PICOLAS LDP-CWL 06-20, User Manual, Page: 7 / 19

7
the LDP-CWL is in the “modulation
mode”.
9 Monitoring of the output current.
On current monitor you can
measure a signal comparable
with the input signal. Use an
oscilloscope with a 1 MEG ohm
termination.
Scale 3 A/V .
(example:
4 V at current monitor read means 12 A
at the output)
10 Disable the input signal and turn off
the power source. Remove the test
diode or bypass and assemble the
final laser diode.
11 Turn the power supply for the V
cc
back on.
Range of Vcc 15 V .. 48 V.
Minimum
10 V above compliance voltage.
12 Feed a signal to the input terminal.
Make sure not to overload the
laser diode!
*Important: Please refer to the position of the jumper as in the Picture 4, the
printing on the board may be different. However, it does not have any impact
on the functionality of the driver itself.

Required Laser Diode Pin Out
The LDP-CWL 06-20 / LDP-CWL 12-20 is designed for the direct connection of
almost any kind of laser diode with a maximum compliance voltage of 20 V.
The pitch of the LD- and LD+ connectors is 15.5 mm.
