DAE-20050 is a compact and powerful laser diode driver. Current waveforms can be CW, modulated or pulsed up to 200A.
This driver includes a 32bit communication port. Commands allow the full control of the driver features (pulse generation, current level, temperature limits, pulse’s counter…) while keeping a great amount of information thanks to all the voltage, photodiode, temperatures, delayed trigger for syncs…).
DAE-20050 has been designed to support high power laser applications. An internal water circuit is bases for high demanding a Block diagram μC with an USB 2.0 signals available (current level, embedded in the applications
