AC/DC电流传感器可以测量较大的直流和交流电流。
电流输出模式可以将AC/DC电流传感器连接至WT系列功率分析仪以及PX8000高精度功率分析仪的直接电流输入端子,供测量之用。使用单个功率计时,您可以通过直接输入测量非常小的电流,或使用电流传感器测量最大至2000A的大电流(使用751552钳式探头测量最大至1400A的大电流)。AC/DC电流传感器可用于许多应用领域的大电流和大功率测量,如混合动力与纯电动汽车、电池、变频电机、能源、铁路和工业电机。

Connection examples* making use of built-in DC power supply (/PD2 option)
*1: Use an insulated conductor or cable for wiring on the primary side.
*2: When connected to CT2000A current sensors, use DC power supply option (/PD2) for WT1800E or PX8000.
Combination among CT current sensors, dedicated cables and Shunt Resistor Boxes
Current limitations of the /PD2 option when using CT2000A
When connecting the current sensor, CT2000A, to the DC power supply option (/PD2) terminals on a WT1800E or PX8000 Power Analyzer, make sure that the output current does not exceed the range shown below.
WT1800E | PX8000 |
(Total current consumption for channel 1 through 6) ≤ 6 A |
(Total current consumption for channel 1 through 4) ≤ 4 A |
Connection example*
Using external DC power supply
* Use conductors or cables with reinforced insulation for primary input.
* Make sure that the total load resistance including measuring instrument’s internal resistance and external load resistance (Rb) is within the specification to prevent oscillation. And confirm the rated power specification of the load resistance.
