Server Technology C2SG36TE-4PAE2M66 22.0kW 3-Phase Switched Outlet-Metered Rack PDU

Overview

The Server Technology C2SG36TE-4PAE2M66 is a 3-phase, 400V input Smart POPS rack PDU built for data center racks that need outlet-level power data without guessing at load balance across phases. Rated for 22.0kW at a 32A input current, it feeds 36 total outlets — 24x C13 and 12x HDOT Cx — through a 32A IEC 60309 3P+N+PE 6Hr plug. This is a PRO2 HDOT platform unit, meaning every outlet reports individually through POPS (Per-Outlet Power Sensing), and the whole unit reports inlet-level draw through PIPS (Per-Inlet Power Sensing). For colocation and hyperscale racks running mixed C14/C20 loads off one strip, the C2SG36TE-4PAE2M66 removes the need to guess which outlet is overloaded during a capacity review.

Key Features

• HDOT Cx Hybrid Outlets (12x): Cx outlets are UL-tested to accept both C14 and C20 plugs on the same receptacle, so a rack with mixed 10A and 16A device cords doesn't need two different PDU models — one strip handles both.
• 24x C13 Outlets rated <=10A @230V L-N: Standard density for servers, switches, and network gear pulling sub-10A loads — the bulk of typical rack hardware.
• Per-Outlet Power Sensing (POPS): Reports current (A), voltage (V), power (W), apparent power (VA), crest factor, power factor, and energy at every individual outlet — useful when billing colocation tenants by actual draw rather than circuit allocation.
• Per-Inlet Power Sensing (PIPS): Same measurement set at the inlet level, so you can catch a developing overload at the circuit before it cascades to a tripped breaker.
• Branch Circuit Monitoring with 2-pole 20A Breakers: Each branch is monitored independently with SNMP alerting on high usage — you get a warning before a breaker trips, not a post-mortem after a rack goes dark.
• Branch Circuit Protection (UL 489 / UL 248): Meets UL and IEC 62368-1 branch protection requirements via magnetic-hydraulic breakers, satisfying code requirements integrators are held to on data center builds.
• Hot-Swap Network Card with Star Multi-Linking: Links up to four power circuits under one IP address, and if the Primary unit loses power, the Linked unit keeps network access alive — you don't lose remote visibility into the rest of the chain during a partial outage.
• Temperature/Humidity Monitoring (2x 4P4C inputs): Accepts two external 10ft probes with SNMP alerts and email notification — worth wiring into hot-aisle/cold-aisle monitoring rather than relying on room-level sensors alone.
• Auto-Flip Current Display: LED readout cycles per-phase current automatically, so a technician doing a visual load check on a three-phase unit doesn't need a laptop to spot an unbalanced phase.
• 1% Measurement Accuracy (Voltage/Current, Input and Output): Input and output measurement accuracy both hold to +/-1% (branch-level accuracy is +/-3%), tight enough for capacity planning models that assume metered PDU data is trustworthy.
• 10/100/1000 Mbps Ethernet + RS-232 Serial: Gigabit management plus a serial fallback path, with HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, and LDAP(S) all supported — fits into environments standardizing on LDAP-based access control for infrastructure devices.
• Operating Range 0°C to 60°C, 6,500ft Elevation: The extended thermal range and altitude rating support edge and telecom sites as well as standard data center floors, not just climate-controlled white space.

Integration & Compatibility

The C2SG36TE-4PAE2M66 (often searched as C2SG36TE 4PAE2M66) is part of the Server Technology PDU catalog, specifically the PRO2 HDOT line built for 11.0kW-22.0kW / 36-42 outlet configurations. It fits alongside other rack-mounted infrastructure in data center and colocation deployments where per-outlet billing or capacity accountability matters. Network management runs over standard protocols (SNMP, SSH, HTTP(S)) so it integrates into existing DCIM tooling without a proprietary agent. For planning rack power budgets alongside networking gear, see the PoE and power planning guide — while this unit isn't a PoE injector, the same load-balancing logic applies to three-phase branch circuit planning. Pair it with rack mounting accessories appropriate for a 70in vertical strip, and consult the data center infrastructure category for compatible monitoring and cooling gear.

Frequently Asked Questions

Q: What's the total outlet count on the C2SG36TE-4PAE2M66?

A: 36 outlets total — 24x C13 (rated <=10A @230V L-N) and 12x HDOT Cx hybrid outlets (rated <=16A @230V L-N) that accept both C14 and C20 plugs.

Q: What input power does this PDU require?

A: 400V 3-phase input at 32A rated current, terminating in a 32A IEC 60309 3P+N+PE 6Hr plug, for a total capacity of 22.0kW.

Q: Does the C2SG36TE-4PAE2M66 support per-outlet power monitoring?

A: Yes. It includes POPS (Per-Outlet Power Sensing), reporting current, voltage, power, apparent power, crest factor, power factor, and energy at each individual outlet, plus PIPS (Per-Inlet Power Sensing) at the inlet level.

Q: What network protocols does the management card support?

A: HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, and LDAP(S), over a 10/100/1000 Mbps Ethernet interface, with an RS-232 serial port as a secondary access path.

Q: What's the operating temperature range?

A: 0°C to 60°C with 8%RH to 90%RH non-condensing humidity, rated to 6,500ft elevation — suited to both standard data center floors and less climate-controlled edge sites.

Q: Can I link multiple C2SG36TE-4PAE2M66 units under one IP address?

A: Yes. Star Multi-Linking allows up to four power circuits to be linked under a single IP address, with the Primary unit's Expansion PDU providing backup power to the network card if the Primary loses power.

Ted Perry

What gets my attention on the C2SG36TE-4PAE2M66 is the outlet mix: 24x C13 plus 12x HDOT Cx hybrid outlets on one 36-outlet strip. That Cx outlet accepting both C14 and C20 plugs means you're not stuck ordering a second PDU variant when a rack has a couple of higher-draw devices mixed in with standard servers.

Technical Highlights:

• 22.0kW at 400V / 32A 3-phase input: That's enough headroom for a dense rack running mixed compute and network gear without derating concerns at typical data center loads.
• POPS + PIPS dual-level metering at +/-1% accuracy: You get outlet-level and inlet-level readings both accurate to within 1%, which is tight enough to trust for tenant billing or capacity models — branch-level accuracy runs +/-3%, still fine for overload alerting.
• 2-pole 20A branch breakers with SNMP alerting: Branch circuit monitoring flags high usage before a breaker trips, which beats finding out about an overload when the rack goes dark.

Deployment Considerations:

• The 70in height means this is a full vertical zero-U strip — plan cable management and rack depth clearance before ordering, especially in high-density cabinets with already-tight PDU-to-rail spacing.
• Branch interrupt rating is 10kAIC in North America but drops to 5kAIC rest-of-world — confirm which rating applies before speccing it against local electrical code if this is going outside North America.

This is the right call for a colocation cage or hyperscale row where you need per-tenant or per-rack billing data down to the outlet, and where a mixed C13/C20 device population means a single fixed-outlet-type PDU won't cover the rack without a second unit.
