Server Technology C2S39CS-2CBA2S333 30A Switched Rack PDU

Overview

The Server Technology C2S39CS-2CBA2S333 is a PRO2 series switched power distribution unit built for data center and server room racks that need metered, remotely switchable power at 208V. This unit is rated for 30A input on a 2-phase configuration, terminated with an L6-30P locking plug — the standard connector for 208V 3-wire circuits in North American commercial facilities. For architects speccing rack power alongside networking gear and recording infrastructure, the C2S39CS-2CBA2S333 fits environments where outlet-level control and circuit accountability matter more than raw simplicity.

Key Features

• 208V Input Voltage: Matches standard commercial data center circuits, letting you standardize rack power across a facility without stepping voltage up or down at the rack.
• 2-Phase Configuration: Balances load across two phases rather than pulling everything off a single leg — reduces the chance of tripping a breaker when racks are dense with switches, recorders, and servers.
• 30A Amperage Rating: Enough headroom for a fully loaded rack of network switches and storage without derating concerns on lighter loads, while still respecting the continuous-load math (24A continuous draw under the standard 80% rule) integrators plan against.
• L6-30P Plug Type: A locking NEMA plug that won't walk out of the receptacle under vibration or cable strain — worth specifying over a straight-blade plug in any rack that gets moved, serviced, or lives near HVAC vibration.
• PRO2 Platform: Part of Server Technology's PRO2 smart PDU line, positioned for facilities that need outlet-level intelligence rather than a passive power strip.

Integration & Compatibility

Because the C2S39CS-2CBA2S333 terminates in an L6-30P, confirm your rack's upstream receptacle or whip is wired for a matching L6-30R before ordering — mismatched locking connector types are the most common return reason on 208V PDUs. This is a rack-infrastructure component, not a networked device you'd configure inside a VMS — it belongs on the power layer supporting whatever IP cameras, NVRs, and switches your rack carries. When you're planning a build-out, pair PDU selection with your PoE and power planning so amperage budgets across the rack are accounted for before hardware ships. For the broader lineup, the Server Technology catalog includes other PRO2 configurations at different voltage, phase, and plug combinations if 208V 2-phase 30A isn't the exact match your circuit calls for.

Frequently Asked Questions

Q: What input voltage does the C2S39CS-2CBA2S333 run on?

A: 208V.

Q: Is the C2S39CS-2CBA2S333 single-phase or multi-phase?

A: It's a 2-phase unit, distributing load across two phases rather than a single leg.

Q: What's the amperage rating on the C2S39CS-2CBA2S333?

A: 30A.

Q: What plug type does the C2S39CS-2CBA2S333 use?

A: An L6-30P locking plug.

Q: Will the C2S39CS-2CBA2S333 (sometimes searched as C2S39CS 2CBA2S333) work with a standard 208V L6-30R receptacle?

A: Yes — the L6-30P plug is designed to mate with an L6-30R receptacle or whip; confirm your upstream circuit is wired accordingly before install.

The C2S39CS-2CBA2S333 is a straightforward spec once you know how to read Server Technology's model string: 208V input, 2-phase, 30A, L6-30P termination. I get asked about this unit mostly from integrators racking out switch stacks and recording gear who need to know if their existing whip matches before they order.

Technical Highlights:

• 208V / 2-Phase: Splitting load across two phases instead of one leg gives you more breathing room before you're near the 24A continuous-load ceiling on a 30A circuit.
• 30A Rated / L6-30P: The locking plug is the detail people skip — a straight-blade NEMA plug can back out under cable tension in a dense rack; the L6-30P won't.
• PRO2 Platform: This sits in Server Technology's PRO2 family, so if 30A/208V/L6-30P isn't your exact circuit, there are sibling configurations at other voltage and amperage combinations worth checking.

Deployment Considerations:

• Verify your upstream receptacle is an L6-30R before this ships — plug/receptacle mismatches are the single most common reason these get returned.
• This is a power-layer component only; it doesn't carry resolution, compression, or analytics specs because it isn't a networked recording or imaging device.

Right fit for a server room or telecom closet build-out where you're racking switches and recorders on a 208V 2-phase circuit and need a locking-plug PDU that won't work loose during routine rack service.
