APC NetShelter Switched 3-Phase 17.3kW 42 Outlets Rack Power Distribution Unit

The APC APDU10452SW is a rack power distribution unit that provides switched outlet control and supports a three phase input. It supplies up to 17.3 kW, making it a solid choice for dense server, storage, or networking installations where power headroom and precise management are critical.

This model fits easily into a standard 19-inch rack because the enclosure is only 2.2 inches wide. Inside that slim profile are forty two outlets built around a 4-in-1 combination design, so each outlet can accept C13, C19, C15, or C21 plugs. The flexible layout simplifies deployment when equipment mixes change or when high-density blade chassis need additional C19 or C21 receptacles.

For day-to-day oversight, the unit reports real-time current, voltage, and energy use with 1 percent accuracy. You can view data locally or through remote tools that speak HTTP, HTTPS, or SNMP, and the integrated gigabit Ethernet port keeps traffic moving even on busy management networks. Outlet-level switching lets administrators turn individual devices on or off, schedule power cycling, or lock unused receptacles to prevent accidental overloads.

Reliability features include an alternating phase design that shortens power cord runs and improves load balancing, along with power-sharing circuitry that keeps the network interface alive if the primary input source is lost. The hot-swappable Network Management Card can be replaced without interrupting power to connected gear, keeping maintenance windows short and predictable.

Rated to operate at up to 60 °C, the APDU10452SW handles the higher ambient temperatures of modern, air-flow-constrained racks. Data center operators, colocation providers, and branch IT rooms that need scalable power distribution with granular control will find it a practical, future-proof solution.
