P65 constant current module is a module used to provide constant current, typically used in power systems, lighting systems, or other applications that require constant current.

The IP65 constant current module is a constant current source module that can provide a constant current composed of the module's input resistance and internal diodes. IP65 constant current modules typically consist of a chip, an input resistor, and a diode. A chip is usually a microcontroller, with an input resistor used to limit the input current and a diode used to provide a constant current.

The working principle of the IP65 constant current module is to generate a constant current in the circuit between the input resistor and the diode. The input resistor limits the input current and converts it into a voltage signal, which is transmitted to the internal diode. The internal diode provides a constant current through the potential difference between the positive and negative electrodes, which is supplied by the module's power supply.

It should be noted that the use of IP65 constant current modules requires caution as they may have a negative impact on the performance of the device. When using, it is necessary to follow the equipment's operating manual or other instructions to ensure the normal operation of the equipment.
