1. The maximum output voltage is 3V lower than the input voltage of the power supply. For example, if the input voltage of the power supply is Vdc=24V, the maximum output voltage Vmax is Vdc-3V=21V;
2、If the channel output voltage is Vd and the output current is Id, then they must simultaneously satisfy：（1）Vd <= Vmax ；（2）Id <= Imax；（3）Vd * Id <= Pmax；
3. Each cycle of PWM square wave consists of an on time and an off time, which are two (2) "steps". The minimum value for each step is 1000 μ s, and the minimum increment is 100 μ s;
4. Adequate heat dissipation should be provided for the LED controller in the customer's system to prevent overheating and self protective shutdown of the LED controller. In addition, the total output current of all channels should not exceed the capacity of the power adapter.
