1pcs P-40SA VU meter DB Level Header Level Audio Meter With Backlight Blue LED


 Appearance agency
1 Movable part: moving coil type
2 Appearance size method: see figure
3 degree plate: see picture
4 Pointer material: Nickel silver strips
   Pointer color: orange
   Pointer swing direction: from left to right
   Pointer length: From the central axis to the needle end 19.5± 1 mm
   Pointer width: 0.45 ± 0.05 mm
5 The direction of use of the electric meter: vertical
 
 Electrical performance
6 Standard test conditions: Temperature is 20℃, humidity is 70%, when there is no difference in test results,
It can also be tested at room temperature and humidity
7 Current sensitivity: the pointer is at the zero scale to the maximum scale (full scale position), the sensitivity is 300 uA ± 10%
8 Internal impedance: 800 Ω ± 10%
9 Insulation resistance: 500V DC plus 50M ohm or more for the outer box of the meter and the electrical circuit. The insulation resistance of the meter housing and the electrical circuit is tested with a 500V DC voltage.
10 Zero position: The meter uses the standard posture, the front end of the pointer and the center of the zero scale are used as the reference, and the overlapping tolerance of the pointer and the zero scale is ±1mm
11 Balance: The allowable error range of the meter when the standard position is tilted forward and backward by 90 degrees is ±1mm
12 Pointer sticking: Instantly add the full-scale current three times the overcurrent, and slowly decrease to the reading of 1/2 of the current sensitivity, at this time the pointer will return to within 1/3 of the scale of the scale board
13 Friction: When adding current to the meter, and slowly increasing or decreasing to a certain value, the error range of the indication point is ±1mm
14 Braking: Instantly add 2/3 of the current value of the scale plate, within one second from the start to the pointer indicating position
 
 Special test
15 Overload test: Input ten times the full scale current every five seconds. This action is repeated nine times. Each time is 0.5 seconds. After this test, items 7-14 remain normal
16 Vibration test: After the electric meter is packaged, it performs 1,000 up and down 4mm vibrations per minute on the vibration plate, 10 minutes in each direction. After this test, the 7-14 items remain normal
17 Impact test: After being packaged, the meter is dropped from a height of 30 cm onto a 3cm thick wooden board, tested in X.Y.Z. three directions, and 7-14 items remain normal after this test.
18 Reliability test: After 100,000 calibration point current input, the current sensitivity limit is still within the standard
19 Environmental impact test: temperature 50℃, humidity 85%, lasting 100 hours, after this test 7-14 items remain normal
20 Terminal pull test: The terminal must withstand a pull of 1 kg for 60 seconds without being affected
 
Other
21 Operating temperature limit: -10℃ to＋60℃ RH 35 to 85%
22 Storage temperature limit: -20℃ to＋60℃ RH 35 to 85%
    Do not place the meter under direct sunlight, and store the meter in the packaging box to prevent foreign objects from entering the interior of the meter
23 Soldering condition: Put the terminal about 3 mm into the tin plate at 230℃ for 3.5 seconds. After this test, items 7-14 remain normal
 Soldering tin temperature: Hold the solder gun at 350℃, contact the terminal for 3.5 seconds, and the front end of the terminal is about 3mm in contact with the solder gun. After this test, the 7-14 items remain normal
24 Anti-static: Use dry nylon cloth to test three times in the same direction on the surface of the transparent cover. The difference of the pointer on the scale is less than 1/3 of the length of the scale, and it will return to the zero position after three seconds.
25 Bulb specification: two blue LED HX-504BC2E 3.0-3.6V 20mA
The 26 VU meter is very modern and dynamic, with a car instrument style. It is very suitable for refitting car power amplifiers, computer active speakers, speech amplifiers, and other equipment.
