CTL200-0 User Guide
Note
This guide describes the information that is specific to the screw terminal version of the CTL200. Please refer to
the
CTL200 user guide
for general information on the CTL200.
Terminal connections
LD+ / LD-: Laser anode / cathode pins. If possible, use a short twisted cable to connect your laser. The
CTL200-0 is only compatible with floating diodes, which means that neither the anode nor the cathode
should be electrically connected to GND.
VL+ / VL-: Laser anode / cathode 4-wire voltage sensing pins.
PD+ / PD-: Photodiode anode / cathode pins. PD+ is internally connected to GND.
TH+ / TH-: 10K thermistor pins.
TEC+ / TEC-: Connections to the Peltier element.
Power supply
The board must be supplied at the VS pin with a voltage between 7.5 V and 12.5 V.

- Page 2 The switches SW3 and SW4 of the configuration switch are used to adjust the compliance voltage. The figure below shows the maximum laser voltage vs. current for the 4 compliance voltage configurations. CTL200-0-B-200 compliance voltage CTL200-0-B-400 compliance voltage CTL200-0-B-600 compliance voltage Make sure to use the lowest possible compliance voltage configuration in order to minimize the power consumption.
