Server Technology C3W36RL-DFJE2MT2 Switched 0U 36-Outlet Rack PDU

The C3W36RL-DFJE2MT2 is a 0U vertical switched PDU built for high-density racks that need per-outlet control and real load visibility, not just power distribution. With 18 C13 and 18 CX outlets in a RamLock retention design, rated at 14.4kW input capacity on a 208V/50A CS8365 plug, this unit targets data center and network operations center racks where remote power cycling and outlet-level monitoring justify the switched tier over a basic PDU. The model number C3W36RL-DFJE2MT2 (often searched as C3W36RL DFJE2MT2) identifies the specific outlet count, HDOT sensing, and color-matrix display configuration covered here — confirm these details against the exact SKU before ordering, since Server Technology's PRO3X line spans multiple outlet counts and plug types.

Overview

This is a 0U form factor, meaning it mounts vertically along the side of the rack rather than consuming horizontal rack units — a real consideration when every 1U or 2U of usable space in the cabinet is already spoken for by switches, servers, or patch panels. The color matrix display gives local visual status at the unit without needing a laptop or remote session for a quick load check, which matters during physical rack audits or troubleshooting a tripped breaker at 2am.

Key Features

• 18 C13 + 18 CX outlets: the CX outlets accept both C14 and C20 plugs, so mixed equipment — standard servers alongside higher-draw switches or storage arrays — shares one PDU instead of forcing a second unit into the rack.
• RamLock outlet retention: physically locks power cords into the outlet, which eliminates the accidental unplug failure mode that shows up during cable dressing or when a tech leans into a crowded rack.
• HDOT outlet-level sensing: reports current draw per outlet rather than only at the PDU input, so you can identify which specific device is spiking load without disconnecting anything to test.
• 14.4kW input power capacity at 208V: on a 50A CS8365 plug (40A rated current), this covers a genuinely dense rack — plan your circuit sizing around the 40A continuous rating, not the 50A plug rating, to stay within code.
• Outlet ratings — C13 ≤12A / CX ≤16A at 208V L-L: knowing the per-outlet ceiling (with 15A/20A peak headroom) prevents overloading a single outlet even when the PDU as a whole has capacity left.
• ≤16A branch circuit breakers, 10 kAIC interrupt rating: the breakers protect individual outlet groups so one faulted device trips a branch, not the whole PDU, and the 10 kAIC rating is what an electrical inspector will check against available fault current.
• Under 10W unloaded power draw: the PDU's own overhead is negligible against a 14.4kW load, so it isn't eating into your capacity budget.
• 10/100/1000 Mbps Ethernet plus 2 sensor ports, 1 aux, 1 console, 2 USB: gives you gigabit management connectivity alongside dry-contact or environmental sensor inputs (temperature/humidity probes) without a separate monitoring appliance.
• HTTP(S), SSH, Telnet, SNMP, FTP, SMTP, Syslog, LDAP(S), RS-232: this protocol spread covers both modern secure management (HTTPS, SSH, LDAPS) and legacy NOC tooling (SNMP polling, Syslog forwarding) so it drops into existing monitoring stacks instead of requiring new ones.
• PDU linking for up to 16 units: daisy-chain multiple PDUs under one network connection and IP address, which cuts down on switch ports and IP allocations in a multi-rack row.
• 0°C to 60°C operating range, 8–90%RH non-condensing: supports non-climate-controlled spaces — edge closets, industrial enclosures — not just conditioned data center floors.

Integration & Compatibility

The Ethernet and serial management stack lets this PDU sit on the same out-of-band network as your PoE and management switches, reporting into whatever DCIM or monitoring platform already polls SNMP or ingests Syslog. If you're speccing power for a new row of racks, pair the outlet-count math here with a broader look at power and PoE budget planning before finalizing PDU quantity per rack. For UPS-backed rack power upstream of this PDU, review compatible UPS systems sized to the 14.4kW input capacity. The Server Technology PDU catalog includes lower-outlet-count and single-phase variants if 36 outlets or 208V three-phase input doesn't match your rack's actual draw. Rack rail and PDU accessory compatibility should be confirmed against rack mounting accessories for the specific cabinet depth in use.

Frequently Asked Questions

Q: What input voltage and plug does the C3W36RL-DFJE2MT2 require?

A: It runs on 208V at 50/60 Hz through a CS8365 3P+G 50A plug, with a 40A rated input current — confirm your rack's circuit is provisioned for a 40A continuous load before install.

Q: How many outlets does the C3W36RL-DFJE2MT2 have and what plug types do they accept?

A: 36 total outlets — 18 C13 and 18 CX (CX accepts both C14 and C20 cord ends) — each with RamLock physical retention.

Q: Does the C3W36RL-DFJE2MT2 provide per-outlet power monitoring?

A: Yes, it uses HDOT outlet-level sensing to report current draw at each individual outlet, not just at the PDU input.

Q: Can multiple C3W36RL-DFJE2MT2 units be managed together?

A: Yes, the PDU supports linking up to 16 units so a multi-rack row can be managed under a single network connection.

Q: What is the operating temperature range for the C3W36RL-DFJE2MT2?

A: 0°C to 60°C with 8%RH to 90%RH non-condensing humidity, rated up to 6,500 ft elevation.

Q: What certifications does the C3W36RL-DFJE2MT2 carry?

A: UL 62368-1, CSA C22.2 No. 62368-1, FCC Part 15 Class A, and CAN ICES-003 Class A.

What stands out on the C3W36RL-DFJE2MT2 is the HDOT outlet-level sensing paired with 36 total outlets — that's a lot of individually monitored circuits on one 0U strip, and it changes how you troubleshoot a rack under load.

Technical Highlights:

• 14.4kW capacity at 208V/40A rated input: sizes comfortably for a dense compute or network rack, but size your upstream breaker to the 40A rated current, not the 50A CS8365 plug rating.
• 18 C13 + 18 CX outlet split: the CX outlets flex between C14 and C20 cord ends, so you're not stuck reordering a different PDU when a higher-draw switch shows up mid-deployment.
• RamLock retention on all 36 outlets: in racks with heavy cable churn, physically locked cords are the difference between a clean audit and a dropped circuit from an accidental tug.

Deployment Considerations:

• PDU linking tops out at 16 units — plan IP addressing and network drops for the full row before racking the first unit, since retrofitting the link chain later means re-touching cabling you've already dressed.
• The 10 kAIC interrupt rating and ≤16A branch breakers are the numbers your electrical inspector will ask for — have them ready rather than pulling the datasheet mid-inspection.

This is the right call for a NOC or colo cage running mixed C13/C20 gear where per-outlet monitoring and remote power cycling justify a switched PDU over a basic metered unit — not for a light single-server closet where a simpler PDU covers the load.
