Thermoelectric Cooler (TEC) Controls:
The SLED TEC is used to control the bench temperature of the SLED. The TEC is turned
ON/OFF by toggling the enable button. Note that if a user turns the SLED TEC off, the
driver will automatically turn off the SLED to avoid overheating and damage.
Users can set their desired TEC temperature by clicking the
“
Save
”
button beside the
“Set
Point
”
box; see Figure 9. Factory default recommended value is 21
˚C
. The real-time
TEC temperatures are shown in the
“
Temp Read
”
box and TEC Current is shown in the
“
Current Read
”
box. TEC Capacity represents how hard the TEC is working to maintain
the temperature of the SLED. At 100% capacity, the TEC is working at its maximum
capacity to maintain this temperature.

Fan Controls
Factory default settings will automatically control the air flow. When the unit is
powered on, fan speed will default to its maximum value. Realtime fan speed is read
from the unit and displayed in the fan speed “Reading” box.
To change the fan speed, the user may type a desired fan speed value (0.0 to 7.0 CFM)
into the fan speed “Set Point” field, then click the “Set”
Button.
Note: The user-defined fan speed Set Point will not be saved when the unit is powered
off. It is recommended to run the unit only at factory default fan speed.
