Saelig debuts Intona 7055 USB 2.0/3.0 isolators with ESD protection

Saelig Company, Inc. introduced the Intona 7055 series USB 2.0/3.0 isolators, which provide galvanic isolation of any USB bus. Compatible with USB 2.0 High-Speed ​​480 Mbps and USB 3.0 SuperSpeed ​​5 Gbps, the 7055 isolation is designed to withstand up to 5 kVRMS, as well as advanced ESD protection up to 20 kV (IEC Airgap discharge). 7055 isolators work out of the box because no drivers are needed and communication is transparent to both host and device (“nohub”). These isolators offer wide compatibility with most operating systems, embedded systems and devices.

The Intona 7055 series USB 2.0/3.0 isolators are available in two versions: the Intona 7055-C model provides 1 kV DC isolation, transmitting USB SuperSpeed ​​(5 GBit/s) and Hi-Speed ​​(480 MBit/s), ensuring simultaneously full galvanic capacity isolation of both data and power lines; while the 7055-D is optically isolated and provides USB 2.0 + 3.0 communication with 5 kV RMS AC isolation. The 60-second insulation rating for the 7055D is 5000VRMS and 1000VDC for the 7055C.

The secondary side can be powered by an external 4.5-5.0V 2A auxiliary power supply for devices requiring high power. Up to 500 mA output current is available on the isolated side and up to 2000 mA output current when using the auxiliary power input. Power switching between internal and external power is automatic.

Ultra-quiet power rail isolation means less noise in highly sensitive applications which may include: industrial automation systems, medical devices, measurement devices, test equipment, environments requiring safety isolation, machine protection, broadcasts and studios, audiophile grade home systems, situations requiring clean and stable USB connections with separate grounds, etc.

Housed in an IP54 aluminum housing (4.7” x 2.8” x 1.2”) and weighing 11 ounces, the Intona 7055 USB 2.0/3.0 Isolators are available now from Intona technical distributor, Saelig Co. Inc.
