use And applicable:

this Voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronization instructions and other non-electrical measurement.Many used in marine vessels, rail transportation, electricity, Chemical explosion-proof, low-voltage equipment, construction equipment, generating units, machinery and equipment industries , DC transmission and distribution systems, power control panels and use other Electrical equipment. Applies to electrical and non-electrical measurement, is applied to environmental conditions general Requirements of the more generic high-end instruments.

standard And certification:

Elite electrical instrumentation series pointer meter Yes According to GB / T7676-1998, Digital instrument is in accordance with GB / T 22264-2008Standard production, and its safety performance in accordance with GB4793 and IEC61010 standard production. Dial scale and pointer design in line with the German DIN43790 and DIN43802 standard. Meter shape and hole size in accordance with GB / T1242 and IEC61554 standard production. Elite electrical instrumentation the company All products through the country CE certified and available IS0; certificate.

Board table shell:

JY series The base is flame retardant TBT Made of plastic, Vicat temperature of 130 ℃. shell Made of flame-retardant ABS plastic, Vicat temperature 85 ℃.

The amount of change caused by temperature:

Reference temperature is 23 ℃ ± 2 ℃ .13 ℃ ~ 23 ℃ and 23 ℃ ~ 33 ℃ temperature range, the temperature change is not allowed to change the level index of ± 100%.

Installation location and Installation:

Unless otherwise specified, the instrument is normally mounted in a vertical position Other installation positions such as horizontal installation and tilting installation can be made according to customer requirements The corresponding accuracy level is valid only for the specified installation position The instrument is divided into right angle 90 ° and wide angle 250 ° °, two kinds of indication angle.

Anti-vibration and impact:

Anti-vibration : Conforms to IEC60068-2-6 standard; Sweep range: 10-55-10Hz ; Displacement amplitude: ± 0.15mm, ± 0.3mm.

Sweep cycle number: 5 times; Sweep rate: 10ct / min ; Maximum acceleration: 147m / s2 (15g), 490m / s2 (50g).

Acceleration RMS: 6.06g; Vibration time: 15min. Anti-mechanical shock, in line with IEC60068-2-27 standard.

Accuracy class:

JY series Pointer instruments: AC-DC voltmeter and ammeter in 1.5 or 2.5, power meter for 2.5 level, the frequency table 2.5, power factor meter for the 2.5 level.

Overload ammeter:

Overload multiple of conventional 1 times and 2 times the overload factor, can be customized to 1 times the user requirements, 23 times, etc. Its role is to indicate the approximate value of instantaneous overload current, such as the start-up current when the motor starts.

Attached Current Shunt:

DC ammeter external shunt voltage drop specifications 150mV, 100mV, 75mV, 60mV and 50mV, etc. can be customized by the user requirements. Instrument and shunt connection wire resistance requirements in 15~25mΩ, to ensure that the instrument accuracy.

surface The dial:

surface Dial: aluminum alloy material, white paint, black ink printing or laser printing printing. Can be customized according to customer-like dial (customizable variety of colors overprint.) Luminometer dial with PC board.

Zero adjuster:

In addition to no mechanical zero reading meter, all the rest of the instrument are pre-zero position regulator, used to adjust the instrument mechanical zero.

Advantages of the product (replaceable dial) :

JY series Pointer instrumentation , AC ammeter as long as the transformer secondary current is the same, you can replace the dial, replace, the accuracy of the same; DC ammeter as long as the shunt output of the same electrical signal or instrumentation input The same electrical signals, different specifications can replace the dial, replacement, the accuracy of the same.
