This circuit enables the operation of LEDs with an input voltage of 4 - 30 V DC without an additional series resistor. The LED can therefore run on variable voltage with largely constant brightness. Several LEDs can be connected in series. - Operating voltage: 4 - 30 V DC - Constant current: approx. 10 mA - Dimensions: 10 x 7 mm https://elecena.pl/product/18271603/118-5027-led-constant-current-source 2021-05-02 https://elecena.pl/product/18271603/118-5027-led-constant-current-source 2021-12-12 https://elecena.pl/product/18271603/118-5027-led-constant-current-source 2022-10-15 https://elecena.pl/product/18271603/118-5027-led-constant-current-source 2025-02-08
