*15: If the current is greater than Imax, the heat absorption begins to decrease due to the Joule heat. It should be noted that
this value is not a damage threshold. To protect the thermoelectric cooler (Peltier element) and maintain stable operation,
the supply current should be less than 60 % of this maximum current.
*16: Temperature at hot side of thermoelectric cooler.
*17: ∆T=Th - Tc
*18: This is a theoretical heat absorption level that offsets the temperature difference in the TE-cooled element when the
maximum current is supplied to the unit.
*19: Temperature at cool side of thermoelectric cooler.
