Server Technology C3WG36RL-2CJE2MT4 0U Switched POPS PDU with Per-Inlet and Per-Outlet Metering

Overview

The C3WG36RL-2CJE2MT4 is a 0U vertical rack PDU built for data center and colocation racks that need outlet-level power accountability, not just a branch-circuit total. It's a member of the PRO3X Switched POPS line, drawing 208V through a NEMA L6-30P plug rated 30A (24A continuous), and delivering up to 5.0kW of usable input capacity to 36 total outlets. If you're speccing power for a mixed rack of servers, switches, and storage nodes where you need to prove which device pulled how much power, this is the class of PDU to be looking at, and the C3WG36RL-2CJE2MT4 sits toward the higher-density end of that family.

Key Features

• 18x IEC 60320/C13 + 18x HDOT Cx outlets: the Cx outlet is a UL-tested hybrid that physically accepts both C14 and C20 plugs, so you're not stuck guessing plug type when racking mixed equipment — one outlet bank handles both standard servers and higher-draw gear without an adapter.
• RamLock locking outlets: a mechanical lock secures C14 and C20 plugs in place, which matters in 0U vertical mounts where cable weight and rack vibration can walk a standard plug loose over months of uptime.
• Per-Outlet Power Sensing (POPS): current, voltage, watts, VA, crest factor, power factor, and energy are metered at every individual outlet — useful when you're billing colocation tenants by actual draw or chasing down which specific device is spiking a circuit.
• Per-Inlet Power Sensing (PIPS): the same metering set applied at the inlet level, giving you a real-time read on total load against the 5.0kW capacity before a breaker trips.
• Branch Current Monitoring with UL489 breakers: 2-pole, 20A trip circuit breakers rated <=16A with 10kAIC interrupt capacity (North America), and the PDU monitors current at each breaker branch, pushing SNMP alerts before a branch gets close to tripping — the kind of early warning that avoids an unplanned outage during a capacity crunch.
• Outlet-rated headroom: C13 outlets are rated <=12A @208V L-L (15A peak) and Cx outlets <=16A @208V L-L (20A peak), giving you defined peak tolerance for equipment with inrush current spikes at power-on.
• Multi-unit linking and cascading: daisy-chain up to 16 PDUs from a single primary unit over USB or Ethernet, so a row of racks reports back through one IP address instead of provisioning network drops to every PDU individually.
• Hot-swappable controller: the intelligence, display, and connectivity ports live in a replaceable controller module, so a controller fault doesn't take the whole PDU (or the loads plugged into it) offline for a full unit swap.
• Environmental monitoring: supports up to 12 daisy-chained DX2-series SmartSensors for temperature and humidity, with SNMP alerts and email notifications when a rack drifts outside range — this unit ships with 2 sensor ports for direct connection.
• Multi-color LCD: local, at-a-glance readout of power usage, alerts, and alarms without needing to pull up the web interface during a walkthrough.
• Network protocol breadth: HTTP/HTTPS, TLSv1.2, SSHv2, Telnet, SNMPv2c/v3, IPv4/IPv6, LDAPv3/LDAPS, RADIUS, and FTP/SFTP are all supported, which covers most enterprise authentication and monitoring stacks without a middleware translator.

Integration & Compatibility

Connectivity includes a 10/100/1000 Mbps Ethernet port, RS-232 serial, an RJ-12 link port for daisy-chaining, a 6P6C auxiliary port, an RJ45 console port, and both USB-A and USB-B ports for local management and chaining. This spread of ports means the C3WG36RL-2CJE2MT4 fits into existing out-of-band management setups — SNMP polling into a DCIM platform, LDAPS/RADIUS against your existing directory, or straight SSH for scripted control — without adapters or protocol gateways. Physically, the unit measures 70.0in tall by 2.2in wide by 2.5in deep, built for 0U vertical mounting along the rear rail, and is rated for operation from 0°C to 60°C at up to 6,500ft elevation, with 8%RH to 90%RH non-condensing humidity tolerance — wide enough margin for most conditioned data center floors and many edge closets. It carries UL 62368-1, CSA C22.2 No. 62368-1, FCC Part 15 Class A, and CAN ICES-003 Class A certification. For rack planning around this PDU, review network video recorders and switching gear that will share the same power budget, and pair it with PoE switches where applicable. See the broader Server Technology catalog and the power distribution category for related capacity tiers, and consult a power and PoE planning guide when sizing total rack load across multiple PDUs.

Frequently Asked Questions

Q: What input voltage and plug does the C3WG36RL-2CJE2MT4 require?

A: It requires a 208V circuit and terminates in a NEMA L6-30P plug, rated 30A (24A continuous), delivering up to 5.0kW input capacity.

Q: How many outlets does the C3WG36RL-2CJE2MT4 have, and what types?

A: 36 total outlets: 18x IEC 60320/C13 (rated <=12A @208V L-L, 15A peak) and 18x HDOT Cx outlets (rated <=16A @208V L-L, 20A peak) that accept both C14 and C20 plugs.

Q: Does the C3WG36RL-2CJE2MT4 provide per-outlet or per-inlet power metering?

A: Both. POPS (Per-Outlet Power Sensing) meters current, voltage, power, apparent power, crest factor, power factor, and energy at each outlet, and PIPS (Per-Inlet Power Sensing) provides the same metrics at the inlet.

Q: Can the C3WG36RL-2CJE2MT4 be linked with other PDUs?

A: Yes — up to 16 PDUs can be daisy-chained from a primary unit over USB or Ethernet through a single IP address.

Q: What environmental monitoring does the C3WG36RL-2CJE2MT4 support?

A: It includes 2 built-in temperature/humidity sensor ports and supports up to 12 daisy-chained DX2-series SmartSensors with SNMP-based alerts and email notifications.

Q: What network protocols does the C3WG36RL-2CJE2MT4 support for remote management?

A: HTTP/HTTPS, TLSv1.2, SSHv2, Telnet, SNMPv2c/v3, IPv4/IPv6, LDAPv3/LDAPS, RADIUS, and FTP/SFTP.

What stands out on the C3WG36RL-2CJE2MT4 is the outlet split — 18 C13 and 18 HDOT Cx, all RamLock-secured — packed into a single 0U vertical rail. That's a real density decision, not just a spec sheet number, and it tells you this unit is meant for racks with a genuine mix of standard-draw and higher-draw equipment.

Technical Highlights:

• 5.0kW input capacity at 208V/30A (24A continuous) via NEMA L6-30P: gives you real headroom for a densely populated rack without forcing a second PDU just to cover peak load.
• Per-outlet and per-inlet metering (POPS + PIPS): both report current, voltage, watts, VA, crest factor, power factor, and energy — that's the data set you need to bill colo tenants accurately or isolate which single device is dragging a branch toward its trip point.
• UL489 2-pole 20A breakers at 10kAIC, branch-monitored: SNMP alerts fire on branch current trending high, which in practice means you get a warning email before a breaker trips mid-shift instead of finding out from a dead rack.

Deployment Considerations:

• At 70 inches tall and only 2.2 x 2.5 inches in cross-section, this is a 0U rear-rail mount — confirm your rack's vertical PDU channel clearance before ordering, especially in cabinets already running cable management in that space.
• The Cx outlets simplify plug logistics (C14 and C20 in one socket) but don't assume every device in the rack needs the 20A-peak Cx bank — match load-sensitive gear to Cx and lighter, fixed-draw devices to the C13 bank to keep breaker headroom balanced across both.

This is the right call for a colocation or multi-tenant cage where operators need itemized per-outlet billing data and want branch-level trip warnings before a shared circuit goes down — the C3WG36RL-2CJE2MT4's metering depth is built for exactly that accountability requirement.
