The maximum heat sink temperature is +85° C. When this limit is exceeded, the over-tempera- ture protection activates and switches off the TEC and LDC outputs. The controller can be switched on again only after the temperature has dropped by about 10° C. © 2018 Thorlabs GmbH...
Page 17: Connecting Laser Diode And Photo Diode
Disconnecting the laser diode during operation may destroy the laser diode! Below are shown possible configurations of the laser and monitor (photo) diode combination and the connection scheme to the output connectors ST2 or ST1. AG = Anode Grounded CG = Cathode Grounded © 2018 Thorlabs GmbH...

Page 20: Connecting Tec And Temperature Sensor
Make sure that the polarity of the TEC element (Peltier) is correct! Otherwise, the temperature will run into the wrong direction, this way leading to a thermal damage of the laser diode! Connecting a thermistor (NTC temperature sensor) Connecting an AD590 temperature sensor Connecting a LM335 temperature sensor © 2018 Thorlabs GmbH...
Page 21: Connecting The Interlock
When using the ITC1xx with Thorlabs laser diode mounts, the interlock function is provided by the mount. For details please see the Operation Manual of the used laser diode mount.
Page 22: Polarity Check Of The Tec
When the standard heat sink is used, the total output current should be limited to 3 A (I £ 3 A). Optimized cooling by fan or bigger heat sink allows 3 A LD and 3 A TEC at the same time under the condition that the power supply provides 6.1 A. © 2018 Thorlabs GmbH...

· Now remove jumper JP4 and set potentiometer P8 fully clockwise (window = infinite). · Rotate P8 slowly counter clockwise until LED3 lights up. · The ITC1xx now is running in temperature protection mode. © 2018 Thorlabs GmbH...
Page 24: Pid Adjustment
In case of a high thermal load, the adjustment ranges of the I and D shares might be insuffi- cient. The adjustment range can be increased by using additional foil capacitors: C73 for the D share and C75,C76 and C77 for the I share, typically 0.47 µF to 3.3 µF. © 2018 Thorlabs GmbH...
Page 25: Connecting Scheme Examples
Alternatively, the laser, the monitor diode, the temperature sensor, the TEC and the interlock connection can be made through the 15 pin DSUB connector ST2. This way, a Thorlabs laser diode mount can be connected directly using the CAB430 cable (to be ordered separately).

For warranty repairs or service the unit must be sent back to Thorlabs GmbH. The customer will carry the shipping costs to Thorlabs GmbH, in case of warranty repairs Thorlabs GmbH will carry the shipping costs back to the customer.
Page 43: Copyright And Exclusion Of Reliability
As the WEEE directive applies to self contained operational electrical and electronic products, this “end of life” take back service does not refer to other Thorlabs GmbH products, such as · pure OEM products, that means assemblies to be built into a unit by the user (e. g. OEM laser driver cards) ·...
