Note：
1. The maximum output voltage is 0.5V 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-0.5V=23.5V.
2. Each output channel can be individually configured to operate in one of the following three (3) modes and controlled through PC software with GUI. In all three modes, an overcurrent limit can be set:
Normal: Output a constant current at any value between 0mA and 1000mA with a 12 bit resolution.
Trigger: External trigger signals can be used to open each individual channel, generating driving currents with any user-defined waveform. Alternatively, each output channel can operate in "follower" mode, where the current output follows the waveform of the trigger input;
Strobe: The internal strobe generator generates a frequency of up to 25KHz. The strobe signal (i.e. current level, duty cycle, and strobe frequency) can be set through software. For the AA and AV series, the strobe signal can be any user-defined waveform with 128 data points.
3. Any waveform. Using the accompanying application software or SDK or RS232 command set, users can define any arbitrary waveform using 128 data points.
4. Adequate heat dissipation should be provided for the LED controller in the customer's system to prevent overheating, which may cause the LED controller to shut down on its own for protection purposes. In addition, the total output current of all channels should not exceed the capacity of the power adapter.
5. It is not recommended to install A/J type LED and B type LED mixed on a single unit of this controller. Please run A/J type LED on one unit and B type LED on another unit.

What is“arbitrary waveform”？
For certain LED controller models, up to 128 pairs of [current (mA), duration (μ s)] data points can be used to define the "shape" of the waveform. This will allow the definition of "arbitrary waveform" for LED driving current, thereby defining the light output of the LED. Please refer to the following figure for details.
