Black Box PS290 12-VDC Power Supply for USB Hubs | Adapter, 4-kV

Maintain reliable power delivery for USB hub deployments with the Black Box PS290. This external supply provides 12-VDC output from a wide 100-240-VAC input range, making it suitable for mixed office environments, lab benches, and distributed installations where power standards vary by region. The locking barrel plug is a practical detail that matters in real deployments. It helps keep the connection secure when hubs are mounted under desks, moved between workstations, or used in areas where cables are frequently handled. The included U.S., U.K., and EU adapter inserts further reduce friction for teams supporting international offices or traveling kits. A 4-kV isolation rating adds protection for sensitive equipment by helping guard against surges. That makes this supply a better fit than generic adapters when uptime, device protection, and deployment consistency matter. For IT teams standardizing USB hub accessories, it offers the kind of dependable power component that keeps peripherals available without introducing avoidable support calls.
