Description

The SK41PHU-N is a 4-port single-head KVM switcher that consolidates keyboard, video, mouse, USB 3.0 and analog audio interfaces for four computers into a single desktop console. It supports DisplayPort and HDMI I/O and handles UHD 4K resolutions at up to 3840×2160. The product is designed to reduce peripheral clutter and simplify multi-system workflows – ideal for environments that require quick switching between machines.

Key features include hotkey and front-panel switching, four USB 3.0 peripheral ports, integrated audio and microphone jacks, and cross-copy clipboard/file transfer between connected systems. The switcher supports upstream USB Type B connections for each source and downstream USB Type A ports at the console for high-speed peripherals. Built-in copy and paste file transfer lets users move text and files between connected computers without a network link.

Performance supports UHD 3840×2160 at 30Hz across DP and HDMI interfaces and maintains standard HD audio via 3.5 mm analog jacks. The unit uses an external 12V DC, 1.5A power supply and complies with major regulatory certifications including CE, FCC class B, VCCI and TUV. Operating temperature range and humidity tolerances are suitable for typical control room and office environments.

Connectivity is comprehensive with one console DisplayPort or HDMI interface depending on configuration, four source DP/HDMI inputs, four USB Type B host ports and four downstream USB 3.0 Type A ports for shared devices. Analog mic and speaker jacks are provided at the console and at each computer port for two-way audio. The switcher is compatible with Windows, Linux and Mac operating systems for standard KVM control and USB peripheral sharing.

Practical applications include trading desks, broadcast and production control rooms, lab benches and multi-system engineering desks where rapid context switching is required. The SK41PHU-N reduces the need for dedicated peripheral sets per workstation and saves desk space where multiple PCs are in use. Its copy/paste and file transfer features streamline workflows that require moving data between isolated systems.

Installation is straightforward with plug-and-play USB peripheral detection, standard video cabling and a compact 1U-friendly enclosure footprint. Front-panel indicators and tactile push buttons provide clear status and selection control while keyboard hotkeys enable fast, hands-on switching. The external power supply simplifies rack or desktop deployment without internal power modifications.

In summary, the SK41PHU-N offers a practical 4K DP/HDMI KVM switching solution with USB 3.0 peripheral sharing and analog audio support. It combines simple installation, multi-OS compatibility and clipboard/file transfer capability to improve multi-computer operations. This unit provides cost and space savings for environments that require consolidated console access across four systems.
