Server Technology C3W36RL-0AJE2MT4 0U Switched PDU with Per-Outlet Power Sensing

The Server Technology C3W36RL-0AJE2MT4 is a 0U vertical switched PDU built for data center racks and network closets where you need individual outlet control and real per-outlet power data without eating rack unit space. It carries 36 total outlets in a RAMLOCK HDOT layout — 18 C13 and 18 CX receptacles — on a 70-inch strip that mounts in the rear channel of the rack, leaving your 1U/2U slots for compute and network gear. This is a PIPS unit (Per-Inlet Power Sensing plus per-outlet switching and metering), so you get outlet-level on/off control and outlet-level power readings, not just a single input reading for the whole strip.

Overview

C3W36RL-0AJE2MT4 accepts 120V, 208V, 230V, or 240V input at 50/60Hz through an IEC C20 inlet, with rated input current of 16A (up to 20A on North American branch circuits) and a global input power capacity of 3.6kW (3.8kW in North America). The branch circuit breaker is rated at 16A with 10kAIC interrupt rating in North America and 5kAIC for rest-of-world installs, which sets the real ceiling for how much load you can safely stack across the outlet groups before tripping.

Key Features

• RAMLOCK HDOT outlets (18 C13 + 18 CX): RAMLOCK physically locks power cords in place, so a technician yanking a cable during rack service doesn't accidentally drop power to a neighboring server — a real concern on dense 0U strips where cords run close together.
• Per-outlet switching and metering (PIPS): each of the 36 outlets can be switched and read independently, so you can remote-cycle a hung server or measure exactly which device is driving your circuit toward the 16A branch breaker limit instead of guessing across a shared reading.
• C13 outlets rated ≤12A @ 120-240V (NA) / ≤10A @ 220-230V (global): sized for standard server and switch power supplies — check nameplate draw against this ceiling when planning outlet assignment.
• CX outlets rated ≤16A @ 120-240V (NA and global): the CX form factor accepts a broader mix of cord types at higher per-outlet current, useful for higher-draw equipment sharing the same strip as lighter C13 loads.
• Dual Gigabit Ethernet ports (10/100/1000 Mbps): gives you a redundant or daisy-chain-friendly network path for remote management — useful when the PDU sits in a rack where a single NIC failure shouldn't cut off visibility.
• Daisy chain up to 16 PDUs: a whole row of racks can be managed and monitored from a single network drop instead of running Ethernet to every strip, which cuts switch port consumption in multi-rack deployments.
• 802.11 a/b/g/n WiFi: lets you reach initial configuration or perform diagnostics without pulling a network cable to a PDU buried in a dense cabinet.
• Quiescent power draw under 10W: the switching and metering electronics themselves barely register against your capacity planning, so the PDU's own overhead won't eat into the 3.6-3.8kW you're budgeting for IT load.
• Measurement accuracy ±1% on voltage, current, active power, apparent power, and energy (±3% power factor): accurate enough to trust for capacity planning and billback/chargeback calculations rather than rough estimates.
• Protocol support — HTTP/HTTPS, TLSv1.2, SSHv2, SNMPv2c/v3, LDAPv3/LDAPS, TACACS+, RADIUS, FTP/SFTP, IPv4/IPv6: integrates with existing DCIM and network monitoring stacks and supports centralized authentication instead of local-only accounts.
• Operating range 0°C to 60°C, 8-90% RH non-condensing, up to 6,500ft elevation: rated for standard data center halls as well as warmer edge closets or elevated-altitude facilities without derating concerns inside that envelope.
• cTUVus and FCC Part 15 Class A certified (NA); TUV T-Mark, CE, RoHS, WEEE (global): covers both North American and international deployment paperwork for facilities that need documented compliance on file.

Integration & Compatibility

Console access is via RJ45, with an additional RJ45 sensor port for environmental monitoring probes and a 6P6C aux port for expansion accessories. A USB-A and USB-B pair round out local connectivity for firmware updates or direct configuration. The C3W36RL-0AJE2MT4 (often searched as C3W36RL 0AJE2MT4) fits into network video recorder and server rack deployments where surveillance infrastructure shares cabinet space with switching gear — pair it with a PoE switch lineup for camera drops and consult a PoE planning guide when budgeting combined IT and camera load across a rack. Browse the full Server Technology catalog for companion 0U and horizontal PDU models, and see the broader power distribution units category for rack-height alternatives if 0U vertical mounting doesn't fit your cabinet.

Frequently Asked Questions

The outlet count is what jumps out on the C3W36RL-0AJE2MT4 — 36 total across 18 C13 and 18 CX, all individually switched. That's a meaningful outlet density for a single 0U strip, and it changes how you plan a rack elevation.

Technical Highlights:

• Per-outlet metering at ±1% accuracy: on a strip with 36 loads sharing a 16A branch breaker, knowing exactly which outlet is drawing what matters more than an aggregate reading — you can rebalance load before you trip a breaker instead of after.
• 16A branch breaker with 10kAIC (NA) interrupt rating: that's your real capacity ceiling regardless of the 3.8kW North American power capacity figure — plan outlet assignment against the breaker, not just the headline wattage.
• Dual GbE plus 16-unit daisy chain: a row of C3W36RL-0AJE2MT4 units can share management traffic on one network drop, which matters when you're deploying multiple 0U strips across adjacent racks and don't want to burn a switch port per PDU.

Deployment Considerations:

• RAMLOCK outlets add a physical cord-retention step during install — budget a little extra time per cord versus a standard IEC receptacle, but it pays off the first time someone brushes a cord during hot-aisle work.
• The C13/CX current ratings differ (12A NA vs 16A NA per outlet) — don't assume uniform per-outlet capacity when spec'ing equipment placement across the strip.

This is a strong fit for a colo or enterprise data center row standardizing on 0U vertical PDUs with per-outlet visibility for chargeback reporting, particularly where mixed C13/C14 and CX cord equipment shares the same cabinet.
