Industrial Grade Surge Protective Devices     Leviton's Surge Protective Devices (SPD's) are designed to reduce the random energy surges of voltage transients and electrical noise on the power supply line. Volatile transients and noise are present in utility power lines, data networks, telephone lines, closed circuit and cable tv feeds, and any other power or control lines connected to electronic equipment.   Leviton's Surge Protective Devices can be used individually or as part of a coordinated application strategy, called Network Protection, to protect sensitive electronic equipment in industrial, commercial and residential locations from the stress and degradation inflicted by voltage transients. Leviton Surge Protective Devices are listed to UL 1449 Second Edition Standards. Leviton's outstanding Surge Protective Devices divert damaging voltage transients, or surges, away from electronic equipment. Transients are diverted away from sensitive microcircuitry, providing protection against catastrophic failure, costly downtime and data disruptions.   Features and Benefits Provides seven-mode protection User-replaceable modules Real-time diagnostics monitor power and suppression status for each mode Diagnostic display panel of 75000/75000 units indicates "Fault", "Alert" and "Protection" status Provides surge magnitude, time and date of each surge event Surge event history downloadable via RS-232 connection   Surge Protective Device Literature Power Quality Products Leviton's Surge Protection Devices protect electronic equipment against damaging and disruptive.     Surge Protection Catalog View the Power Quality Solutions product catalog.
