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 block connections

LD+ / LD-: Laser anode / cathode pins. If possible, use a short twisted cable to connect your laser. The

CTL200-0 is compatible with

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.

AI1, AI2: Auxiliary analog inputs between 0 and 2.5 V.

DO1, DO2: Digital outputs that replicate the status of LASER and TEMP LEDs on 3V3 logic levels.

DC modulation input for modulation between DC and 10 MHz. Modulation range is ±1 V. A jumper allows to

choose between 3 modulation gains.

Do you have a question about the CTL200-0 and is the answer not in the manual?

Page 1 CTL200. Terminal block connections LD+ / LD-: Laser anode / cathode pins. If possible, use a short twisted cable to connect your laser. The CTL200-0 is compatible with floating diodes. VL+ / VL-: Laser anode / cathode 4-wire voltage sensing pins.
Page 2 Adjusting the compliance voltage 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 www.koheron.com...
Page 3 CTL200-0 CTL200-0-B-600 compliance voltage Make sure to use the lowest possible compliance voltage configuration in order to minimize the power consumption. Serial interface Information related to the serial interface can be found on the CTL200 user guide. www.koheron.com 3 / 3...
