The portable handheld laser currency detector is a renminbi banknote discriminator whose appearance is about the size of a mobile phone. Its appearance requires a short, small, light, thin and user-friendly design concept. In terms of functions, it requires diversified functions, high accuracy and energy-saving characteristics. Therefore, a truly portable handheld laser currency detector should be an electronic product with good stability and high technological content.
The portable handheld laser currency detector is small in appearance and beautiful in appearance. The inspection function is mainly based on laser technology, supplemented by infrared and fluorescent inspection. External 4.5～12VDC-AC power supply non-polarity input port. It can be more convenient to use an external power supply. When using an external power supply, the internal circuit automatically performs internal and external power conversion without worrying about the safety and energy loss of the internal battery. In addition, this product is equipped with internal battery reverse protection; internal and external power supply overvoltage (15V), undervoltage (3.5V) and load overcurrent (800mA), short circuit protection functions. After the protection function is activated, the power supply is completely shut off to protect the power supply and prevent further damage to the instrument.
