Voltage Monitor alerts users to dangerous panel conditions.
Press Release Summary:
Mounted inside control panel via DIN rail, VoltageVision(TM) Power Warning Alert locates every power source inside panel to maintain electrically safe work conditions. It enables those performing maintenance on open control panels to see voltage state of every power source. Hardwired into any power source, unit flashes whenever hazardous voltage is present in any single/3-phase or dc power system. System detects ac and dc voltage and operates from 40-750 Vac/30-1,000 Vdc.

"Is there voltage and does the electrician know it?
[Davenport, IA: August 22, 2005] - Locating every power source inside a panel is critical for creating and maintaining an "electrically safe work condition". The R-3W-DIN DIN rail mount bracket provides a means to install the VoltageVision(TM) Power Warning Alert (R-3W) inside a control panel. Electricians performing maintenance on open control panels can now 'See' the voltage state of every power source within the panel. This helps ensure that work conditions remain "electrically safe" in the event that normal safety procedures are violated. The R-3W is hardwired into any power source and will flash whenever hazardous voltage is present in any single/3-phase or DC power system.
Voltage is the single determining factor if an electrical accident or an arc flash is possible--No voltage means: No accident, No arc flash. The theme of the NFPA 70e is "Voltage or No Voltage" and addresses two issues: a.) Establishing an electrically safe work condition, and b.) Achieving safety while working on energized systems. VoltageVision reduces the risk of electrocution, because it is hardwired and provides the electrician a second reliable unattended voltage check during routine maintenance. Currently, electricians check voltages only periodically during maintenance. VoltageVision installed in 600V electrical panels, switchgear, or Motor Control Centers enhances compliance with the NFPA 70e and OSHA lockout tagout/stored energy procedures. Electrocutions rank 4th in occupational fatalities in the US.
The VoltageVision R-3W is "one-size-fits-all" because it detects both AC & DC voltage and operates from 40-750VAC/30-1000VDC. The encapsulated construction and redundant circuit design provide superior reliability. The R-3W is C-UL-US Nema 4X listed, and fits into a standard 30mm pushbutton hole.
