New solid-on thru-door power warning alert
Grace Engineered Products’ VoltageVision Power Warning Alerts provide electricians with electrical safe information while the panel doors are closed.
Davenport, Iowa, April 15, 2010—Creating an electrically safe work condition is critical for electricians performing maintenance on de-energized systems. The VoltageVision Power Warning Alerts from Grace Engineered Products provide electricians with electrical safe information while the panel doors are closed and are now available in a new model solid-on type.
The new solid-on model type, part number R-3W-SR, is nearly identical in purpose and function to its flashing counterpart—except the LEDs simply illuminate to show the presence of voltage rather than blink (Note: LED appearance for differing voltages as follows: 32-159V(FLASH) 160-329V(SHIMMER) 330V+(SOLID)).
The R-3W-SR is still a "one-size-fits-all" solution because it detects three-phase ac or dc voltage and operates from 40-750 Vac/30-1000 Vdc. The encapsulated construction and redundant circuit design provide superior reliability. The R-3W-SR is C-UL-US NEMA 4X listed, and fits into a standard 30mm push-button hole.
