Product Description

1. Features

1. Super Safe Semiconductor Laser Driver - Current is precisely adjustable, and regardless of the working environment or even if the driver fails completely, the output will never exceed the current limit.
2. The product prevents overcurrent through multiple closed-loop controls and overcurrent protection hardware design. It uses a precision adjustable constant current feedback loop and dual closed-loop control with maximum power output limitation.
3. The overcurrent protection hardware circuit design adopts a topology structure that limits the maximum output current. Even if the hardware circuit fails, it ensures the laser is safe.
