TED200C
3 Operating Instruction
3.1 External Connections
Prior to switch on the TED200C controller, all required external connections must be made
properly. Please read the following sections carefully.
3.1.1 TEC Output
The Thorlabs TED200C controller can drive all thermoelectric coolers up to a current of 2 A.
The voltage drop across the TEC must not exceed the TED200C compliance voltage (6V)
If a Thorlabs laser mount is used, just connect the 15-pin D-SUB jack "TE OUTPUT"
of
the TED200C controller to the 9-pin plug "TEC DRIVER" of the Laser Diode Mount using the
supplied shielded cable CAB420-15.
Note
The cable should not be manipulated as it serves multiple devices and therefore does not have
the standard pin assignment as described for TED200C.
If a Thorlabs laser mount TCLDM9 or LDM21 is used, in addition the polarity of laser diode and
photodiode must be set using the two slide switches at the laser mount. Please refer to the
individual operation manual of the laser diode mount.
If other laser diode fixtures are used, connect the TE cooler and the temperature sensor using
shielded cables to "TE OUTPUT" (R5) according to the pin assignment as shown below:
