Das LED PWM Controller Modul erlaubt Spannungsversorgungen von 7-30V und reguliert Ausgangsspannungen von 1,2-28V.

LED PWM Controller Modul

Die PWM Steuerung erfolgt einfach über den PWM Pin im Signalbereich von 2,8-6V.

Pinbelegung:

1. IN +: Stromversorgung positiv
2. IN-: negative Stromversorgung.
3. LED +: Spannungsversorgung LED-Anode
4. LED-: Spannungsversorgung LED-Kathode
5. PWM: PWM Signal (2,8-6V)

Bitte beachten, die Ausgangsspannung muß 2-3V unter der Eingangsspannung liegen.

The LED PWM controller module is a step down voltage converter in combination with a PWM controller.

Each of the 8 channels can be read directly by the digital I/O lines of a microcontroller unit.

The LED PWM controller module allows power supplies from 7-30V and regulates output voltages from 1.2-28V.

LED PWM Controller Module

The PWM signal control is simply done via the PWM pin with asignal range from 2.8 to 6V.

Pinout:

1. IN +: Power supply positive
2. IN-: negative power supply.
3. LED +: access the LED anode
4. LED-: then the LED cathode
5. PWM: pwm signal (2.8V-6V)

Because of buck operating output voltage must be 2-3V below input voltage.
