Table 2. Characteristics (Tambient=25°C)

  • Object temperature refers to the actual cold side temperature of the TEC, on which the target is mounted.

** Set-point temperature is the temperature desired to have on the target. *** Can be customized to any range according to the requirement. **** This TEC controller can only drive the TECs having > 1Ω impedance, which equals VMAX/IMAX. The block diagram of the controller is shown in Figure 3. Figure 3. TEC Controller Block Diagram

package controller is shown in Figure 10. Figure 10. Dimensions of the DIP Package Controller of TECA2-xV-xV-DAH by a solder iron of < 310°C (590°F), they cannot go through a reflow oven process.

  1. Connect the controller solid well with the power supply before turning on the power.
  2. Make sure that the power supply has sufficient out put current. It is suggested that the power supply can

supply 1.2 to 1.5 times the maximum current the controller requires.

  1. When using a bench top power supply, set the current limit to >1.5 times higher than the maximum current
