DATASHEET AND OPERATING GUIDE
PLD10000/PLD12500
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 laser
systems around the world, proving beyond doubt the
reliability and stability of the design.
PLD Series drivers are used for fiber laser pumping,
materials
processing,
pyrotechnic
applications, and laser diode LIV testers.
DESIGNED FOR EASY INTEGRATION
The PLD10000 is powered by a 5 V supply, and the laser
can be driven from the same supply. High-compliance
lasers can be driven by using a separate supply up to 30 V.
The PLD12500 requires two separate supplies.

FEATURES AND BENEFITS
• Two models: 10 A and 12.5 A output current
• PLD10000 can be operated from a 5 VDC supply
• Separate power supply can be used to drive
• Product Variation allows high-compliance up to
• Constant Current or Constant Power modes
• Safety features protect your laser
• Remote Enable controls
• Optimized heatsink and fan simplifies integration
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; a slow
start circuit ramps the output current; and a mechanical
shorting relay protects the laser from ESD events while the
output is switched off.
Long-term reliability means better up-time, fewer service
ignition,
industrial
calls, and more customers who are satisfied with your
products.
LOWER CURRENT MODELS
The PLD Series is available in lower current models. Go
