PLDXK-CH SERIES LASER DIODE DRIVER
OPERATING INSTRUCTIONS
according to the actual application.
We recommend using a test load until you are familiar with
operation of the driver. Refer to page 3 for test load
schematics.
NECESSARY EQUIPMENT
• PLDxK-CH controller
• Digital voltmeter, 4-½ digit resolution recommended
•
• Laser diode, mount, and optional temperature control
system
• Connecting wires
•
POWER SUPPLY REQUIREMENTS
Linear-regulated or low-noise switching power supplies can
be used. We recommend using power supplies with noise
For single-supply operation, PLD5K-CH and PLD10K-CH:
• 5 VDC power supply rated for 1.1-times the maximum
laser diode current, plus 150 – 250 mA for the electronics
(see Electrical Specications
For Type C lasers with the PLD5K-CH and PLD10K-CH:
• 8 to 12 VDC power supply rated for 250 mA, plus
Figure 7 and
Figure 10
•
power supply for the laser, rated for 1.1-times the
maximum laser diode current
For two-supply operation when using the PLD5K-CH or
PLD10K-CH to drive a high-compliance laser, laser bar, or
• 5 VDC power supply rated for 250 mA for electronics
•
1.1-times the maximum laser diode drive current and
> 2 V greater than the compliance voltage of the laser
NOTE: It is critical to shut down the power supply to
the laser rst before shutting down the +5V supply
powering the electronics. Failure to follow this order
may damage the PLD or laser.

PREVENT DAMAGE FROM ELECTROSTATIC
DISCHARGE
Before proceeding, it is critical that you take precautions to
and your laser. ESD damage can result from improper
handling of sensitive electronics, and is easily preventable
with simple precautions.
Enter the search phrase “ESD Precautions for Handling
Electronics
on ESD-safe handling practices.
We recommend that you always observe ESD precautions
when handling the PLDxK-CH driver and your laser diode.
Note: The PLDxK-CH case is isolated from electrical ground.
