Getting Started
3.3 Electrical Installation
3.3.1 Rear Panel Connector Identification
Fig. 3.2 Rear Panel Connections
TEC OUTPUT
(15-Pin D-Sub connector) – Provides connection to the Laser Diode
Mount or other device. If Laser Diode Mounts by Thorlabs are used, connect the
"TEC OUTPUT" of the TTC001 to the 9-pin plug "TEC DRIVER" of the Laser Diode
Mount, using the provided shielded cable CAB420-15.
With other equ ipment, connect the TEC element and the temperature sensor as
detailed in Appendix A.1
TUNE IN
– Used to control the output of the controller from an external source. A zero
to 5 V analog input can be used to either adjust the set temperature, allowing the PID
loop to maintain the desired temperature, or it can be used to directly control the
current output of the controller.
When used to adjust the set temperature, the maximum tuning range for the analog
control input "TUNE IN" is detailed in Section 4.3.9.
When directly controlling the current output, the current limit (iLim) is used to scale the
analog input so that the 0 to 5 V provides a range of ±iLim - Section 4.3.4.
3.3.2 Connecting The TEC Element and Temperature Sensor
If Laser Diode Mounts by Thorlabs are used, connect the "TEC OUTPUT" of the
TTC001 to the 9 -pin plug "TEC DRIVER" of th e Laser Diode Mount, using the
provided shielded cable CAB420-15.
The unit can also be used with any standard thermistor or AD590/AD592 temperature
sensors. Connect the TEC element and the temperature sensor as detailed in the
following sections.
For thermistors, a measurement range of 0 and 20.00 k
Ω
(TH20) or 0 and 200.0 k
Ω
(TH200) can be selected - see Section 4.3.3. When AD590 (also AD592) temperature
sensors are connected, the measurement range is between -45.0 °C and +125.0 °C.
