Product specifications and parameters
Product manual:
Parameter | SLC-XAxx-xx | SLC-XVxx-xx | SLC-FAxx-xx | SLC-FVxx-xx | Unit |
Power input voltage,V dc | 9~24 | V |
Power input current | < 4,000 | mA |
Drive voltage for each channel(maximum)1 | (Vdc - 0.5) | V |
Drive current for each channel | 0 ~ 100(“Normal”mode) | mA |
0 ~ 350(“Flashing” or“Trigger” Mode) | mA |
Output current resolution | 0.1 | mA |
Linearity of output current | +/-0.4(or +/-0.5%) | mA |
Repeatability of output current | +/-0.1(or +/-0.2%) | mA |
Trigger input high level | 4.5 ~ 10.0 | V |
Trigger input low level | 0.8(maximum) | V |
Forward voltage monitoring accuracy | Not Applicable | +/-10 | Not Applicable | +/-10 | mV |
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 100mA 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 can generate 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 waveform using 128 data points.
Time sequence specification:

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.
