LDD-250 laser diode driver

The medium-power constant current laser diode driver LDD-250 is a series of devices. It was designed to provide stable current by pulses or in continuous form to laser diodes, diode bars and stacks. Pulsed laser diodes drivers are able to deliver high peak power in short durations, which is useful for applications requiring precision and minimal thermal damage, such as medical procedures and material processing.

We offer several variants of LDD-250 with different maximum output power (P_max could be 150, 250 or 400 W), maximum output current (I_max range is 5 … 100 A), maximum output voltage (V_max≤ P_max/ I_max), selected at the moment of order. For more detailed information see user manual.

Devices are in a case and easy to mount, they run on common 100‑240 V AC or 200‑240 V AC 50/60 Hz. So you don’t need any extra power supply for the driver.

An output current level can be programmed in working range by user applying a DC voltage to the respective pin. An operating frequency and pulse width are set by an external low voltage TTL signal from pulse generator. Base interface to control LDD is analogue (15 Pin “D”-Sub Female).

It is also possible to control the module through an additional external remote control assembly LDD-RC (sold separately), or through an additional external PCBs (should be purchased separately), either stand-alone (ordering code – STA) with jumpers and trimpot or driven by a computer through RS‑232 interface (ordering code – RS232).

Constant current laser diode driver module LDD-250 can be used for industrial, laboratory, and, in some cases, for medical applications. For the proven compliance to standards for a certain modification the certification procedure is need to be passed, which is available on demand.
