The PLD5K-CH is a 5 A Laser Diode Driver in a small chassis mount package. Operating from a single +5 V supply minimizes internal heat dissipation. Modular packaging makes it easy to integrate the PLD into your system. For applications that require a higher forward voltage, a separate laser diode power supply input lets you provide a higher compliance voltage.
These drivers are not recommended for low noise applications. See the LD5CHA, LD10CHA, or LD15CHA for lower noise laser drivers.
PRACTICAL FEATURES FOR REAL-WORLD CONDITIONS
The Active Current Limit not only protects your laser diode, but ensures that you are operating with maximum stability. When the laser current reaches the level set by the Limit I Trimpot, the output disables and the Limit LED and Limit Status indicate the current limit has been reached. For 12.5 A or 10 A select the PLD12.5K-CH or PLD10K-CH, respectively. For 6.5 A or 5 A in a PCB mount package, select the PLD6500 or PLD5000, respectively.
VERSATILE AND EASY TO USE
Two photodiode ranges provide variable sensitivities for optimum operation. You can maintain excellent stability when operating in both Constant Current and Constant Power mode. All trimpots and switches are easily accessible and offer precision control. A slow start circuit, mechanical shorting relay, and Active Current Limit offer maximum protection for your laser diode even when power is removed.
The PLD5K-CH includes user adjustments and status indicators. Onboard trimpots set current limit and current setpoint. Alternately, you can use the modulation / remote input for laser driver current setpoint. An LED indicates status of the laser diode output current. Another LED indicates when the current limit trip point has been triggered. Switches select Constant Current or Constant Power mode and photodiode range.
The PLD chassis mount laser diode drivers have a matching temperature controller family. The PTC10K-CH , PTC5K-CH and PTC2.5K‑CH drive 10 A, 5 A, and 2.5 A of temperature controller current respectively. Up to 20 A can be delivered using the PTC10K-SL current booster.
Remote computer control is available using the USBKIT, which also allows graphing and datalogging.
The LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the PLD-CH and the laser.
This product is ideal for applications where current stability is critical and space is tight, such as benchtop inspection instruments, optofluidics and surgical laser control. It is CE certified. A PDF version of the Declaration of Conformance is available.
