• Local and Remote Power-On and Enable controls
• Integral heatsink and fan on high current models
RELIABILITY YOU CAN TRUST
The PLD Series Laser Diode Drivers deliver the reliability and
performance you expect from a Wavelength Electronics laser
driver in a compact and easy-to-integrate package. Tens of
thousands of PLD drivers are deployed in particle counters,
manufacturing vision systems, wavefront scanners, fiber
aligners, and other laser systems around the world, proving
beyond doubt the reliability and stability of the design.
DESIGNED FOR EASY INTEGRATION
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.
LASER SAFETY FEATURES
Built-in safety features make your product more robust
to real world operating conditions: latching current limit
switches off the output if the current limit is reached; slow
start circuit ramps the output current; and a mechanical
shorting relay protects the laser from ESD events.
Long‑term reliability means better up-time, fewer service
calls, and more customers who are satisfied with your
products.
HIGH OUTPUT CURRENT
The PLD Series is available up to 12.5 A drive current.
