On this page you can see a series of laser diode drivers for power supply of high power laser diodes, laser diode lines, and diode lasers.

Maximal output power is 600, 1000 or 1500 W. Various current/voltage ratios are available. Maximal output current up to 100 A. For more information see user manual.

Diode driver characteristics meet the latest versions of medical standards requirements: IEC 60601 for electrical safety, IEC 61000-3-2 for active power factor correction (PFC) and EN 55011 / CISPR 11 Class A safety requirements for EMI and leakage current.

So modules may be used in different kinds of medical devices without any additional filtration and safety measures.

We offer diode driver in several modifications with different maximum output currents and voltages.

First of all user should choose maximal output power (600, 1000 or 1500 W). Then maximal output current in the range of 10 ... 100 A should be selected. Maximal output voltage is obtained automatically as Wmax / Imax.
