PDD-300 is a high-power pulsed laser diode driver series. The modules are fast-switching, low-noise, accurate, and efficient current sources for laser diodes. They were developed primarily for medical and aesthetic treatments, particularly hair removal applications.

PDD-300 provides an average output power of up to 300 W and a maximum peak output power of up to 5000 W (depending on the user-defined I_max and V_max). It operates from a standard 100‑240 V AC, 50/60 Hz power supply, so no additional power supply is required. For higher output power, see PDD-1600 and PDD-1000.

Several variants of the PDD-300 are available with different maximum output voltage levels (V_max), selectable from 20 V to 50 V at the time of order. Higher output voltages are available on request. We recommend selecting V_max as close as possible to the operating voltage of your laser diodes to ensure optimal operation of the driver.

During operation, the output current can be set by the user within the range of 0 A to I_max by applying a DC voltage to the corresponding pin.

The module can also be controlled using an additional external remote control unit, LDD-RC, which is sold separately.

Since the driver was specially designed for hair removal applications, it complies with the latest versions of the applicable medical standards: IEC 60601-1:2005/AMD1:2012 for electrical safety and IEC 60601-1-2:2014 for EMC. Therefore, PDD-300 can be used in medical systems without modifications, additional filtering, or additional protective measures.

High reliability and efficiency, an easy-to-integrate OEM design, and customizable parameters for tailored solutions make the PDD-300 series one of our best-selling pulsed laser diode driver products.
