Overview
The L-com UH401-2KV is a single-port USB isolator designed to protect connected devices from electrical noise, surges, and ground loops. It provides 2 kV of isolation between the upstream host and downstream device. The unit is USB bus-powered and supplies up to 100 mA of current to attached downstream devices when connected to a full power (500 mA) USB host. It supports USB 2.0 Full Speed data rates up to 12 Mbps.
Feature Summary
- Provides 2 kV galvanic isolation to block electrical noise and ground loops
- USB bus-powered operation with downstream power delivery capability
- Compact form factor for space-constrained industrial environments
Applications
- Protecting sensitive PCs in electrically noisy industrial settings
- Connecting human interface devices such as mice or keyboards across isolated grounds
- Isolating low-speed USB peripherals in medical or laboratory equipment
Procurement Notes
Verify component authenticity through authorized L-com distributors. Confirm that the specific suffix '2KV' denotes the 2 kV isolation rating, distinct from other variants in the UH401 series. Ensure compatibility with USB 2.0 Full Speed requirements before procurement.
Selection Notes
Select this model specifically for applications requiring 2 kV isolation. Note that other models in the UH401 series, such as those without the '2KV' suffix, may offer different isolation ratings like 4 kV. Verify that the 100 mA downstream power limit meets the requirements of the connected peripheral.
Part Context
The UH401-2KV belongs to the L-com UH401 series of single-port USB isolators. This series includes variants with different isolation levels, such as 4 kV models. The product is categorized under special purpose isolators and is intended for protecting USB connections in harsh electrical environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Other models within the UH401 series, such as UH401SL-2KV, share similar specifications but may differ in connector type or physical form factor.
