To ensure safe operation of the WTC32ND
Thermoelectric Controller, it is imperative
that you determine that the unit will be
operating within the internal heat dissipation
Safe Operating Area (SOA).
Visit the Wavelength Electronics website for the most
accurate, up-to-date, and easy to use SOA calculator:

Figure 1 shows the pin layout and descriptions for the
WTC32ND.
IF YOU ARE UPGRADING FROM THE WHY SERIES:
The position of Pin 1 on the WHY is reversed (or mirrored)
relative to the position of Pin 1 on the WTC32ND.
