Server Technology C4G36RA-5CBD2FE1 415V Switched POPS Rack PDU

Overview

The Server Technology C4G36RA-5CBD2FE1 is a 415V, 17.3kW switched rack PDU built for data center and colocation racks that need outlet-level power visibility, not just a total load reading. It combines Per-Outlet Power Sensing (POPS) with Per-Inlet Power Sensing (PIPS) so you get current, voltage, power, apparent power, crest factor, power factor, and energy data at both the whole-unit and individual-outlet level. This is a vertical zero-U form factor at 70 inches tall, 2.2 inches wide, and 2.5 inches deep — designed to mount in the rear channel of a rack cabinet without eating into usable U-space for servers or switches. C4G36RA-5CBD2FE1 (often searched as C4G36RA 5CBD2FE1) is positioned for hyperscale, colocation, and high-density edge deployments where 415V three-phase distribution is already in place.

Key Features

• 17.3kW input power capacity at 415V: supports high-density rack loads — GPU clusters, blade chassis, dense compute — without needing a second PDU in the same cabinet.
• NEMA L22-30P input plug, 30A input current, 24A rated: a locking three-phase plug that won't back out under vibration, with the 24A continuous rating giving you the headroom NEC 80% derating requires for a 30A circuit.
• 36 total outlets — 12x C13 and 24x HDOT Cx: the Cx outlets are UL-tested hybrids that physically accept either a C14 or C20 plug, so you're not stuck reordering PDUs when a server ships with a C19/C20 power cord instead of the standard C13/C14.
• Outlet ratings up to 16A @ 208V L-N (20A peak) on Cx, 12A @ 208V L-N (15A peak) on C13: gives you real per-outlet headroom for mixed loads — small switches on C13, higher-draw servers or storage arrays on Cx — on the same strip.
• Six branch circuit breakers, UL489 2-pole 20A trip, 10 kAIC interrupt rating: a fault on one outlet group trips its own breaker instead of taking down the whole PDU, which matters when you've got dozens of servers hanging off a single unit.
• Per-Outlet Power Sensing (POPS): per-outlet current, voltage, power, VA, crest factor, power factor, and energy — the data you need to right-size circuits and catch a single misbehaving PSU before it trips a breaker.
• Per-Inlet Power Sensing (PIPS): the same measurement set at the inlet level, useful for capacity planning across the whole rack rather than outlet-by-outlet.
• Input and output measurement accuracy of ±0.2% for both voltage and current: tight enough for real capacity billing and power-budget planning in colocation environments, not just rough load estimates.
• Hot-swappable controller: the controller — housing compute, display, and connectivity — can be replaced without powering down the outlets it manages, so a controller fault doesn't force a rack outage.
• 45-degree angled infeed: improves cable routing and strain relief in tight rear-of-rack spaces, and the bend radius is rated for 60A cords if you're standardizing infeed cabling across a row.
• Multi-unit linking and cascading, up to 16 PDUs on one IP: cuts down on IP address consumption and management overhead when you're running a full row of racks off this PDU family.
• Environmental monitoring for up to 12 daisy-chained DX2 SmartSensors: lets you tie temperature/humidity alerting into the same management interface as your power data, with SNMP alerts and email notifications.

Integration & Compatibility

Network access runs over 10/100/1000 Mbps Ethernet or 802.11 a/b/g/n Wi-Fi, with management through HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, LDAP(S), or RS-232 serial — enough protocol coverage to fit into most existing DCIM or monitoring stacks without a proprietary agent. A 5V/500mA USB output is available for auxiliary peripherals at the rack. The unit is rated for operation from 32°F to 140°F (0°C to 60°C) at 5%–90% RH non-condensing, with storage tolerance down to -40°F and up to 185°F — a wide enough band for most conditioned data center floors as well as less-controlled edge and telecom cabinets. Certifications include UL 62368-1, CSA C22.2 No. 62368-1, FCC Part 15 Subpart B Class A, and CAN ICES-003 Class A. For the rest of the rack, pair this PDU with rack-mount NVRs or compute drawing from the same 415V circuit, and review a PoE and power planning guide before finalizing circuit assignments across a multi-PDU row. Browse the full Server Technology PDU catalog for lower-capacity or single-phase variants if 415V three-phase isn't available at your site, and check the power distribution units category for outlet configurations better suited to lower-density racks. A companion rack accessory lineup covers cable management for the angled infeed if you're standardizing a full row.

The number that jumps out on the C4G36RA-5CBD2FE1 is the 17.3kW capacity off a 415V, 30A NEMA L22-30P infeed — that's a real high-density rack PDU, not a repackaged single-phase strip. I spec this class of unit when a rack is pushing dense compute or GPU nodes and the site already has three-phase 415V distribution run to the row.

Technical Highlights:

• 36 outlets (12x C13, 24x HDOT Cx): the Cx outlets accept both C14 and C20 cords, so you're not locked into a single power cord spec across a mixed rack of switches, servers, and storage.
• POPS + PIPS metering at ±0.2% accuracy: that's tight enough to actually trust for capacity billing or power-budget audits, not just a rough load gauge.
• Six UL489 branch breakers at 20A trip, 10 kAIC: outlet groups are fused independently, so one overloaded server doesn't take the whole PDU offline.

Deployment Considerations:

• Confirm your site actually runs 415V three-phase to the rack before ordering — the NEMA L22-30P infeed won't adapt to a standard 208V single-phase drop.
• At 70 inches tall and only 2.2 inches wide, this mounts in the rear vertical channel of the rack — check your cabinet's rear channel clearance against the 2.5-inch depth before ordering, especially in narrower colocation cabinets.

This is the right call for a colocation or hyperscale rack running dense, mixed-cord-type equipment on 415V power where you need outlet-level accountability for every device drawing from the C4G36RA-5CBD2FE1 — not a fit for a standard 120V/208V single-phase server room.
