當沒有外接輔助電源時,NI-DCPower Soft Front Panel (SFP) 設定 PXI-4130 Channel 1 最大電流限制為 100mA。在沒有外接輔助電源時 PXI-4130 限制只能提供 2W 功率或是 300mA 電流。SFP最大電流限制為 100mA 因為這是在全電壓範圍 (+/- 20V) 之下而保持在 2W 功率限制內所能提供的最大電流。
要在 Soft Front Panel 設定更高的電壓限制要外接輔助電源。外接輔助電源應該要提供 11-15.5 V 並且高達 5 A。NI APS-4100 電源供應器可用於此。當外接輔助電源接上,必須確定外接電源的 LED 有亮起並重新啟動 SFP。此時最大電流限制應該是 2 A。
注意: 這應該是 NI-DCPower Soft Front Panel 的問題。當在程式 NI-DCPower 時沒有外接輔助電源的最大輸出限制是 300mA 或 2W。
