Product Features：
¡ Adopting high-performance CPU design, low power consumption, stable and reliable performance.
¡ Modular design, ultra small size, fewer pins, easier integration with LED driver power supply.
¡ Compliant with IEC62386 standard, with good compatibility, designed according to DALI-2 standard, any device that complies with DALI protocol can be connected to the same bus for control.
¡ Attribute type: DT6 (LED dimming), DT8 (color adjustment).
¡ PWM output effective level can be selected to adapt to various driver chips that adjust brightness by PWM, making the design more flexible.
¡ Four types of PWM output module models, suitable for various applications：
model | PWM output channel | Occupy DALI address | Notes |
CTT-DLMOD-1 | 1-channel DT6 dimming output, pin number PWM1 | 1 | PWM frequency 500H, push-pull output, maximum output current 10mA. High level=VCC; Low level=GND; The effective output is high level. |
CTT-DLMOD-2 | 2-channel DT6 dimming output, pin numbers PWM1-2 | 2 | |
CTT-DLMOD-3 | 3-channel DT6 dimming output, pin numbers PWM1-3 | 3 | |
CTT-DLMOD-4 | 4-channel DT6 dimming output, pin numbers PWM1-4 | 4 | |
CTT-DLMOD-TC | 1 channel DT8 dual color temperature output, pin numbers: cold light PWM1, warm light PWM2 | 1 | |
CTT-DLMOD-RGBW | 1 channel DT8 RGBW output, pin numbers PWM1-4 are for RGBW color respectively | 1 |
¡ Modules can be customized
¡ Suitable for LED dimming drivers with PWM dimming and color adjustment
¡ The signal interface has high voltage protection function
Electrical parameters:
Power supply: DC3.3~5.2V (voltage and current must be stable and reliable, otherwise it may cause abnormal operation of the CPU);
Pin logic level: High level=VCC, Low level=GND
PWM frequency: 500Hz, push-pull output, maximum output current of 10mA;
Dimming range: 0% (off), 1%~100% (on).
LED indicator light: When the module is working normally, the LED heartbeat flashes.
