Listed at 18.38 USD. TN90VU Meter DB Level Header Audio Power Amplifier Chassis with Backlight Description:Pointer material: zinc and copper-nickel alloy.Pointer color: redThe direction of pointer swing: from left to rightPointer length: 44 ± 1 mm from the center axis to the end of the needlePointer width: 0.45 ± 0.05 mm Electrical characteristics:Standard test conditions temperature: 20 ° C, humidity 70%. Can also be tested under normal temperature and humidity conditions.The influenza degree pointer on the zero scale to the maximum scale sensitivity of 960uA ± 8% (full scale position).Internal impedance: 650Ω ± 10%.Insulation impedance meter outside the box plus the electrical circuit with 500V DC plus 50M ohm meter shell.The electrical circuit impedance insulation is 500V DC test of the insulation value. Pointer overlaps with the zero scale tolerance of ± 1 mm of the symmetrical meter using a standard position and 90 ° inclination to allow the error range of ± 1 mmPointer to mount the current time plus three times the full scale current, and slowly reduced to the electrical influenza grade 1/2 reading,Pointer returns to the scale plate within a friction meter of 1/3 coupled with the current, and slowly increases or decreases to a certain value, indicating the error range of ± 1 mm.Brake immediately plus scale plate 2/3 of the current value of the pointer indicates the position of the time required for one second or less. Special test:Tests in each interval of five seconds to ten times the full overload of the current input, the action is repeated nine times for each time of 0.5 seconds. After this test 7-14 to remain normal.Vibration meter packed in the vibration plate 1,000 times per minute, up and down 4mm shock in each direction for 10 minutes. After this test 7-14 to normal impact test meter packed packed 30-cm height of the fall into 3cm thick wooden board, XYZ three-directional test.After this test 7-14 to maintain the normal reliability test of the current input of 100,000 calibration points within the limits of the current sense is still the standard environmental compatibility test temperature of 50 ° C, humidity 85%, for 100 hours, after this test 7-14 to maintain normal.Terminal pull test: terminals must withstand one kilogram of tension, sustained 60 seconds will not be affected. Other:Temperature limits for use: -10 ° C to +60 ° C RH 35 to 85%.Temperature limits for storage: -20 ° C to +60 ° C RH 35 to 85%. ----- Do not use the meter in direct sunlight and place the meter in the box to avoid foreign objects inside the meter.Soldering condition terminal placed about 3 mm in the temperature of 230 ° C tinplate 3.5 seconds.After this test, 7-14 to hold normal,Hand soldering gun to soldering temperature 350 ° C, the terminal contact for 3.5 seconds, the terminal front end of about 3 mm contact with the soldering gun.After this test, 7-14 to hold normal,Anti-static test in the same direction three times to mark the difference between the pointer in the length of the scale in a transparent cover surface to dry nylon 1/3 back to the zero position.Bulb specifications: weak yellow neon bulb 12V.We have TA-7318P original VU meter driver board for this VU meter in stock. Package:1pc VU meter level audio power amplifier chassis backlight. Payment Method: PayPal preferred Shippment:We provide free shipping to international via China Post Airmail.
