LD24AJTA DC 6-25V 20W Adjustable LED Driver PWM Module

LD24AJTA DC 6-25V 20W Adjustable LED Driver PWM Module

The LD24AJTA DC 6-25V 20W Adjustable LED Driver PWM Module is a compact DC-DC step-down constant-current LED driver module designed to drive high-power LEDs and LED modules with a constant current. It operates with power sources ranging from 6V to 25V DC and is particularly suitable for 6V, 9V, 12V, 18V, and 24V LED applications.

The module's output current can be adjusted between approximately 30mA and 900mA via an onboard adjustment component. This allows for the selection of the appropriate driving level for LEDs with varying current requirements.

The maximum output current can be increased to approximately 1200mA by changing the RCS current-sensing resistor on the circuit.
