High Sec Labs Secure Galvanic Isolators are hardware security devices designed for use in Medical and Defence environments. They prevent vulnerable peripherals from acting as conduits between compromised and secure computers by providing complete galvanic isolation of DC and ground currents between two connected pieces of equipment. The product family includes multiple models supporting various video interfaces (e.g., HDMI), with at least one model supporting 4K30 resolution. Galvanic isolation is achieved through hardware-level separation, adding a physical security layer that cannot be bypassed via software. The use of a medical-grade PSU ensures compliance with applicable medical standards, enabling deployment across a broad range of medical applications. The isolators are BAA (Buy American Act) and TAA (Trade Agreements Act) compliant. Accessories available for the product family include: - RK-4U-HKS-10: A rackmount kit enabling up to 10 isolators to be mounted in a 19" 4U rack space. - PDUI (Power Distribution Unit for Isolators): Allows multiple isolators and other HSL 12V-powered devices to be connected to computers in a rack without requiring additional external power supply outlets.
