Altronix VERTILINE48MD 16-Output 48VDC Rack-Mount Power Distribution Unit

Overview

The Altronix VERTILINE48MD is a 16-output, 48VDC centralized power distribution unit built for rack-mounted security and IP surveillance infrastructure. Drawing 5A at 115VAC/50-60Hz and delivering 56VDC at up to 6.5A total output, the VERTILINE48MD is engineered for installations where you need individually protected power circuits across a dense channel count — all in a single 19-inch rack unit. Each output is PTC-protected at 2.5A, which means a fault on one run won't cascade and take down adjacent devices. If you're wiring a mid-to-large IP camera deployment or structured access control rack, this unit centralizes power distribution in a way that makes troubleshooting and expansion far more manageable than daisy-chained supplies.

For integrators building out Altronix power solutions into rack-enclosure designs, the VERTILINE48MD fits the standard 19.125-inch rack width and occupies a 3.26-inch vertical profile — plan your U-space accordingly in dense builds. Its 13.75 lb. installed weight means it needs proper rail support; don't float it on shallow shelves.

Key Features

• 56VDC Output at 6.5A Total: Delivers 56VDC across all 16 outputs — enough headroom above the nominal 48V to compensate for voltage drop over longer wire runs to powered devices. On longer home-runs in warehouse or campus deployments, that extra margin matters more than it sounds.
• 16 Individually PTC-Protected Outputs at 2.5A Each: Polymeric PTC (positive temperature coefficient) protection on every output means a shorted or overloaded run self-limits and resets without manual fuse replacement. In a 16-camera rack you're not pulling boards to swap blown fuses at 2 AM — the circuit recovers automatically once the fault clears.
• 6.5A Total Output Budget: Across all 16 outputs, the unit supports 6.5A combined draw. This is the constraint to plan around: 16 × 2.5A individual PTC ratings don't add up to 40A — the system total is capped at 6.5A. Size your per-camera or per-device draw accordingly and don't load all outputs to their individual maximums simultaneously.
• 5A Input at 115VAC/50-60Hz: Standard North American single-phase input with 50/60Hz compatibility. One standard 15A circuit breaker handles this unit with margin; no dedicated 20A circuit required for a single VERTILINE48MD.
