![]() ![]() 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. 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. Without an external power supply, the USB isolator can source up to 200 mA at the device port. The ESD protection of the data lines is ensured by transient-voltage-suppression diodes up to ☑2 kV (contact discharge) and ☑5 kV (air-gap discharge) according to IEC 6. The isolation voltage between PC and USB devices is 1 kV (continuous) for the model ADQ-USB 3.0-ISO-PS and 1.0 kV (less than 60 seconds) for the model ADQ-USB 3.0-ISO-W. The external power input is protected against turn polarity and short-circuits. For industrial and automotive applications, the ADQ-USB 3.0-ISO-W version can accept 10 to 36 V DC from an external power source via a two-pin lockable Phoenix-type connector to power devices with up to 900 mA. The model ADQ-USB 3.0-ISO-PS includes a +5 V power adapter with a lockable 5.5 mm barrel connector (bayonet lock) for safety. The ADQ-USB 3.0-ISO isolators automatically detect super speed (5 Gbit/s), high-speed (480 Mbit/s), full-speed (12 Mbit/s) or low-speed (1.5 Mbit/s) connections. 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 re-clocking design guarantees a stable USB connection at all speeds. This allows USB 3.0 super speed devices to be electrically isolated from a host PC or other peripherals at full performance. Saelig has introduced the Alldaq ADQ-USB 3.0-ISO series of USB 3.0 isolators, which support the full USB 3.0 super speed data rate of 5 Gbit/s. ![]()
