TN-90A VU Meter DB Level Header Power Supply Driving Board

Detailed Information About The Product:

Electrical Characteristics:standard test conditions temperature: 20 Celsius humidity 70% . Can also be tested under normal temperature and humidity.The influenza degree pointer at the zero scale to the maximum scale sensitivity of 960uA ± 8% full scale positioninternal impedance :650Ω ± 10%
Insulation impedance meter outside the box plus the electrical circuit with 500V DC plus 50M ohm meter shell
Electrical insulation of the circuit impedance is 500V DC voltage test of the insulation value. Pointer to oveR Lap with the zero-scale tolerance of ± 1mm balanced meter using a standard position and tilt 90 degrees to allow the error range of ± 1mm
pointer to mount the current instant plus three times the full scale current and slowly reduced to the the electric influenza degree 1/2 readingThe pointer will return to the scale plate within 1/3 scale friction meter coupled with the current and slowly increase or decrease to a certain value indicating the point of error range of ± 1mm
brake instantly plus scale plate 2/3 of the current value of the pointer indicates the location of the time required for a second or less.

Special test:
tests on each interval of five seconds to ten times the full scale current input oveR Load the action is repeated nine times for each time of 0.5 seconds.After this test 7-14 to maintain normal.
vibration test meter packaged in the vibration plate 1000 times per minute up and down 4mm shock In each direction for 10 minutes. After this test 7-14 to maintain normal impact test meter packaged 30-cm height of fall in 3cm thick wooden board XYZ three-direction test.After this test 7-14 to maintain normal reliability test the current input of 100000 calibration points within the limits of current sense is still the standard environmental impact test temperature of 50 Celsius humidity 85% for 100 hours after this test 7-14 to maintain normal.
terminal pull test :terminals must withstand one kilogram tension sustained 60 seconds will not be affected.
