QR code bus card reader with wide voltage design

Many customers consulted the QR code bus card machine power supply questions. This article systematically introduces the detailed description of the power supply for QR code bus card machine independently developed by Shenzhen Cardlan Tech. If you do not understand, you can consult online customer service or call us.

   

Due to the high frequency of power use of the QR code bus card machine, the startup is frequent, and the generator is in full load when the bus is running normally, and the voltage and current output instantaneously are large. To ensure that the QR code bus card machine is in normal working condition, the power supply for the bus code scanning card machine is very high:

   1. Without separate power supply, must be integrated in the bus card  machine, support wide voltage input (DC 7-41V), can meet the power supply requirements of gasoline and diesel vehicles and trams;

2. Strong anti-interference ability and strong shielding measures;

3. Regardless of the positive or negative function, whether it is connected or reversed, it can be used normally, and will not affect the normal switching machine of the card reader. (Most of the bus companies do not understand the circuit on the car, so the connection without the positive and negative poles can guarantee Installation efficiency, and can prevent the situation of burning equipment due to the reverse connection of the positive and negative electrodes).

Shenzhen Cardlan bus card machine supports mobile QR code payment, working by bus power supply, bus card machine and power supply two in one, no independent power supply. Independent intellectual property power supply with wide voltage design, can meet different domestic and international steam car environment, directly connect to bus supply, regardless of the positive and negative poles, no worry about the wrong line leading to the terminal burnout, with GPS positioning, can do automatic station report and number statistics, segmentation charges, etc., remote automatic upgrade firmware, save technical staff expenses .
