Explanation:

"DC Input” defines the voltage range, you can operate the laser diode driver with. All laser drivers with DC Input range higher of at least 48 V can directly be operated with industrial power supplies. The more output current and more output voltage provided, the higher the output power. Therefore, our LDD-1137 and LDD-1303 are high-power laser drivers, the LDD-1321 is a low-power laser driver. Column “Operation Mode” gives you an idea about the applications you can use the laser diode drivers for. The column "Communication Interfaces" shows you which interfaces you can use to integrate our devices into your laser system. More detailed values of each device you can get by clicking on the device’s name.
