How to get started
Step
What to do
Check
1
Unpack your device and place it in front
of you as shown on the next page.
2
Connect a load (for example your laser
diode) to the output.
3
Connect the RS-232 cable / PLB-21
See section “Controlling the LDP-
QCW via RS-232” for more
information.
4
Connect the input power supply. Make
sure that polarity is correct. The supply
voltage is 24 V .. 48 V.
Make sure that your
power supply does not
have any voltage overshoots when
switching on or off. Do not exceed
the maximum operating voltage of
52 V.
5
Switch the power supply on.
6
Set all required parameters using the
RS-232 interface. Make sure that the
capacitor voltage is set to a safe value.
See section “Controlling the LDP-
QCW via RS-232” for more
information.
7
Apply +5 V to the interlock pin of the
BOB connector. This will enable
internal power conditioner.
See section “Interface
Specifications” for more
information.
8
Apply +5 V to the Enable pin of the
BOB connector. This will enable the
output.
See section “Interface
Specifications” for more
information.
9
Monitor the current pulses using an
oscilloscope connected to the current
monitor output.
See section “Interface
Specifications” for more
information.
