Description
L-com’s AL-ECF504-ABxx series USB surge protectors are a commercial quality device designed to protect a
computer’s sensitive USB ports from power surges and spikes from attached devices. To ensure USB 2.0 speeds,
the device uses ultra-low capacitance diodes to protect the data lines. In addition, a protection device clamps the
power lines to safe levels. This USB surge protector is ideal for protecting a PC from WiFi client adapters and
surveillance cameras used with long USB extender cables. Other uses include protection from surges when using
USB-RS422/485 converters with long cables.
The AL-ECF504-ABxx can be mounted in an enclosure, panel, wall plate, or used in-line as a standalone product.
It features a fully shielded pigtail cable available in lengths from 12” to 72”.
