Smart surge protection for Lexmark laser printers and MFPs Avoid damage from power line and telecom surges with the Lexmark Surge Protective Device, designed specifically for Lexmark’s full line of laser printers and MFPs. Two-way protection Using industrial-grade components, the Lexmark Surge Protective Device shuts off damaging current spikes before they can reach your Lexmark laser printer or MFP. Telecom lines can carry device-damaging surges too, so our surge protector stands guard over the fax line going into your Lexmark MFP. Upgraded circuit board Unlike typical consumer-grade surge protectors, the Lexmark Surge Protective Device's printed circuit board has two layers of glass fibre for better flame resistance, plus thicker two-ounce copper plating to spread and dissipate heat better. There’s also insulating tape and fibreglass component covers for an additional layer of heat protection during a surge event. Quality enclosure Lexmark’s specially-designed surge protector enclosure offers higher flame resistance than many consumer surge protectors. Plus, it has reinforced insulation construction with double retention features and is welded shut to resist tampering. Short-circuit protection Thermal cut-off fuses reduce the chance of short circuits if a sustained or exceptionally large surge causes internal component temperatures to rise to undesirable levels. The right connections The built-in 1.5 metre IEC appliance coupler cord attaches directly to a Lexmark device’s power connector, while the appliance inlet accepts your Lexmark device’s existing power cord. Protection status LED A blue LED indicates protection when lit and need for replacement when unlit.
