    DC sourcing power and sinking power are limited to the values in the following table, regardless of output voltage. [3]

    Table 2. DC Sourcing & Sinking Power
    Model Variant Chassis Type DC Sourcing Power DC Sinking Power
    PXIe-4135 (40W) ≥58 W Slot Cooling Capacity 40 W 40 W
    <58 W Slot Cooling Capacity 20 W 12 W
    PXIe-4135 (20W) ≥58 W Slot Cooling Capacity 20 W 12 W
    <58 W Slot Cooling Capacity 20 W 12 W
    spd-note-caution
    Caution  

    Limit DC power sinking to 12 W where applicable as indicated in the above table. For <58 W cooling slots,

    • Additional derating applies to sinking power when operating at an ambient temperature of >45 °C.
    • If the PXI Express chassis has multiple fan speed settings, set the fans to the highest setting.
    • 1 Voltage levels and limits >|40 VDC| require the safety interlock input to be closed.
    • 2 Current is limited to 1 A DC. Higher levels are pulsing only.
    • 3 Power limit defined by voltage measured between HI and LO terminals.
