1 General Information

1 General Information

The Thorlabs TED200C Thermoelectric Temperature Controller is a precise temperature
controller for laser diodes and detectors.

The TED200C is excellently suited for:

· wavelength stabilization of laser diodes

· noise reduction of detectors

· laser diode's wavelength tuning by regulating the temperature

· modulation of wavelength by tuning the temperature

The TED200C is easy to operate via the operating elements on the front panel. Operating
parameters are shown on a 5-digit LED display. UP-DOWN keys allow to select the parameter
to be displayed.

The P, I and D shares of the temperature control loop can be set independent of each other.
The TED200C operates with different temperature sensors - NTC thermistors and IC

temperature sensors are supported. With a thermistor, the temperature is displayed in kW, with
a temperature sensor IC - in °C.

The output for the TEC current can be switched on or off via front panel key.
The temperature sensor and the TEC element are connected to a 15-pin D-SUB jack at the

rear of the unit.
At the TE OUTPUT jack a control signal is available to drive an external LED to indicate TEC

ON mode when the TEC current is activated.
The set value of the temperature can be changed with a knob at the front panel or via an

analog input at the rear panel.
For monitoring purposes, an DC voltage proportional to the actual temperature is available at

the rear panel (CTL OUT).
The TED200C controller is cooled by an internal fan, which protects the unit against

overheating in case of high environmental temperatures. With free air circulation a safe
operation of the unit is guaranteed up to 40 °C ambient temperature.

Warning

Do not obstruct the air ventilation slots in the housing!

Note

In order to prevent damages to the laser diode, it is recommended to mount the laser into a
suitable Thorlabs laser diode mount (e.g., LM14S2, LDM21 or TCLDM9) and connect it to the
TED200C using the supplied Thorlabs CAB420-15 cable. This ensures the utmost protection of
the laser diode from damage by wrong connection.

In case of overheating, the output is switched off automatically in order to avoid damages. The
LED "OTP" (Overtemperature Protection) indicates the overtemperature. After a temperature
drop for about 10°C the LED "OTP" extinguishes and the output current can be switched on
again by pressing the key "ON".

If an error occurs (OTP or OPEN) the corresponding LED lights up and a short warning beep is
heard.

The installed mains filter and the careful shielding of the transformer provide a low ripple at the
output.

1.1 Protection of the TEC element

· Limit of the TEC current in all operating modes

Protection against thermal destruction.

· Protection of the sensor

Protection against use of incorrect temperature sensors; protection against interrupted
connection of the temperature sensor.

· Contact protection of the TEC element (open circuit)

Protection against cable damage, bad contact or TEC element with too high resistance.

· Control LED for TEC current on

Protection against accidental turning off the cooling.

· Overtemperature protection

Protection against malfunction caused by internal overheating of the controller.

· Line failure protection

The TEC current is switched off immediately if a power failure or line interruption occurs. In
this case, same as after turning on the controller, the TEC current remains switched off and
can be switched on manually only.

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" (R5) 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:

3 Operating Instruction

3.1.2 Connecting the TEC element

Connect the thermoelectric cooler between pin 5, 6, 7 (TEC anode) and pin 13, 14, 15 (TEC
cathode) of the 15-pin D-SUB jack .

Attention

A mispoled TEC element may lead to thermal runaway and destruction of the connected
components.

Check the TEC polarity

· Turn on the Temperature Controller TED200C

· Connect the temperature sensor to the jack "TE OUTPUT" (R5)

(refer to "Connecting a temperature sensor ").

· Select the appropriate sensor type with the key (F25).

· Select a suitable current limit "ILIM" for the TEC element

(refer to “Setting the TEC current limit ").

· Switch the display to "TSET" and set the desired set temperature using the tuning knob.

· By pressing the key "ON" switch on the TED200C outpu t current. The LED "ON" (F8)

lights up.

· Switch the LED display to "TACT".

10

12

15

If the TEC module is connected with correct polarity, the difference between the set
temperature "TSET" and the actual temperature "TACT" will decrease. If the control loop
parameters are set well (see section Adjusting Temperature Control Loop ), the actual

16

temperature approximates the set temperature within a short time.
If the TEC module is connected with wrong polarity, the difference between set temperature

and actual temperature will increase continuously. Switch off the TEC current by pressing key
"ON" (F9) and change the TEC module wiring at the D-SUB plug connected to the jack “TE
OUTPUT” (R5).

3.1.3 Control LED for TEC ON mode

If a LED is connected between pin 1 and pin 8 as shown to the
left, this LED lights up when the TEC current output is switched
on.

TED200C

3.1.4 Connecting a temperature sensor

The TED200C is compatible with a number of temperature sensor types:

· NTC (standard thermistor)

· AD590/AD592

· LM135/LM335

The temperature sensor is selected at the front ( key SENSOR - F25 ). The LED F19 to F21

8

indicate the selected sensor.

Temperature Ranges

· NTC (thermistor): 2 measu re ment ranges - 0 to 20kW and 0 to 2 00kW

· AD590/AD592/LM135/LM335): the measurement range -45°C to +145°C.

· The actual temperature control range depends on the sensor ratings and the individual

thermal setup.

If no temperature sensor is connected or if the temperature sensor does not correspond to the
selected sensor type, the LED “OPEN” (F6) lights up and the display (F1) indicates overflow
when "TACT" measurement value is selected.

The temperature sensor is connected to the 15-pin D-SUB jack "TE OUTPUT" (R5) at the rear
of the TED200C depending on the used sensor type.

Note

If LM135/LM335 is used as temperature sensor, select "AD590" (key F25). The LED
"AD590" (F19) lights up.

Thermistor

A thermistor is a resistor with a Negative Temperature Characteristic, that's why it is also known
as NTC. It's resistance decreases exponentially with the temperature.

A thermistor must be connected between pin 3 and pin 4 of the 15-pin D-SUB

jack (R5) . The polarity is not relevant, so far the thermistor is floating. If one

10

pin of the thermistor is grounded (for example in a laser module), this pin has to
be connected to pin3.

If the TED200C is operated with a thermistor temperature sensor, the "TSET"
and "TACT" temperature is displayed as resistance in kW.

The NTC measurement current is 100µA in 20kW range and 10µA in 200kW
range.

To describe the dependency of resistance vs. temperature, several algorithms
are known. A simplified method, giving good results within a range relatively close to the
reference temperature, is the exponential formula:

the thermistor characteristic R(T) is given in the data sheet, the thermistor resistance can be
read directly. Then select "TSET" (key F18 or F19) to display the resistance set value. Adjust the
value using the tuning knob (F10).

AD 590/AD 592 Temperature sensor

AD590/592 are IC transducer type temperature sensors that
produce an output current linearly proportional to the absolute
temperature.

These devices act as current source, delivering 1µA/K within a
wide supply voltage range. They are calibrated to 298.2µA output
current at 298.2K (25°C).

An AD590/592 is connected between pin 10 (-) and pin 11 (+) of
the 15-pin D-SUB jack "TE OUTPUT" (R5)

The accuracy of the displayed temperature depends on the

tolerance of the used transducer.

LM135/LM335 Temperature sensor

The LMx35 Temperature Transducer Sensors operate as a zener
diode (inverse current direction) with a breakdown voltage linearly
proportional to absolute temperature at +10 mV/K. They operate
over a current range of 400 µ A to 5 mA.

A LM135/LM335 is connected to pin 10 (+), pin 11 (also +) and pin
8 (AGND) of the 15-pin D-SUB jack "TE OUTPUT" (R5) at the rear
of the unit.

The accuracy of the displayed temperature depends on the
tolerance of the used transducer.

3.1.5 Analog Temperature Tuning Input

The set temperature "TSET" can be tuned by applying a voltage to the input "TUNE IN" (R1) at
the rear panel of the TED200C. The temperature set value is proportional to the sum of the
signal at input "TUNE IN" (R1) and of the value set with the adjustment knob (F10).

The tuning range for the analog control input "TUNE IN" depends on the connected sensor:

Note

Only slow variations of the temperature set value (<< 1 Hz) are possible via the analog control
input "TUNE IN".

The actual temperature "TACT"can be observed at the temperature monitor output "CTL
OUT" (R2).

3.1.6 Analog Temperature Output

The analog output "CTL OUT" (R2) delivers a DC voltage, proportional to the actual
temperature "TACT". The output voltage range depends on the used temperature sensor:

To the analog output "CTL OUT" any measurement equipment can be connected directly.
Devices connected to these outputs should have an input resistance of 10 kW.

This monitor output is convenient to use for temperature monitoring e.g. during adjustment of
PID loop parameters.

3.2 Operation

· Connect the jack "TE OUTPUT" (R5) at the rear panel of the TED200C to the input "TEC
DRIVER" of the Thorlabs Laser Diode Mount using the supplied cable CAB420-15. If a
different laser diode fixtures is used, the output jack “TE OUTPUT” (R5) must be connected
according to the TEC Output pin assignment , see also "Connecting a temperature sensor”

12

.

· Switch on the Temperature Controller TED200C.

10

· Select a suitable current limit "I LIM " for the TEC element

15 15 15

· Select the used temperature sensor with key (F25).

Note

The TEC output can be switched on only if a temperature sensor is connected "TE
OUTPUT" (R5) and the sensor type is selected correctly. If the connected temperature sensor
does not correspond to the selected sensor type, the LED "OPEN" (F6) lights up. In this case
check the connection and the type of the temperature sensor.

· Select "TSET" to display the set temperature (keys F17 or F18)

· Set the desired temperature "TSET" using the tuning knob (F10).

· If a thermistor is used, the instead of temperature (°C) the resistance is set (kW). If an

AD590/AD592 or LM135/LM335 is used as temperature sensor, the set temperature is
entered in °C.

· Switch on the TEC current output by pressing key "ON" (F9). The LED "ON" (F8) lights up.

Note

The TEC output cannot be switched on as long as the LED "OPEN" (F6) lights up. In such case
check the connection of the temperature sensor and the selected sensor type.

During operation between the displayed values for "TSET", "TACT", "ILIM" or "ITEC" can be
switched at any time by pressing (F17) or (F18).

3.2.1 Setting the TEC current limit

The Temperature Controller TED200C delivers a maximum TEC current of 2 A. Prior to switch
on the TEC output, an appropriate TEC current limit "ILIM" should be set using the
potentiometer "LIM I" in order to avoid damage of the TEC element.

A limitation of the maximum TEC current can be helpful to optimize the settling time in case of

a low thermal load (laser with low output power, set temperature close to environmental
temperature etc.)

Select the display parameter "ILIM" with the key (F17) or (F18).
Use a screwdriver to set the desired TEC current limit "ILIM" with the 12-turn potentiometer "LIM

I" (F12).

Note

The current limit can be displayed at any time by selecting the parameter "ILIM".

3.2.2 Adjusting Temperature Control Loop

Temperature controllers are used to manage the temperature of thermo-electrically heated/
cooled components in experimental setups, independent of external influences. To adapt a
controller to different thermal loads, and to optimize the controller’s response characteristics,
the controlling parameters of the system’s feedback loop must be optimized. All Thorlabs’
temperature controllers provide a PID control loop whose shares (P, I and D share) must be
matched with the thermal load of the device under test. For an optimum adaptation, these
parameters have to be adjusted separately and independent of each other. This section
describes how to optimize the PID parameters in order to get optimum performance from the

TED200C temperature controller.

· The P share (proportional, gain) can be adjusted with potentiometer "P" (F22).

· The I share (integral, off set control) can be adjusted with potentiometer "I" (F23).

· The D share (derivative, rate control) can be adjusted with potentiometer "D" (F24).

Preparation

1. Select "TACT" to display the actual temperature or thermistor resistance (keys F17 or F18).

2. Turn the three potentiometers "P" (F22), "I" (F23) and "D" (F24) completely counter­clockwise.

3. Switch off the I share to ease the setting of P and D shares: Press key (F25) for at least one
second to switch off the I share. The sensor LED (F19/F20/F21) is flashing to indicate the "I
share off" state.

4. Set the temperature "TSET" to a value around room temperature and switch on the TEC
current output (switch "ON" F9).

Adjust P share

Repeatedly increase and decrease the set temperature for about ± (1...2)°C around room
temperature using the tuning knob (F10) or by applying a suitable slow, square-wave signal to
the analog control input "TUNE IN" (R1) at the rear panel. Watch the settling behavior of the
actual temperature "TACT".

Note

The settling behavior can be observed at the "CTL OUT" output (R2).
Increase the P-share gradually by turning potentiometer (F22) clockwise.
Higher values will increase the settling speed. Too high values will increase the amplitude and

number of overshoots or will even make the system instable (continuous oscillation).
The P share is set correctly if the actual temperature remains stable near the set temperature

after only 2 … 3 overshoots.

Adjust D share

Change set temperature again repeatedly for ± (1...2)°C around room temperature while
observing the settling behavior of the actual temperature.

Increase the D share gradually by turning potentiometer (F23) clockwise.
Higher values will decrease the amplitude and number of overshoots. Too high values will

increase again the amplitude and number of overshoots or will even make the system instable.
The D share is set correctly if the actual temperature remains stable at a value near the set

temperature after a minimum of overshoots.

3 Operating Instruction

Adjust I Share

Turn on the I share, if it was if disabled, by pressing key (F25) for at least one second. The
sensor LED (F19/F20/F21) stops flashing if the I-share is enabled.

Change set temperature again repeatedly for ± (1...2)°C around room temperature while
observing the settling behavior of the actual temperature.

Increase the I share gradually by turning potentiometer (F24) clockwise.
Higher values will accelerate the settling to the set temperature. Too high values will increase

the amplitude and number of overshoots. The I share is set correctly when the actual
temperature reaches the set temperature in short time with at most one overshoot.

3.2.3 Over-Temperature Protection

The TED200C controllers come with an internal over-temperature protection. If the internal heat
sink is overheated, the output of the controller is disabled automatically. The LED "OTP" (F5)
lights up and a short beep is heard. The TEC current is switched off immediately. Pressing the
key "TEC ON" (F9) has no effect in this case.

After the internal heat sink's temperature decreased for about 10°C, the LED "OTP" (F6)
extinguishes and the laser current output can be switched on again.

3.2.4 Disabling the Beeper

If audible signals are unwanted, the beeper can be disabled in this way:

· Press and hold the key “UP” (F18).

· Press the key “Down” (F17). Now the beeper state is displayed:

· “Sd.ON” - Sound ON

· “Sd.OFF” - Sound OFF

To change the beeper state, hold the key “UP” pressed and toggle the beeper state by pressing
"DOWN" key.

4 Maintenance and Service

Protect the TED200C from adverse weather conditions. The TED200C is not water resistant.

Attention

To avoid damage to the instrument, do not expose it to spray, liquids or solvents!

The unit does not need a regular maintenance by the user. If necessary the unit and the display
can be cleaned with a cloth dampened with water. A mild 75% Isopropyl Alcohol solution can
be used for more efficient cleaning.

TED200C Controllers do not contain any modules and/or components that could be repaired by
the user himself. If a malfunction occurs, please contact Thorlabs for return instructions.

Do not remove covers!

27

To guarantee the specifications given in section Technical Data over a long period it is

21

recommended to have the unit factory calibrated every two years.

4.1 Line Voltage Setting

The TED200C operates at fixed line voltages of

100 V +15% / -10% ( 90 V … 115 V)
115 V +15% / -10% (104 V … 132 V)
230 V +15% / -10% (207 V … 264 V)

line frequency 50 … 60 Hz.
The line voltage setting can be changed from the rear without opening the unit.

1. Turn off the controller and disconnect the mains cable.

2. The fuse holder (R10) is located below the 3-pole power
connector of the mains jack (R8). Release the fuse holder
by pressing its plastic retainers with the aid of a small
screwdriver. The retainers are located on the right and left
side of the holder and must be pressed towards the center.

3. Unplug the white line voltage switch/indicator (R9,
containing the left fuse) from the fuse holder (R10), rotate it
until the appropriate voltage marking (100V, 115V, or 230V)
is on target for the cutout (R7) of the fuse holder, and plug
it back into the fuse holder. Press in the fuse holder until
locked on both sides. The appropriate line voltage marking

must be visible in the cutout (R7) of the fuse holder.

4.2 Replacing Mains Fuses

The two power input fuses are externally accessible. If they blew due to line distortions,
incorrect line voltage or other causes, they can be replaced from the rear without opening the
unit.

Attention

To avoid risk of fire only the appropriate fuses for the corresponding line voltage must be used

1. Turn off the TED200C and disconnect the mains cable.

2. The fuse holder (R10) is located below the 3-pole power

connector of the mains jack (R8). Release the fuse holder by
pressing its plastic retainers with the aid of a small screwdriver.
The retainers are located on the right and left side of the holder
and must be pressed towards the center.

3. Replace the defective fuses (R11) and press in the fuse
holder until locked on both sides. Take care to maintain the
correct rotation of the white line voltage indicator / switch (R9)
which contains the left fuse and is plugged into the fuse holder.
The appropriate line voltage marking must be visible in the
cutout (R7) of the fuse holder.

)Due to the nonlinear conversion from W to °C the stability in °C depends on the operating conditio ns and the

characteristics of the thermistor. E.g. for a typical thermistor at a set point of 10kW (25°C), a 0.5W stability
translates into about 1mK temperature stability. At a set point of 5kW (38°C), the stability is about 2mK.

5.5 Thorlabs 'End of Life' Policy (WEEE)

As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of the
European Community and the corresponding national laws, Thorlabs offers all end users in the
EC the possibility to return “end of life” units without incurring disposal charges.

This offer is valid for Thorlabs electrical and electronic equipment

· sold after August 13th 2005

· marked correspondingly with the crossed out “wheelie bin” logo (see figure below)

· sold to a company or institute within the EC

· currently owned by a company or institute within the EC

· still complete, not disassembled and not contaminated

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 products, such as

· pure OEM products, that means assemblies to be built into a unit by the user (e. g. OEM
laser driver cards)

· components

· mechanics and optics

· left over parts of units disassembled by the user (PCB’s, housings etc.).

Waste treatment on your own responsibility

If you do not return an “end of life” unit to Thorlabs, you must hand it to a company specialized
in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.

WEEE Number (Germany) : DE97581288

Ecological background

It is well known that waste treatment pollutes the environment by releasing toxic products
during decomposition. The aim of the European RoHS Directive is to reduce the content of
toxic substances in electronic products in the future.

The intent of the WEEE Directive is to enforce the recycling of WEEE. A controlled recycling of
end-of-life products will thereby avoid negative impacts on the environment.
