Server Technology C2WG12SM-0AJA2D3 Switched Per-Outlet Metered Rack PDU

Overview

The Server Technology C2WG12SM-0AJA2D3 is a 1U switched rack PDU built for data center and network closet deployments where you need to know exactly what every outlet is drawing and be able to cycle power remotely without a truck roll. It's part of the PRO2 Switched POPS line, rated for 3.3kW at 208V through a single IEC C20 input, and it puts 12 HDOT Cx outlets on a 1U chassis measuring 1.75in x 17.2in x 11.57in — a compact footprint for cabinets where rack space is already fought over. C2WG12SM-0AJA2D3 (often searched as C2WG12SM 0AJA2D3) targets colocation racks, edge closets, and any environment where per-outlet visibility and remote switching matter more than raw outlet count.

Key Features

• HDOT Cx Outlets (9x C13 + 3x C19): Cx is a UL-tested hybrid outlet that physically accepts both C14 and C20 plugs on the same receptacle. That means you're not stuck pre-planning which outlets take which cord type — a server with a C20 power supply and one with a C14 cord can sit side by side on the same strip without an adapter.
• Per-Outlet Power Sensing (POPS): Each of the 12 outlets independently reports current, voltage, power, apparent power, crest factor, power factor, and energy. When a rack starts drawing more than expected, you can isolate which device is responsible instead of guessing from a single aggregate reading.
• Per-Inlet Power Sensing (PIPS): The inlet itself is monitored the same way outlets are, giving you a check on total draw against the 16A input current rating and 3.3kW capacity before a breaker trips.
• Branch Circuit Monitoring and Protection: The unit ships with 2-pole, 20A branch circuit breakers rated for 10 kAIC interrupt capacity, monitored individually with SNMP alerts on high usage — you get a warning before a branch trips instead of finding out when a rack goes dark.
• Remote Outlet Control: Individual outlets can be switched on, off, or cycled remotely, which matters when a hung server needs a hard power cycle and the nearest hands are in a different building.
• Auto-Flip Current Display: Onboard LEDs cycle through per-phase current readings, giving techs a fast visual load check during rack walks without pulling up the web interface.
• Hot-Swap Network Card with Star Multi-Linking: PRO2 links up to four power circuits under a single IP address, and if the primary unit loses power, the linked expansion unit keeps the network card alive — you don't lose remote visibility just because one circuit dropped.
• Temperature/Humidity Monitoring: Supports two external 10ft T/H probes per unit with SNMP alerts and email notification, useful for catching a failing CRAC unit before it becomes a thermal event across the row.
• Wide Environmental Range: Rated for 0°C to 60°C operating temperature and 8%RH to 90%RH humidity, covering everything from a conditioned data hall to a less-controlled edge closet or telecom cabinet.
• Multi-Protocol Network Management: Supports HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, and LDAP(S), plus an RS-232 serial interface and 10/100/1000 Mbps Ethernet — it fits into existing DCIM and monitoring stacks rather than forcing a proprietary tool.

Integration & Compatibility

Because the C2WG12SM-0AJA2D3 speaks SNMP and standard network protocols out of the box, it integrates into existing monitoring and DCIM platforms rather than requiring a dedicated management console. The RS-232 serial port covers out-of-band access for environments where a dedicated management network isn't available yet. LDAP(S) support means outlet-control access can tie into an existing directory service rather than maintaining a separate local user list on every PDU in the rack.

Frequently Asked Questions

Q: What's the input voltage and plug type on the C2WG12SM-0AJA2D3?

A: It runs on 208V input through an IEC C20 plug, rated for 16A input current and 3.3kW capacity.

Q: How many outlets does the C2WG12SM-0AJA2D3 have and what type?

A: 12 HDOT Cx outlets total — 9x C13 and 3x C19 — each accepting either C14 or C20 plugs.

Q: Can I monitor power at the individual outlet level?

A: Yes. Per-Outlet Power Sensing (POPS) reports current, voltage, power, apparent power, crest factor, power factor, and energy for each of the 12 outlets independently.

Q: What network protocols does this PDU support for remote management?

A: HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, and LDAP(S), plus an RS-232 serial interface and 10/100/1000 Mbps Ethernet.

Q: What's the operating temperature range?

A: 0°C to 60°C with 8%RH to 90%RH humidity, covering standard data center and less-controlled edge environments.

Q: Does the C2WG12SM-0AJA2D3 support remote outlet switching?

A: Yes, it's a switched PDU — individual outlets can be turned on, off, or cycled remotely, and outlet control access can be tied to LDAP(S) for centralized user management.

What stands out on the C2WG12SM-0AJA2D3 is the outlet mix — 9x C13 and 3x C19, all HDOT Cx, so you're not stuck reshuffling gear because a new server showed up with a C20 power cord. At 3.3kW on a 208V/16A input through the C20 inlet, this is sized for a single mixed-load cabinet, not a high-density GPU rack.

Technical Highlights:

• Per-Outlet Power Sensing: All 12 outlets report current, voltage, power, VA, crest factor, power factor, and energy independently — when a rack's draw creeps up, you pull outlet-level data instead of guessing which device is the culprit.
• Branch Circuit Breakers, 10 kAIC: 2-pole 20A breakers with a 10 kAIC interrupt rating monitored individually, with SNMP alerts before a branch trips — that's the difference between a warning email and an unplanned outage.
• Star Multi-Linking: Up to four power circuits share one IP address, and the network card stays alive on the linked Expansion unit if the Primary loses power — you keep remote reach into the rack even during a partial circuit failure.

Deployment Considerations:

• The 1.75in x 17.2in x 11.57in chassis is standard 1U, but confirm your cabinet has horizontal mounting space free — this isn't a zero-U vertical PDU, so it consumes rack unit space like any other 1U device.
• Rated to 0°C-60°C and 8-90%RH, which covers most edge and telecom closets, but this is still a 208V/16A unit — verify your panel and circuit are provisioned for that before ordering, since it won't step down to 120V service.

This is the right unit for a colocation or edge cabinet running mixed C13/C19 gear off a single 208V circuit, where the operator wants per-outlet billing-grade data and the ability to remote-cycle a hung device without dispatching a technician.
