Use and application of:

This series instruments are direct analog display electrical indicating measuring instruments, measuring DC current, voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronization instructions and non-electric measurement. Widely used in maritime shipping, rail transportation, chemical explosion, low-voltage equipment, construction equipment, generators, machinery and equipment industries, direct-current transmission and distribution system, electric control panel and with other electrical devices. Acting on the electric measurement and non-electric measurement, is applicable to the environment General requirements general middle-grade instruments.

Standards and certification:

Elite Series pointer instrument instrument electronics are in accordance with GB/T7676-1998, digital instruments are produced according to GB/T22264-2008 standard, its security in accordance with GB4793 and IEC61010 standards. Dial the tick and pointer design in accordance with German standards DIN43790 and DIN43802. Instrument of shape and hole size in accordance with GB/T1242 and IEC61554 standards. Elite instrument electronics companies by State CE certification for all products, and IS0;9001 certification.

Panel meter case:

JY Series Base flame retardant TBT Plastic, Vicat temperature is 130 degrees. Shell Made of flame retardant ABS plastic, Vicat temperature of 85 degrees.

Temperature-induced change:

The reference temperature of 23 ℃ ± 2 ℃. 13 ° c ~23 ° c and 23 ° c-33 ° c temperature range, temperature effect allows you to change content index of not more than ± 100%.

Installation position and installation of:

Unless otherwise specified, usually instruments were installed in vertical position. Other installation locations such as: horizontal, tilted installation can be produced according to customer requirements. Corresponding accuracy class is valid only for prescribed installation position. Instrument-right angle 90 ° and 250 ° wide, two indicates the angle.

Effect of vibration and shock resistance:

Vibration resistance : Conform to IEC60068-2-6 standards; Frequency range: 10-55-10Hz; Amplitude: ± 0.15mm ± 0.3mm.

Sweep cycles: 5 times; Sweep rates: 10ct/min; Maximum acceleration: 147m/S2 (15G), 490m/S2 (50g).

Effective value of acceleration: 6.06g; Duration: 15min. resistance to mechanical impact, in line with the IEC60068-2-27 standard.

Accuracy class:

JY Series Pointer instrument: AC-DC voltmeter and ammeter to 1.5 or 2.5, power meter 2.5Class, frequency tables 2.5Level, power factor meter to 2.5.

Overload current meter:

Overload conventional 1 time and twice times overload capacity, can be customized by the user requirement for 1 time, 2Times, 3 times, and so on. Whose role is to indicate the instantaneous overload current worth, such as motor starting current.

External shunts:

DC ammeter shunt voltage drop factor 150mV, 100mV, 75mV, 50mV and 60mV can be customized by the user. Instruments connected to the shunt resistance of conductors at 15∼25mΩTo ensure the instrument accuracy.

Dial:

Surface Dial: aluminum alloy material, end of white paint, black ink or laser printer printing. Can be customized according to customer sample dial (customizable multiple color printing). Luminous dial PC Board.

Zero adjuster:

With no mechanical zero reading instruments, all other instruments are leading zeros level regulator to adjust the meter mechanical zero.

Advantages of products (replaceable dial):

JY Series Pointer instrument, open the seal, insert or dial out. AC ammeter every transformer secondary current is the same, you can replace the dial, after the replacement, accuracy is not changed; DC ammeter just shunt signal at the output the same or instrument input signal are the same, different specification can replace the dial, after the replacement, accuracy is not changed.
