Metered Cabinet PDU

The Server Technology PDU 4-Output Sentry Metered Cabinet 441 distributes mains power to four connected devices while reporting real-time load data. It is built for rack-mounted infrastructure where administrators need per-outlet visibility without adding external monitoring gear. The unit suits colocation cages, edge sites and lab rows that run on standard cabinet power feeds. Buyers who need more than four outlets or require switched control per outlet should look elsewhere.

Thermals noise and power draw

Passive internal components generate minimal heat and no audible fan noise during normal operation. The metering circuitry draws only a small fraction of the total throughput, leaving virtually all capacity for attached equipment. No active cooling is required, so the unit adds no measurable acoustic load to the rack environment.

Questions about this item

How do I mount the Sentry Metered Cabinet 441 in my rack, and what step is often missed?

Secure the PDU to the cabinet rails using the supplied brackets; the step often missed is verifying the outlet orientation matches your equipment layout before tightening all screws.

What maintenance will the Sentry Metered Cabinet 441 need over time?

Periodically inspect the power cords and outlet contacts for dust or heat discolouration; the built-in metering lets you track load trends so you can replace cables before they degrade.
