Figure 1 shows the top view of the PLD driver and the
locations of the configuration switches, Output and Current
Limit adjust trimpots, and status LEDs.
Figure 2 shows a typical wiring diagram for the PLD driver
and external electronics to operate a Type A or B laser.
Figure 3 illustrates the three laser types that the PLD can
drive. For detailed instructions on using the different laser
types refer to the Operating Instructions on page 7 .

Use caution when the PLD is combined with a
PTC temperature controller: if the TEC or
thermistor is connected to the laser diode, two
power supplies are required and must float
independently of each other.
