Saelig Company is offering Alldaq’s ADQ-USB 3.0-ISO series USB 3.0 isolators that support the full USB 3.0 SuperSpeed data rate of 5 Gb/s. This allows USB 3.0 SuperSpeed devices to be electrically isolated from a host PC or other peripherals at full performance. A re-clocking design guarantees a stable USB connection at all speeds. The 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 (5 Gb/s), High-Speed (480Mbit/s), Full-Speed (12Mbit/s) or Low-Speed (1.5 Mbit/s) connections. The model ADQ-USB 3.0-ISO-PS includes a +5 V power adapter with a lockable 5.5mm barrel connector (bayonet lock) for a safety. For industrial and automotive applications, the ADQ-USB 3.0-ISO-W version 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.
The isolation voltage between PC and USB device is 1kV (continuous) for the model ADQ-USB 3.0-ISO-PS and 1.0kV (< 60s) 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 ±12kV (contact discharge) and ±15kV (air-gap discharge) according to IEC 61000-4-2. Without an external power supply the USB isolator can source up to 200mA at the device port. For USB devices requiring more current, the external power supply version ADQ-USB 3.0-ISO-W can provide 900 mA according to the USB 3.0 specification. 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.
