CE Analog Panel ammeter (91C4-A)

Uses and applications:
This series of meters is a direct imitation of power measurement display instruments, measuring DC current and voltage, AC current and voltage, frequency, power factor, phase sequence, power, synchronization instructions and other non-power measurements. It has been widely used in a variety of AC and DC transmission and distribution systems, power control panels and other electrical devices, in the industries of maritime shipping, rail transport, chemical flameproof, low voltage equipment, construction equipment, generators, machinery equipment, etc. Being able to make electrical measurement and non-power measurement, it is a high-end instrument applied in general environmental conditions.

Accuracy level:
The JY series of pointer meter: AC and DC voltmeter and ammeter to the level of 1.5 or 2.5, power meter to the level of 2.5, frequency meter to the level of 2.5, and power factor meter to the level of 2.5.
Overload ammeter:
The conventional overload multiple times should be once or twice, and it can be customized to once, twice, 3 times and so on according to the user's requirements. Its function is to indicate the approximate transient overload current value, such as the start-up current when the motor stars, and so on.
Extrinsic current shunt:
The voltage specifications of the extrinsic current shunt of DC ammeters are 150mV, 100mV, 75mV, 60mV and 50mV, which can be customized. The resistance of the conducting wire connecting the meter and the current shunt should within the range of 1525mΩ , to ensure the accuracy of the meter.
The surface of the dial:
The surface of the dial uses aluminum alloy, white paint, black ink printing or laser printing. The dial can be customized according to the customer's sample dials (overprint colors can be customized). The luminous dial uses the PC panel.
Zero regulator:
Except the reading meters without mechanical zero, all other meters have pre-positive zero regulator, used to adjust the meter's mechanical zero.
