measurement range:
