L-COM ALECF504AB USB Surge Protector

The AL-ECF504-AB is a USB A female to USB B female surge suppressor designed to protect sensitive USB ports from electrical surges and spikes originating from connected devices. This commercial-quality device maintains USB 2.0 data transfer speeds by utilizing ultra-low capacitance diodes on the data lines and a clamp on the power lines for safety. Ideal applications include safeguarding computers from surges caused by Wi-Fi adapters, surveillance cameras with long USB extension cables, and USB-RS422/485 converters. The surge protector features a nickel-plated ABS plastic enclosure with a shielded design that mitigates EMI/RFI interference. It can be used inline or mounted in enclosures, and is compatible with any length of L-com USB A-B extension cables, which are sold separately. Suitable for various applications such as lighting, communications, networking, wireless systems, commercial setups, and security systems.
