Linear Laser Diode Drivers
Sep 2011Wavelength Electronics Inc.Request Info
Wavelength Electronics Inc.’s PLD-CH chassis mount series
is available in a 12.5-A model, the PLD12.5K-CH. This compact linear laser diode
driver supports the fiber-coupled lasers used in applications such as medical, dental,
micromachining, materials processing, imaging and semiconductor inspection. The
PLD-CH series offers low-voltage operation from a 5-VDC supply, which minimizes
heat dissipation. For applications that require a higher forward voltage, a separate
laser diode power supply input allows for flexible compliance voltages up to 28
VDC. Safety features include a slow start circuit, a mechanical shorting relay and
active current limit, offering protection for the laser diode, even when power is
removed. The active current limit ensures that it is operating with maximum stability.
Two photodiode ranges provide variable sensitivities for optimum performance.
