Attention! You can customise this product to your needs.
The Tiny LDD Laser Diode Driver is an electronic device that contains high power current source (up to 10A) for laser diode (LD) and two controllers for Peltier thermoelectric coolers (TECs). Compact and highly-efficient design limits power dissipation and simplifies heat-sinking requirements. Perfectly suited for OEM applications. The Laser Diode Driver incorporates LD protection features like slow current ramp-up (soft start function), current limit, temperature limit and overheating protection.
