42L6 power meter

Uses and application areas:

Voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronous indication and other non-electrical measurement.Many used in maritime ships, rail transit , Chemical explosion-proof, low-voltage equipment, construction equipment, generating units, machinery and equipment industries AC and DC power transmission and distribution systems, power control panel and other electrical equipment on the role of electrical measurement and non-electrical measurement is applicable General requirements in the environmental conditions are more general in the high-end instruments.

Standards and Certification:

The instrument is in accordance with GB / T7676-1998, digital instrument is in accordance with GB / T22264-2008 standard production, the safety performance in accordance with GB4793 and IEC61010 standard production. Dial scale and pointer design in line with the German DIN43790 and DIN 43802. The shape and opening size of the instrument are manufactured according to GB / T1242 and IEC61554 standards.Our products have passed the national CE certification and got IS0; 9001 certification.

Table shell side:

Series base by the flame-retardant TBT plastic, Vicat temperature 130 ° C. Shell made of flame-retardant ABS plastic, Vicat temperature 85 ℃.

Temperature-induced changes in the amount of:

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 methods:

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 of impact:

Anti-vibration: in line with IEC60068-2-6 standard; sweep range: 10-55-10Hz; displacement amplitude: ± 0.15mm, ± 0.3mm.

Sweep frequency: 10ct / min; maximum acceleration: 147m / s2 (15g), 490m / s2 (50g).

Vibration time: 15min. Anti-mechanical shock, in line with IEC60068-2-27 standard.

Accuracy level:

Top macro series pointer instrument: AC-DC voltmeter and ammeter in 1.5 or 2.5, power meter for the 2.5, the frequency table is 2.5, power factor meter for the 2.5 level.

Overload ammeter aspects:

Overload multiples of conventional 1 times and 2 times the overload factor, can be customized by the user requirements for 1 times, 2 times, 3 times, etc. Its role is to indicate the approximate value of instantaneous overload current, such as the motor starting current.

External current shunt side:

DC ammeter attached 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 the 15 ~ 25mΩ within to ensure that the instrument accuracy.

Surface Dial:

Surface dial: aluminum alloy material, white paint, black ink printing or laser printing printing. Can be customized according to customer sample dial (can be customized a variety of colors overprint.) Luminometer dial with PC board.

Zero adjuster aspect:

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.

The advantages of the product (replaceable dial) aspects:

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 signal (such as the output signal, The same or the instrument input signal the same, different specifications can replace the dial, replacement, the accuracy of the same.
