3AM PP24V12W series has a simple knob control and PWM pulse output. Each channel can provide 12 Watt of power. The brightness of lighting source is adjusted by a knob. External control can be used by DC5-24V. Based on the number of lighting used, 1, 2, 4 channels models can be selected.

1.PWM pulse output. Adjust the knob to change output value of voltage frequency.
2. Each channel is 12W.
3.Input voltage is AC100V~AC240V.
4.According to LED quantity to choose 1CH/ 2CH/ 4CH models.
5.Use the external control, it can be driven by DC5~24V.
