Instructions

Use and application:

Voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronization instructions and other non-electrical measurement.Mainly used in marine vessels, rail transit , The chemical explosion-proof, low-voltage equipment, construction equipment, generating units, machinery and equipment industries AC and DC transmission and distribution systems, power control panels and other electrical equipment. 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. Scale dial line and pointer design in line with the German DIN43790 and DIN43802. The shape and size of the instrument are manufactured according to GB / T1242 and IEC61554. Elite Instruments All products are CE certified and IS0; 9001 certified.

Plate surface shell:

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

Temperature changes caused by the amount:

Reference temperature is 23 ℃ ± 2 ℃. 13 ℃ ~ 23 ℃ and 23 ℃ ~ 33 ℃ temperature range, the temperature changes allow the amount of change is not greater than ± 100% of the index.

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

Accuracy level:

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

Overload ammeter aspects:

Overload times 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 instantaneous value of the overload current, such as the start-up current when the motor starts.

External current shunt side:

DC ammeter external shunt voltage drop specifications 150mV, 100mV, 75mV, 60mV and 50mV, etc. can be customized by the user requirements.~25mΩTo ensure instrument accuracy.

Surface Dial:

surface Dial: aluminum alloy, 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 Regulator:

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:

JY series 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 Instrument input signal the same, different specifications can replace the dial, replacement, the accuracy of the same.
