High-Current Universal 2-Channel LED Controllers with External Triggers and up to 2,000mA (CW) & 3,500mA (PWM) Output Current


Mightex has developed a series of computer-controllable, multi-channel, universal LED drivers, which can be used to drive any type of LED in any of the three (3) modes: ‘NORMAL’ (or ‘constant current’), ‘STROBE’, and/or external ‘TRIGGER’ mode. Each 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 is provided, in order for users to write their own software and to integrate Mightex’s LED drivers into their own systems. Furthermore, the drivers have a built-in security feature, allowing users to limit LED driving current and voltage.

This datasheet covers two (2) product series (i.e. HA and HV series) of High-Precision Universal 2-Channel LED Controllers with External Triggers and up to 2,000mA (CW) & 3,500mA (PWM) Output Current.
