ARC Technology
How does the ARC Keeper work?
Philips Bodine ARC Keeper® HID Backup Ballasts and e-ARC Keeper™ for 20-39 W Electronic HID Ballasts eliminate nuisance downtime in HID metal halide lighting systems and permit HID fixtures to serve as emergency lighting units. ARC Keeper and e-ARC Keeper work by preventing lamp arc loss during short-duration AC utility power disturbances that commonly threaten HID lighting systems.
ARC keeper in Action
HID lighting is highly sensitive to even very minor AC utility power disturbances. A disturbance of four milliseconds or greater can extinguish the lamp arc, creating the need for restrike. ARC Keeper and e-ARC Keeper units sense the disturbance and act before the lamp arc is jeopardized.
