Product Overview
Material: PCB
Project Type: VU meter driver board DB audio level instrument.
Input Sensitivity: 400Hz input audio signal, 8025B digital multimeter range.
AC mV Measurement Input: 97mV, 39 level to +3dB position.
PCB Size: Approx. 63 x 52 x 20mm / 2.48 x 2.05 x 0.79in
Backlight Power Terminal: DC l0V to 12V 50MA can be used. Small bulb power backlight.
VU Meter Driver and Liquid Level Gauge Sensitivity: Recommended 500uA sensitivity, 630 Ω. The damping effect is the best at this time. The damping effect of other specifications of liquid level gauges will be different, and further adjustment is needed.
Features
1、VU Meter Driver: Designed for audio level test and integrated circuit chip, the pointer swing amplitude is moderate, and independent power supply is not required. The power supply is directly led from the original equipment.
2、Higher Accuracy: With low pass filter circuit to filter high frequency interference and provide power for harsh environment. The output sensitivity is adjustable and applicable to all kinds of headers.
3、Wide in Fitting: The most common 12VDC power supply is easy to use on on board equipment and PC computers, very practical and reliable.
4、Good Protection: With power supply reverse polarity protection. Power on pointer protection is provided for the start pointer base to extend the header life. Using 0.5W metal film resistor, large power margin, to ensure long term reliable and stable operation.
5、Easy to Install: Compact size takes up little space inside the chassis, while the light weight will largely simplify the installation.
