The TECA1-xV-xV-DAH TEC controller can come with an
internal compensation network for stabilizing the
temperature control loop. The compensation network with
the default values shown in Figure 4 matches most of the
commonly used butter-fly packaged TEC thermal loads. The
part number TECA1LD-xV-xV-DAH, with the "LD" suffix,
stands for the controller with an internal compensation
network; while the part number TECA1-xV-xV-DAH,
without the "LD" suffix, stands for the controller without the
internal compensation network and external compensation
network will be required for the controller to operate. The
compensation network is made of 5 components: 3 resistors
and 2 capacitors. This network can be implemented either
internally by embedding them into the controller circuitries
inside the controller enclosure or externally by soldering the
5 components on the PCB (Printed Circuit Board) on which
the TEC controller is mounted.
