Product information "SLC-Series USB/RS232 & External Trigger LED Controllers"

2, 4 Channels; 9-24 VDC; 100-3,500 mA Per Channel; Interface USB, RS232; External Trigger; Current Resolution 0.1-1 mA

Mightex’s SLC-Series of USB/RS232 and external trigger LED controllers allow users dual software control of individual LED channels plus external TTL trigger control. User-friendly application software and SDK are provided, and models come with USB and RS232 interfaces with a flip switch on the back of the units to select either USB2.0 or RS232 interface.

Each multi-channel, computer-controllable unit comes with PC-based software with a user-friendly GUI, which enables users to drive LEDs without the need to write any code. In addition, a powerful SDK and a rich RS232 command set are provided, in order for users to write their own software and to integrate Mightex’s LED controllers into their own systems. A Linux driver is also available upon request. Furthermore, the drivers have a built-in security feature, allowing users to limit LED driving current and voltage. Models with forward voltage monitoring capability have an accuracy of ±10 mV.

Mightex’s SLC-Series of USB/RS232 and external trigger LED controllers can be used to drive any type of LED in any of the three modes ‘Normal’ (or ‘Constant Current’), ‘Strobe’, and/or external ‘Trigger’. Each output channel can be individually configured to work in one of the three modes, and in all three modes, overdrive current limit can be set:
Normal: Constant current output at any value from 0 mA to the maximum output driving current with 12-bit resolution
Trigger: External trigger signal could be used to turn on each individual channel, generating driving current with any user-defined waveform. Alternatively, each output channel can work under the “Follower” mode, in which the current output follows the waveform of the trigger input
Strobe: Internal strobe generator generates frequencies as high as 25 KHz. The strobe signal (i.e. current levels, duty cycle and strobe frequency) can be set through software. For SLC-AA and SLC-AV series, the strobe signal can be a user-defined arbitrary waveform with 128 pairs of data points [current (mA), duration (µs)] to define the shape of the waveform and consequently the LED’s optical output.

High-precision (FA, FV, XA and XV) types have 0.1mA current resolution, and a maximum current of 100mA in DC mode and 350mA in pulse mode, while 2-channel high-current (HA and HV) types can drive up to 2,000 mA (CW) or 3,500 mA (PWM) output current.
