3.2. Uhlan PowerLed V1.0 SMD 1A
Regulator PWM current control with LED power LEDs for plant automation based on integrated circuit switched. This circuit is characterized by the ability to program the output current of the LED in 100mA steps up to 1A, a wide range in the operating voltage that allows the regulator to work between 6 and 60V, allowing up to 4 placed in series LED lamps LEDs. Working at a high frequency 500KHz allows you to use small components significantly reduced the extent of PCB and obtaining a very high yield, up to 95%.
