Surge Suppressors/Protectors

Heavy Duty USB Isolation

The UHR401 and UHR402 are one and two port 4 kV USB isolators with heavy industrial EMC specifications and our signature high retention USB connectors. The 4 kV Isolation protects expensive equipment from dangerous ground loops and helps ensure data integrity. The Heavy Industrial EMC specifications allow these isolators to operate in unfriendly electrical environments - such as near variable frequency drives, motor control centers, welding, and other large electrical loads. The high retention USB connectors hold standard USB cables tight and are perfect for high vibration applications, requiring a minimum of 3.2 lbs.-force to disconnect them. The products have also been tested for shock, drop, and vibration. Due to the nature of isolation and USB, bandwidth is limited to 12 Mbps..

The UHR401 and UHR402 are One and Two Port Ruggedized Isolators. They are designed and tested to meet heavy industrial EMC standards. High retention USB connectors hold standard USB cables tight and are perfect for high vibration applications - requiring up to 3.2 lbs-force to disconnect them. They have 4 kV Isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity. They are also suitable for integration into medical applications requiring 60601-1 certification.

Compact, In-line USB Port Isolation

The UH401 family of USB Port Isolators is available in 4 kV or 2 kV versions. They are used to protect your expensive equipment from dangerous ground loops and to help ensure data integrity in electrically noisy environments. The high retention USB connectors hold standard USB cables tight, requiring a minimum of 3.2 lbs.-force to disconnect them. These in-line devices come in several variations, including versions with 4 kV and 2 kV protection, Full Speed (12 Mbps) USB, and Low Speed (1.5 Mbps) USB. As with our other isolators, protection for High Speed (480 Mbps) is not supported due to industry wide limitations.

Model HESP4DR is designed to help protect against lightning strikes, power surges, and other types of voltage disturbances to components on a DIN rail. Five RS-422/485 signals on terminal blocks are supported with a clamping voltage of approximately 6.8 volts. The HESP4DR offers three stages of protection starting with a gas discharge tube followed by a series resistor and finally a Transient Voltage Suppressor (TVS).
