Striped cooling slots improve heat dissipation, reducing temperature by 10%–15% for fast diode cooling. Features high reliability, stability, anti-interference, good consistency and long service life.The laser uses an SMA connector. Flexible fiber jumpers allow free movement of the laser output end for convenient use.The laser module works with a PWM controller (sold separately). The panel supports up to 3 modules. The controller powers on automatically. Press the knob to select channels; turn left/right to adjust brightness.AssemblyApplication ExamplesEngineering DrawingsOP-20B Engineering Drawing LASER-DRV-3C_PWM Engineering Drawing
