If you choose to assemble custom interconnect cables, 18AWG wire is recommended to minimize
voltage drop at high current. Note that the DB-25 connector pins are rated for I
nominal
= 2.5A, therefore
all four TEC+ pins (9, 10, 21, 22) must be used if 8 A is to be delivered to a load as well as all 4 TEC-
pins (12, 13, 24, 25) for the return.
Cable ID pin configurations will determine the maximum output current for the TEC and is only
applicable to products with the 25-pin D-sub connector.
