GE DS2020FECNRX001A MKV数字接触端子板

产品描述

GE励磁板DS2020FECNRX001A具有7个跳线和2个接线端子，每个接线端子上有3个端子。跳线标识为 JP1 到 JP7。GE线路保护板DS2020FECNRX001A还包含多个插脚型连接器。该板安装在驱动器另一个组件的支架上。连接到电路板的信号线源自其所连接的组件。

该板装有四个电容器，由于电容器中存储的高压有触电风险，因此在处理电路板之前需要考虑它们。在正常处理过程中，电路板暴露在高压下，电容器存储电压。当指示这样做时，电容器将电流释放到电路板上的其他组件。大多数元件不存储电压，当电压从电路板上移除时，元件也无电压。然而，电容器会存储电压，因此在断电时触摸电路板的个人会受到威胁。

电容器仅将电压存储 30 秒，之后电压离开电容器，它们可以安全触摸。因此，请在从驱动器上断开电源后等待 30 秒，然后再触摸主板。

电路板上的 2 个保险丝可在电路板接收过多电流时保护电路板免受损坏。如果超过特定阈值，保险丝的额定熔断率。因此，如果更换保险丝，请仅安装具有相同额定值的保险丝。如果安装具有不同额定值的保险丝，保险丝可能会允许电流损坏电路板。或者，保险丝可能经常熔断。

Product description

The GE exciter DS2020FECNRX001A has 7 jumpers and 2 terminals, with 3 terminals on each terminal. The jumper is labeled JP1 through JP7. The GE line protection board DS2020FECNRX001A also contains a number of pin type connectors. The board is mounted on the bracket of another component of the drive. The signal wires connected to the board are derived from the components to which they are connected.

The board is equipped with four capacitors, which need to be considered before handling the board due to the high voltage stored in the capacitors, which is a risk of electric shock. During normal processing, the circuit board is exposed to high voltage, and the capacitor stores the voltage. When instructed to do so, the capacitor releases the current to other components on the circuit board. Most components do not store voltage, and when the voltage is removed from the board, the component has no voltage. However, capacitors store voltage, so individuals who touch the board during a power outage are at risk.

The capacitor stores the voltage for only 30 seconds, after which the voltage leaves the capacitor and they can be safely touched. Therefore, wait 30 seconds after disconnecting the power from the drive before touching the motherboard.

Two fuses on the board protect the board from damage if it receives too much current. The rated rate at which the fuse is blown if a specific threshold is exceeded. Therefore, if replacing fuses, only install fuses with the same rating. If a fuse with a different rating is installed, the fuse may allow current to damage the board. Or, fuses may blow frequently.
