USB 3.0 SuperSpeed 10-36V Isolator (ADQ-USB-ISO-W)

The Alldaq ADQ-USB 3.0-ISO-W USB 3.0 Isolator supports the full USB 3.0 SuperSpeed data rate of 5Gbit/s and can accept 10 to 36 VDC from an external power source via a 2-pin lockable Phoenix-type connector to power devices with up to 900 mA. The external power input is protected against reverse polarity and short-circuits. This allows USB 3.0 SuperSpeed devices to be electrically isolated from a host PC or other peripherals at full performance. The re-clocking design guarantees a stable USB connection at all speeds. The ADQ-USB isolators can be used for the electrical isolation of USB measurement instruments to avoid ground loops to solve problems in industrial and automotive applications as well as in professional sound studios and event and show equipment.  The ADQ-USB 3.0-ISO isolators automatically detect SuperSpeed (5Gbit/s), High-Speed (480Mbit/s), Full-Speed (12Mbit/s) or Low-Speed (1.5 Mbit/s) connections

The isolation voltage between PC and USB device is 1kV (<60s). The ESD protection of the data lines is ensured by transient-voltage-suppression diodes up to ±12kV (contact discharge) and  ±15kV (air-gap discharge) according to IEC 61000-4-2. The Alldaq USB 3.0 isolators are compatible with Windows, MAC OS and Linux systems, and downward-compatible with USB 2.0/1.1/1.0 equipment.

Housed in a robust aluminum housing with rubber bumpers and designed for an operating temperature from -20 to +70degC, the Alldaq USB 3.0-ISO isolators are suitable even for applications in harsh environments.  An optional DIN rail mounting kit is also available for permanent installations.

The ADQ-USB 3.0-ISO can protect computers and USB devices effectively against interference voltages, while also eliminating ground loops. Typical applications include: electrical isolation between measurement instruments and PCs, rejection of ripple pickup in studio equipment, removing differing ground potentials in industrial control equipment, and protection against voltage peaks in automotive set-ups.

The Alldaq ADQ-USB 3.0-ISO-W USB 3.0 Isolator is compact in size (3.6” x 2.5” x 1.3” - L x W x H incl. rubber bumpers) and weight (4.5oz).

Application examples

• Electrical isolation between measurement instruments and PC
• Efficient suppression of ground loops – Ideal for music studios and event technology
• Spike protection in the automotive area, e. g. for testing control units
• Decoupling of different ground levels in industrial control technology
• Can also be used as “power injector“ for USB devices normally powered by the USB port but which can´t provide enough current for a reliable operation of the USB device.
