高質量直流電源

2231A-30-3型電源基于線性化設計，每個輸出的噪聲低于5mVp-p。其電壓和 電流基本測量準確度分別是0.06%和0.2%。負載電壓和負載電流回讀結果提供同樣 級別的精度，因此您可以確信為待測器件(DUT)提供了高精度、低噪聲電壓和電流。

3個獨立的輸出

2231A-30-3型電源的每個輸出都是可編程的，可以彼此獨立地開啟和關 閉；它在1臺儀器內提供了3個電源。您可以通過同一臺儀器為印制電路板上的模擬 電路和數(shù)字電路上電，也可以為整個器件上電。

所有輸出都彼此隔離，且接地隔離

每個輸出都可以為不同接地基準的電路供電。每個輸出的低連接都不與其他輸 出相連。這意味著，一個電源可以測試3個不同接地基準上的3個獨立電路，或者為 變壓器電路或光隔離電路供電。此外，所有輸出都參考接地，因此2231A-30-3型 電源可以為浮動電路和接地電路供電。

High quality dc power supply

The model 2231a-30-3 power supply is based on a linearized design, with each output noise lower than the 5mvp-p. The basic measurement accuracy of voltage and current is 0.06% and 0.2%, respectively. The load voltage and load current read back results provide the same level of accuracy, so you can be sure that the device under test (DUT) provides high precision, low noise voltage and current.

Three completely independent outputs

Each output of the 2231a-30-3 power supply is fully programmable and can be turned on and off independently of each other. It provides three power sources in one instrument. You can use the same instrument to power analog and digital circuits on a printed circuit board, or to power the entire device.

All outputs are isolated from each other and are grounded

Each output can supply power to a circuit with a different ground reference. Each output low connection is not connected to the other outputs. This means that a single power supply can be used to test three separate circuits on three different ground bases, or to supply transformer circuits or optical isolation circuits. In addition, all outputs are reference grounded, so model 2231a-30-3 power supplies can be used for both floating and grounded circuits.
