(a) The total combined current for the ITC133 is limited by the total thermal dissipation loss. Optimized cooling by fan or a larger heat sink allows 3 A LD and 3 A TEC at the same time, provided the power supply provides 6.1 A

All technical data are valid at 23 ± 5 °C and 45 ±15% relative humidity (non-condensing).
