Server Technology C3S36RL-EPJE2MT4 0U 36-Outlet Smart PDU

Overview

The Server Technology C3S36RL-EPJE2MT4 is a 0U vertical rack PDU built for data center and telecom cabinets that need branch-level visibility into power draw without sacrificing a single U of rack space. Rated for 1.9kW to 7.3kW on a 230V/32A 2P+PE input, it mixes 18 IEC 60320/C13 outlets with 18 HDOT Cx outlets for 36 total connections, giving you flexibility across mixed IT loads without guessing which cable end you'll need. This is a per-inlet power sensing (PIPS) model, meaning current, voltage, power, apparent power, crest factor, power factor, and energy are all metered at the inlet — critical data when you're chasing circuit headroom across a dense rack row. C3S36RL-EPJE2MT4 (often searched as C3S36RL EPJE2MT4) fits environments where uptime reporting isn't optional.

Key Features

• HDOT Cx Outlets (18x): Cx is a UL-tested hybrid outlet accepting both C14 and C20 plugs, so a single outlet bank handles mixed server and switch power cords without stocking separate whip types.
• C13 Outlets (18x): Standard IEC 60320/C13 connections rated at up to 10A @230V L-N — the default cord end for most 1U/2U servers and network gear.
• Per-Inlet Power Sensing (PIPS): Monitors current load, voltage, power, apparent power, crest factor, power factor, and energy at the inlet, so you can spot a circuit trending toward its limit before it trips instead of after.
• Branch Current Monitoring: Tracks current at each 2-pole, 20A trip breaker branch and fires SNMP alerts on high usage — useful for catching an overloaded branch during a rack refresh before it takes down a row.
• Branch Circuit Protection: Meets UL and IEC 62368-1 requirements via UL 489 magnetic-hydraulic breakers, rated 10 kAIC in North America (5 kAIC ROW) — real interrupt capacity, not a nameplate afterthought.
• Multi-Unit Linking & Cascading: Daisy-chain up to 16 PDUs from one primary unit over a single IP address via USB or Ethernet — cuts down on the number of management IPs and switch ports you burn per row.
• Network Monitoring Protocols: HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, LDAP(S), and RS-232 serial cover most NOC toolchains without a translation layer.
• Environmental Monitoring: Supports up to 12 daisy-chained DX2-series SmartSensors with SNMP alerts and email notifications — extend monitoring to rack-level temperature and humidity without a separate sensor network.
• Multi-Color LCD: Local display of power usage, alerts, and alarms means a tech standing at the rack doesn't need a laptop to confirm load status.
• Hot Swappable Controller: The controller houses compute, display, and connectivity — swap it without powering down the load side, which matters on a PDU carrying live production circuits.
• RamLock Locking Outlets: A mechanical lock secures C14 and C20 plugs in place, reducing accidental disconnects in high-traffic cold aisles.
• High Temperature Rating: Tested for reliable operation at up to 60°C, which covers hot-aisle containment and edge deployments running warmer than a typical data hall.

Integration & Compatibility

Connectivity includes a 10/100/1000 Mbps Ethernet port, 2x RJ45 sensor ports, 1x 6P6C auxiliary port, 1x RJ45 console port, 1x USB-A plus 1x USB-B, and 1x RJ-12 link port — enough I/O to run cascading, environmental sensors, and out-of-band console access from one unit. The 230V/32A 2P+PE input plug (6-hour rated) and 7.3kW capacity place this PDU in higher-density cabinets than a standard 208V/30A unit would support. Physically it's a 0U form factor at 70.0in tall, 2.2in wide, and 2.5in deep, designed to mount vertically along the rear rail without consuming horizontal U space — worth checking against your cabinet's rear channel clearance before ordering. Operating range is 0°C to 60°C at 8-90% RH non-condensing, up to 6,500ft elevation; storage tolerates -40°C to 85°C up to 50,000ft. For rack-wide power planning, review a PoE and power planning guide alongside your network video recorder or server deployment to size circuits correctly across the row. The Server Technology PDU catalog covers adjacent PRO4X and PRO2 families if this unit's outlet mix doesn't match your load, and a compatible PoE switch or rack mounting accessory may round out the cabinet build.

Frequently Asked Questions

Q: Does the C3S36RL-EPJE2MT4 support per-outlet or per-inlet power monitoring?

A: It uses Per-Inlet Power Sensing (PIPS), metering current, voltage, power, apparent power, crest factor, power factor, and energy at the inlet, plus branch current monitoring at each breaker branch.

Q: Can I daisy-chain multiple C3S36RL-EPJE2MT4 units together?

A: Yes — up to 16 PDUs can be cascaded from a single primary unit over USB or Ethernet, managed through one IP address.

Q: What network protocols does the C3S36RL-EPJE2MT4 support?

A: 0°C to 60°C at 8-90% RH non-condensing, up to 6,500ft elevation — the unit is tested and approved for 60°C data center environments.

James Everett

What stands out on the C3S36RL-EPJE2MT4 is the outlet mix — 18 C13 and 18 HDOT Cx across a single 0U strip, backed by per-inlet power sensing instead of an estimated load reading. On a 7.3kW/32A circuit, that's the kind of unit I spec when a rack row is running mixed 1U server and network gear off the same PDU and someone actually needs to pull energy data for capacity planning, not just a green LED.

Technical Highlights:

• PIPS Metering: current, voltage, power, apparent power, crest factor, power factor, and energy at the inlet — enough granularity to catch a branch creeping toward its 20A trip point before it actually trips.
• 36 Outlets, Two Types: 18x C13 (≤10A @230V L-N) and 18x HDOT Cx (≤16A @230V L-N, accepts both C14 and C20 plugs) — one PDU covers server and switch cord ends without a second unit.
• 60°C Operating Rating: tested for reliable operation up to 60°C, which matters if this row sits in a hot-aisle containment pod running warmer than a conventional data hall.

Deployment Considerations:

• At 70.0in tall and only 2.2in wide, this mounts 0U along the rear rail — confirm rear channel clearance on the cabinet before ordering, since it consumes zero U space but needs rear depth.
• The 230V/32A 2P+PE input plug is rated for 6-hour duty — check that your facility's input receptacle and breaker match before wiring, since this isn't a standard NEMA 5-20 drop.

I'd point this PDU at a colocation or enterprise data center cabinet running mixed server and network hardware on a single high-density circuit, where the operator needs branch-level alerting through SNMP rather than a walk-down inspection to catch an overloaded breaker. C3S36RL-EPJE2MT4 makes sense as the standard for any row where per-inlet energy reporting feeds into a capacity or billing system.
