Kqcibz Driver Board P-134 VU Meter Drive Board VU Meter Audio Backlight Analog Digital Power Meter, Black & Blue, 500007415

Description

• VU Meter Features: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 1000 10% (full scale position);Internal impedance :800 ohm 10%;Insulation impedance meter outside the the electrical circuit with 500V DC plus 50M ohm meter
• The pointer 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.
• VU Meter Special Test:Tests on each interval of five seconds to ten times the full scale current input overload, 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 1,000 times per minute, up and down 4mm shock In each direction for 10 minutes.
• Electrical insulation of the circuit impedance is 500V test of the insulation value. Pointer to overlap 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 reading,
• After this test 7-14 to maintain normal impact test meter packaged 30-cm height of fall in 3cm thick wooden board, three-direction test.After this test, 7-14 to maintain normal reliability test the current input of 100,000 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.

Kqcibz Terminal pull test: terminals must withstand one kilogram tension, sustained 60 seconds not be affected. VU Meter Others: Using the temperature limits: -10 Celsius to +60 Celsius 35 to 85% Storage temperature limits: -20 Celsius to +60 Celsius 35 to 85% Do not use the meter in direct sunlight, and PUT the meter in to avoid foreign matter into the meter internal. Soldering Condition terminal about 3 mm placed in the temperature of 230 Celsius tin plate, placed 3.5 seconds. After this test, 7-14 to maintain normal, Hand-held soldering to solder temperature 350 Celsius, the terminal for 3.5 seconds, the terminal front-end of about 3mm with the solder . After this test, 7-14 to maintain normal, Anti-static test in the same direction three times, to characterize the difference between the pointer in the length of the scale in a transparent cover to dry nylon 1/3 back to the zero position. Bulb size: 4 LED backlighting, parallel to the PCB (3.0-3.2V 80mA)VU Meter The direction of the pointer swing: left to right Pointer length: 70 1 mm from the center to the needle end Pointer width: 0.45 0.05 mm Colour:Black + Material:Zinc cupronickel Size:13.4x9.5x4.5cm Package Contents: 1 x VU level meter
