Server Technology C4G48RA-YCBE2FD8 120/208V 3-Phase 30A Switched Rack PDU

The Server Technology C4G48RA-YCBE2FD8 is a 120/208V 3-phase switched rack PDU built for data center and server room racks where you need outlet-level control and reporting without guessing at circuit load. Rated for 30A input (24A continuous) through a NEMA L21-30P plug, it delivers up to 8.6 kW of usable capacity across 24 C13 outlets and 3 NEMA 5-20R outlets — enough density to power a fully loaded rack of servers, switches, and PDU-dependent appliances from a single vertical unit.

Overview

This is a per-outlet switched PDU, meaning each of the 24 C13 outlets can be individually powered on, off, or rebooted remotely — a meaningful operational advantage when a hung server needs a hard power cycle at 2 AM and a technician isn't on-site. Dual Ethernet ports with 10/100/1000 Mbps support let you daisy-chain or provide redundant network paths for management, and the dedicated RJ45 sensor port and PDU link port extend monitoring to environmental sensors or linked units without consuming a data port. The C4G48RA-YCBE2FD8 (often searched as C4G48RA YCBE2FD8) is designed for the kind of rack where downtime has a dollar figure attached to it.

Key Features

• Per-Outlet Control: All 24 C13 outlets switch independently, so a single misbehaving PDU or server can be power-cycled remotely without touching neighboring equipment — no more walking the data center floor for a manual reboot.
• 30A Input / 24A Continuous Rating: Sized to actually use the circuit you're paying for — 24A continuous under UL/NEC derating rules translates to real usable headroom for growth, not just a nameplate number.
• 8.6 kW Input Power Capacity: Enough load capacity to run a densely populated rack of 1U/2U servers plus networking gear off one PDU, reducing the number of circuits and whips you need to pull to the rack.
• 24x C13 + 3x NEMA 5-20R Outlets: Mixed outlet types mean you're not stuck buying adapters for legacy NEMA-plug equipment alongside standard IEC-cabled servers — one PDU covers both.
• Dual Ethernet, 10/100/1000 Mbps: Gigabit-capable ports support redundant management paths or link-chaining multiple PDUs on one IP, cutting down on switch port consumption in the rack.
• RJ45 Sensor Port: Add temperature/humidity probes at the rack level without a separate monitoring appliance — useful for catching a failed CRAC unit before it becomes a thermal event.
• Quiescent Power Draw Under 7W: The PDU's own overhead is negligible against an 8.6 kW load, so it isn't eating into the capacity you're billing to the rack.
• UL 489 / CSA C22.2 No. 5 / IEC 60947-2 Branch Circuit Protection: Recognized breaker standards mean the onboard protection is rated for real fault interruption, not a cosmetic circuit breaker.
• Operating Range 0°C to 60°C: Rated well past standard data center setpoints, giving margin in poorly conditioned server rooms or edge closets without dedicated cooling.
• Compact 56mm x 64mm Cross-Section: A slim vertical profile (2032mm tall) keeps cable channel space open in 0U rack-mount deployments where every millimeter of side clearance matters.

Integration & Compatibility

The dual RJ45 network interfaces and dedicated PDU link port let the C4G48RA-YCBE2FD8 report into existing data center infrastructure management (DCIM) tooling over standard Ethernet, and multiple units can be link-chained for centralized monitoring across a row. If you're planning a new deployment, review your network video recorders and switching gear power budgets against the 8.6 kW capacity before finalizing outlet allocation, and pair this PDU with a documented PoE and power planning guide to avoid overloading a single 3-phase leg. For facilities standardizing on one power management platform, check the broader Server Technology catalog for compatible 0U and horizontal models rated for different amperage or outlet mixes.

Frequently Asked Questions

Q: What input plug does the C4G48RA-YCBE2FD8 use?

A: It terminates in a NEMA L21-30P plug rated for 30A input, with a 24A continuous current rating.

Q: How many outlets does the C4G48RA-YCBE2FD8 have?

A: It provides 24 individually switched C13 outlets plus 3 NEMA 5-20R outlets, for 27 total outlets on one unit.

Q: Can each outlet be controlled independently?

A: Yes. The C4G48RA-YCBE2FD8 supports per-outlet control, allowing individual outlets to be switched on or off remotely.

Q: What's the maximum power capacity of this PDU?

A: The input power capacity is rated at 8.6 kW at 120/208V 3-phase.

Q: What's the operating temperature range?

A: The unit is rated for operation from 0°C to 60°C with 5% to 90% RH non-condensing humidity.

Q: What's the warranty on the C4G48RA-YCBE2FD8?

A: It carries a 2-year limited manufacturer warranty.

I spec 3-phase PDUs for rack builds regularly, and the C4G48RA-YCBE2FD8 stands out for its outlet density-to-footprint ratio — 24 switched C13s plus 3 NEMA 5-20Rs in a 56mm x 64mm cross-section vertical form factor. That's a lot of controlled power in a strip that won't eat your cable management channel.

Technical Highlights:

• 8.6 kW Input Power Capacity at 30A/24A continuous: On a 208V 3-phase L21-30P circuit, that capacity covers a fully populated 42U rack of dual-PSU servers with headroom to spare — I don't recommend running any PDU at nameplate max, and this one gives you the derated 24A continuous figure up front instead of making you calculate it.
• Per-Outlet Switching on All 24 C13s: Remote power-cycling a locked-up server without a truck roll is the single biggest reason to pay up for a switched PDU over a basic metered unit.
• Dual Gigabit Ethernet + Dedicated Sensor/Link Ports: Separating the sensor and PDU-link RJ45 jacks from the management NICs means you're not fighting for a single port when you add temperature probes or chain a second unit.

Deployment Considerations:

• Confirm your panel has a matching NEMA L21-30P receptacle before ordering — this is a 3-phase plug, not a drop-in replacement for a single-phase L5-30P whip.
• The 3x NEMA 5-20R outlets are a nice touch for legacy equipment, but don't count them toward your C13-based rack power budget — they typically sit on a separate leg and should be load-balanced accordingly.

This is the right call for a colocation or enterprise data center rack running mixed IEC and NEMA-plug equipment on a 3-phase 208V circuit, where remote outlet control justifies the added cost over a basic metered strip. The C4G48RA-YCBE2FD8 is not the right fit for single-phase 120V edge closets — look at a lower-amperage single-phase model in the same family instead.
