1. VU Meter Driver: Designed for audio level testing and integrated circuit chip, the pointer is moderate amplitude, no independent power supply is required. Power source is directed directly from original equipment
2.Higher Precision: It has a low pass filter circuit to filter high frequency interference and supply power in harsh environments. The output sensitivity is adjustable and can be applied to any type of header.
3. Wide Compatibility: The most common 12VDC power supply is easy to use in car devices and PC computers, very practical and reliable.
4. Excellent Protection: Power reverse polarity protection function. Power-on pointer protection is provided to the start pointer base to extend the life of the header. Using 0.5W metal film resistor to ensure a large power margin and reliable and stable operation for a long time.
5.Easy to install: Compact size takes up little space in the chassis and lightweight makes installation much simpler.
