ALLDAQ: USB 3.0 SuperSpeed isolator for industry and audio

ALLDAQ presents USB 3.0 isolators supporting the full USB 3.0 SuperSpeed data rate of 5 Gigabit/s. The new re-clocking technology guarantees a stable USB connection for all speeds. With it also USB 3.0 SuperSpeed devices can be electrically isolated from the host PC at full performance. The isolators can be universally used for electrical isolation of USB measurement instruments, to avoid ground loops in industry and automotive area as well as in professional studio and event technology e. g. for streaming of numerous audio tracks via USB audio interfaces.

The USB isolators of the ADQ-USB 3.0-ISO series detects automatically, whether it is a SuperSpeed (5 Gbit/s), High-Speed (480 Mbit/s), Full-Speed (12 Mbit/s) or Low-Speed (1,5 Mbit/s) connection. The isolation voltage between PC and USB device is 1 kV (continuously) for the model ADQ-USB 3.0-ISO and 1.6 kV (< 60 s) for the model ADQ-USB 3.0-ISO-W. The ESD protection of the data lines is ensured by transient-voltage-suppression diodes up to ±15 kV according to IEC 61000-4-2. Without an external power supply the USB isolator can source 200 mA maximum at the device port. However, for most USB devices an external power supply is required providing 900 mA according to the USB 3.0 specification. The model ADQ-USB 3.0-ISO is sourced via an +5 V power adapter with a lockable 5.5 mm barrel connector (bayonet lock) for a safe power supply. Especially for industrial and automotive applications a version with wide range input from 10 to 36 VDC is provided. Here the power supply is fed via a 2-pin Phoenix type connector. The external power input is protected against reverse polarity and short-circuit proof. The ALLDAQ USB 3.0 isolators are supported under Windows, MAC OS and Linux.

Due to the robust aluminium housing and an operating temperature from -20 to +70°C, the USB 3.0 isolator is also suitable for applications in harsh environments. With the ADQ-USB 3.0-ISO you can protect your computer and USB devices effectively against interference voltages and avoid ground loops. Typical applications are: electrical isolation between measurement instrument and PC, rejection of ripple pickup in studio technology, de-coupling of different ground potential in industrial control technology and protection against voltage peaks in automotive area.

With the ALLDAQ USB 3.0 isolators a double-shielded USB 3.0 cable (USB 3.0-A male connector to USB 3.0-B male connector) and a short description are included. The devices are manufactured in Germany according to highest quality standards.
