Overview The PS-415-HGULTRA Medical-Grade Power Strip -- patent # 7,375,939 -- is the first power strip with full 60601-1 compliance and agency listing, making it ideal for standalone use in all patient care vicinities. This 120V, 50/60 Hz power strip features a NEMA 5-15P-HG hospital-grade plug and four NEMA 5-15R-HG hospital-grade outlets that include integrated locking safety covers. A patented protection circuit guards against shock hazards by preventing power from reaching the units outlets in the presence of a fault. The protection circuit automatically resets itself and restores power once the fault threat is gone. Mounting tabs and flanges let you install the PS-415-HGULTRA on a wide variety of surfaces. The all-metal housing ensures safety and is guaranteed to last a long time in demanding environments. With a switchless design that prevents accidental shutoff and a 15-foot power cord that can reach a distant power source, the PS-415-HGULTRA is a recommended replacement for all non-compliant power strips.
