SPAV, 20mA Mini Miniature Constant Current Source for LEDs

This "smart resistor" always supplies your LEDs with the correct current, even with AC voltage.

The electronics limit the current to approximately 20mA, regardless of the supply voltage. Your LED will always glow constantly in a voltage range between 4V and 24V.

Depending on the LED type and input voltage, 11 LEDs can be connected in series. Parallel connection is also possible, in which case the current is divided among the LEDs.

The constant current source has two connection pads to which a DC or AC voltage is connected, and two additional pads serve as the + and - outputs.A buffer capacitor can also be connected via the connection pad on the bridge rectifier, for example, to install flicker-free train lighting.

All connection pads are wired, making installation easy.
