Product information "PLD Series Laser Diode Drivers"

Output Current LD 0.2-12.5 A; PCB Mount; Compatible with Type A, B & C Lasers

Wavelength Electronics’ PLD series of component type laser diode drivers deliver reliability and performance in a compact and easy-to-integrate SIP or DIP package. Tens of thousands of PLD laser diode drivers are deployed in laser systems around the world, proving beyond doubt the reliability and stability of the design. With the CE certified PLD series you can optimize your total system performance as Wavelength Electronics offers the PLD Series drivers over a range of output currents. Choose the model that best suits your needs or contact AMS Technologies if you need assistance deciding.

Within the PLD series with SIP or DIP circuit-board mounted package, output ranges of 0.2, 0.5, 1.25, 5, 6.5, 10 and 12.5 A are available. For chassis mounted variants please refer to Wavelength Electronics’ PLDxK-CH series of laser diode drivers.

The PLD drivers operate from a single 5 V power supply. To accommodate high compliance lasers, or multiple stacked lasers, the PLD laser diode drivers allow the laser to be driven from a separate power supply up to 30 V. The PLD12500 requires two separate supplies.

The available PLDEVALPCB evaluation circuit board reduces your development costs and allows you to focus on designing the features that will set your system apart. Remote computer control is available using the USBKIT, which also allows graphing and datalogging.

Thoughtfully designed features provide valuable benefits and protect the laser against operational anomalies. Remote enable can be tied to a safety interlock and a temperature controller, such as Wavelength’s PTC series. Built-in constant current and constant power operating modes minimize your electronics overhead. On-board controls mean quick and easy driver setup. Analog setpoint input gives you remote external control of the laser current and modulation. Latching current limit safely switches off output if current limit is reached.

Built-in safety features make your product more robust to real world operating conditions: latching current limit, slow start circuit, and a mechanical shorting relay protect the laser and ensure long-term system reliability.
