产品介绍
The new R-1A0033W-NPLPH assembly, known as the Interactive Functioning Voltage Label, consists of a Voltage Vision R-3W voltage indicator, three ChekVolt R-1A voltage portals and a polycarbonate UV-rated nameplate. The panel mount assembly provides two independent means of checking for the absence or presence of voltage with the control panel still closed. Field retrofits are simple because the nameplate includes pilot hole drilling locators. The ChekVolt R-1A mounts in a ½" hole and the Voltage Vision R-3W mounts in a standard 30mm pushbutton hole. For disconnect enclosures, R-1A0033W-NPLPF is designed to mount on a flange rather than a door.
NFPA 70E requires voltage sources to be labeled on the outside of all electrical enclosures. In the past, these labels merely conveyed stagnant information that still required personnel to open panel doors to identify, verify and locate all voltage sources thereby putting workers at risk. Now, the concept of an interactive, functioning voltage label provides personnel with the ability to both visualize and verify the state of each electrical energy source feeding the enclosure - with the panel doors closed.

ChekVolt extends a voltage point to the outside of an electrical enclosure so that a Non-Contact Voltage Detector (NCVD) can be used to check for AC voltage without access to the inside of the enclosure.
-
VoltageVision® is a UL-listed device that functions like a permanently mounted voltmeter that monitors both AC and DC voltage between each phase and phase-to-ground. When a phase is lost the LED's corresponding to that phase will go out giving a visual indication of a problem outside of the panel.
Grace Engineered R-1A0033W-NLPPH ChekVolt 和电压视觉组合
新的 R-1A0033W-NLPPH 组件称为交互式功能电压标签，由一个电压视觉 R-3W 电压指示器、三个 ChekVolt R-1A 电压端口和一个聚碳酸酯紫外线额定铭牌组成。面板安装组件提供了两种独立的方式来检查是否存在电压，而控制面板仍处于关闭状态。现场改造很简单，因为铭牌包括导向孔钻孔定位器。 ChekVolt R-1A 安装在 ½" 孔中，Voltage Vision R-3W 安装在标准 30mm 按钮孔中。对于断开式外壳，R-1A0033W-NPLPF 设计为安装在法兰上而不是门上。
NFPA 70E 要求在所有电气外壳的外部标记电压源。过去，这些标签仅传达停滞的信息，仍然需要人员打开面板门来识别、验证和定位所有电压源，从而使工人处于危险之中。现在，交互式、功能性电压标签的概念使人员能够在面板门关闭的情况下可视化和验证为外壳供电的每个电源的状态。
ChekVolt 将电压点延伸到电气外壳的外部，以便非接触式电压检测器 (NCVD) 可用于检查交流电压，而无需进入外壳内部。
VoltageVision® 是 UL 列出的设备，其功能类似于永久安装的电压表，可监控每相和相对地之间的交流和直流电压。当一个相位丢失时，对应于该相位的 LED 将熄灭，给出面板外部问题的视觉指示。
