高质量直流电源

2231A-30-3型电源基于线性化设计，每个输出的噪声低于5mVp-p。其电压和 电流基本测量准确度分别是0.06%和0.2%。负载电压和负载电流回读结果提供同样 级别的精度，因此您可以确信为待测器件(DUT)提供了高精度、低噪声电压和电流。

3个独立的输出

2231A-30-3型电源的每个输出都是可编程的，可以彼此独立地开启和关 闭；它在1台仪器内提供了3个电源。您可以通过同一台仪器为印制电路板上的模拟 电路和数字电路上电，也可以为整个器件上电。

所有输出都彼此隔离，且接地隔离

每个输出都可以为不同接地基准的电路供电。每个输出的低连接都不与其他输 出相连。这意味着，一个电源可以测试3个不同接地基准上的3个独立电路，或者为 变压器电路或光隔离电路供电。此外，所有输出都参考接地，因此2231A-30-3型 电源可以为浮动电路和接地电路供电。

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.
