产品介绍
After disconnecting power to an enclosure, electricians can pre-verify voltage isolation while the enclosure door is safely closed. The risk of arc flash is reduced because electricians know if there is power inside the enclosure before re-verifying isolation with a meter.
The Voltage Vision (R-3W) is unmatched in its reliability due to its dual redundant circuitry and no separate power supply. Voltage Vision (R-3W) gets its power from the same voltage that it indicates! Ask this question: Can you live without it?

Panels with Multiple Power Source
VoltageVision® thru-door power warning alerts provide electrical safety information while the panel doors are safely closed. This “one-size-fits-all” solution detects 3-phase AC or DC voltage from 40-750VAC/30-1000VDC. The encapsulated construction and redundant circuit design means rugged reliability. Voltage is the common denominator in an electrical accident or an arc flash; no voltage means no accident, no arc flash. While performing electrical LOTO with a thru-door voltage detector installed, the electrician can pre-check the internal voltage state without opening the enclosure. Next, the electrician should replicate a zero voltage reading with his voltmeter as per NFPA 70e 120.1(5). This low-cost, redundant voltage-verification task reduces arc flash risk and increases electrical safety for workers.

Grace Engineered R-3W2 (Class 1 Division 2) 电压视觉
断开外壳的电源后,电工可以在外壳门安全关闭时预先验证电压隔离。电弧闪光的风险降低了,因为电工在用电表重新验证隔离之前就知道外壳内是否有电。
由于采用双冗余电路且没有单独的电源,Voltage Vision (R-3W) 的可靠性无与伦比。电压视觉 (R-3W) 从其指示的相同电压中获取功率!问这个问题:没有它你能活吗?
应用:
断路器断开 - 无可见刀片
高能面板(NFPA 70e 第三类和第四类)
经常访问的面板
机械乐透:指示零能量
多电源面板
当面板门安全关闭时,VoltageVision® 穿门电源警告警报可提供电气安全信息。这种“一刀切”的解决方案可检测 40-750VAC/30-1000VDC 的三相交流或直流电压。封装结构和冗余电路设计意味着坚固的可靠性。电压是电气事故或电弧闪光的共同点;没有电压意味着没有事故,没有电弧闪光。在安装了穿门电压检测器的情况下执行电气 LOTO 时,电工可以在不打开外壳的情况下预先检查内部电压状态。接下来,电工应根据 NFPA 70e 120.1(5) 用他的电压表复制零电压读数。这种低成本、冗余的电压验证任务可降低电弧闪光风险并提高工人的电气安全。
