Panel Meter

NP96, NP72, NP48 series panel 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 NP48-A.V: class 2.5

2. Operation conditions: working temperature -25°C~+40°C, 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, NP96, NP72, NP48 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 NP96/NP72/NP48 series frequency active reactive power, power factor meter are adjustable current type. The construction is made of electromagnetic measurement mechanism and electronic transfer

7. NP96/NP72/NP48 ampere and voltage meter measurement

NP96, NP72, NP48 ampere and voltage meter measurement

1. 0.5A~30A (directly connecting)

2. 30A~10kA (with current transformer/5 5A table)

3. 15A~600V (directly connecting)

4. 450V~460kV (with current transformer/100 100V table)
