Server Technology C1L24VS-4PFA11F2/C 0U Rack PDU Expansion Unit

Overview

The Server Technology C1L24VS-4PFA11F2/C is a Smart PRO1 expansion unit built as a 0U rack power distribution module — 24 total outlets packed into a zero-rack-unit vertical form factor that mounts in the rear channel of a server cabinet without consuming any usable rack space. For data center and network closet builds where every U counts, that's the whole appeal: outlet capacity added without giving up a single slot for compute or switching gear.

Key Features

• 18x IEC C13 outlets: covers standard servers, switches, and most IT gear with C14 power cords — the majority of rack-mount equipment in a typical cabinet.
• 6x IEC C19 outlets: handles higher-draw equipment such as blade chassis, high-density servers, and larger UPS-fed loads that require C20 cords and can't run on standard C13 connections.
• 24 total outlets on one unit: consolidates power distribution for a fully populated rack onto a single expansion module rather than spreading gear across multiple lower-density strips.
• 0U form factor: mounts vertically along the rack frame, so outlet expansion doesn't cost you horizontal rack space you'd otherwise sell to revenue-generating equipment.
• Expansion unit design: built to extend outlet capacity on a Smart PRO1 deployment — relevant when a primary PDU's outlet count runs short as a cabinet fills up with additional servers or network gear.

Integration & Compatibility

As an expansion unit (Smart PRO1 series), the C1L24VS-4PFA11F2/C is designed to extend an existing Smart PRO1 power distribution deployment rather than operate as a standalone primary PDU. When you're planning a rack build, pair outlet capacity planning with your power distribution and UPS equipment selection up front — retrofitting outlet count after a cabinet is already populated is far more disruptive than sizing it correctly during initial buildout. The mixed C13/C19 outlet configuration on the C1L24VS-4PFA11F2/C is also worth cross-checking against your server and switch power cord inventory before ordering, since C13 and C19 connectors aren't interchangeable — confirm which of your rack-mount devices need C20 cords for the C19 outlets versus standard C14 cords for the C13 outlets.

For facilities standardizing on Server Technology's Smart PRO1 line across multiple racks, the C1L24VS-4PFA11F2/C (often searched as C1L24VS 4PFA11F2/C) keeps outlet architecture consistent cabinet to cabinet, which simplifies spares planning and reduces the number of distinct PDU part numbers your team has to track.

Frequently Asked Questions

Q: How many outlets does the C1L24VS-4PFA11F2/C have?

A: 24 total — 18x IEC C13 outlets and 6x IEC C19 outlets.

Q: Does the C1L24VS-4PFA11F2/C take up rack space?

A: No. It's a 0U form factor, meaning it mounts in the rack's vertical rear channel without consuming any horizontal rack units.

Q: Is the C1L24VS-4PFA11F2/C a standalone PDU?

A: It's designated an expansion unit for the Smart PRO1 series, intended to add outlet capacity to an existing Smart PRO1 deployment.

Q: What kind of power cords do I need for the C1L24VS-4PFA11F2/C outlets?

A: The 18 C13 outlets take standard C14 power cords; the 6 C19 outlets require C20 power cords. Confirm your server and switch cord types before ordering.

The C1L24VS-4PFA11F2/C is a 0U expansion unit, which tells you exactly where it belongs in a design: bolted to the rear rail of a cabinet that's already tight on rack units and needs more outlet capacity without sacrificing a slot for compute.

Technical Highlights:

• 18x IEC C13 + 6x IEC C19: a mixed outlet bank that covers standard 1U/2U server and switch loads on the C13 side while reserving six C19 positions for higher-draw chassis gear — you don't have to run a second strip for blade servers or larger switches.
• 24 outlets on one unit: that's enough density to power a fully loaded standard rack from a single expansion module rather than daisy-chaining multiple lower-count strips.
• 0U form factor: zero rack units consumed — outlet capacity scales independent of your U budget, which matters most in colocation or leased-space environments where every U has a dollar figure attached.

Deployment Considerations:

• This is an expansion unit for the Smart PRO1 line — confirm it's being added to a compatible Smart PRO1 primary PDU deployment rather than specified as a standalone unit.
• Mixed C13/C19 outlets mean cord planning matters: audit which rack devices need C20 cords for the C19 positions before the install, not after gear shows up on-site.

Where the C1L24VS-4PFA11F2/C earns its spot is a colocation cabinet or dense network closet already running a Smart PRO1 primary strip that's run out of outlets — bolt this on the rear rail and you've added 24 more C13/C19 positions without giving up a single U of usable rack space.
