Detailed Product Description

Meter type: Ammeter, Voltmeter, Frequency Meter, Power Meter(active or reactive), rotate 90 or 240 meter

Dimension: 48x48 mm, 72x72 mm, 96x96 mm, 80x80 mm, 60x70 mm, 60x60 mm, 50x50 mm,  other round type meter 

Panel meter is one kind of electric measure indicator with the direct effection of imitative display. It is suitable for AC & DC output and input distribution circuit, power plant console cabinet, power operating board and different apparatus. It is used to measure DC current, voltage & AC current, voltage, frequency and phase power. 

CNDFpanel meter  can measure the current, voltage frequency, active and reactive power, power factor in assembly equipment electrical cubes, boxes and other measurement system in industrial enterprise, chemical, metallurgy and electric textile.

1. Accuracy of current and voltage: class 1.5, accuracy of frequency, power and power factor: class 2.5, accuracy of  CNDF 48-A.V: class 2.5

2. Operation conditions: working temperature-25C~+40C, relative atmosphere humidity 85%.A few sands are allowable in the air

3. Outside mechanical applied force withstand: common type

4. Insulation strength Arcsine 50Hz, 2kV/2min. There should be no feed-through and flashover indications on the meter after the voltage tests

5. Working position: it should be mounted vertically to operate

6. Construction characters: the series meters can be divided into two types of construction,  CNDF series,ampere, voltage meters are electromagnetic series adopting repulsive construction. When meter in AC circuit, the coil can bring out a magnet field. The stable and movable iron chip repels each other because of magnet and makes the pointer rotor turn till 4 the reverse torque equality  CNDFseries frequency active reactive power, power factor meter are adjustable current type. The construction is made of electromagnetic measurement mechanism and electronic transfer .automobile, generator, handling of foul water, fire control, safe control and teaching instrument.
