LED ring lamp for studio shooting Step five: scheme
LED annular lamp for studio shooting Before installation circuits need to configure the DC/DC converter. The circuit uses an XL4015 DC-DC 5A constant current module to power the LEDs.
A power supply is required to configure the module. The master sets the output voltage on the power supply to 15 V and 4 A, then connects it to the input of the converter module. Connects the multimeter probes to the output of the converter.
Using the potentiometer on the module board, sets the voltage to 12 V, then sets the current to 2.5 amperes.
Using this module in the circuit allows you to connect any adapter from 12 to 24 V to the input. maximum current 5 Amperes.
