Server Technology C2S48TE-DFME2M99 3-Phase Switched Metered Rack PDU

Overview

The Server Technology C2S48TE-DFME2M99 is a PRO2 series smart rack PDU built for high-density data center cabinets that need granular power visibility without adding a second unit of rack space per power zone. It runs on a 208V, 3-phase, 50A input through a CS8365 3P+G plug, delivering up to 14.4kW of usable capacity across 48 total outlets — 30 C13 and 18 Cx receptacles. If you're populating a cabinet with mixed server and network gear pulling variable current per phase, C2S48TE-DFME2M99 gives you outlet-level and branch-level data to catch imbalance before it trips a breaker.

Key Features

• Per-Inlet Power Sensing (PIPS): Monitors current (A), voltage (V), real power (W), apparent power (VA), crest factor, power factor, and energy at the inlet — the data you need to right-size UPS and generator capacity instead of guessing from nameplate ratings.
• HDOT Cx Outlets: 18 of the 48 outlets are UL-tested hybrid Cx receptacles that accept both C14 and C20 plugs, so a cabinet with a mix of standard and high-draw C19 cords doesn't need two different PDU outlet types.
• Branch Current Monitoring: Tracks current at each of the 2-pole, 20A branch circuit breakers and fires SNMP alerts before a branch gets close to its trip point — useful when techs add gear to a live cabinet without checking existing load first.
• Auto-Flip Current Display: Onboard LEDs cycle current per phase automatically, giving a tech standing at the rack a fast read on phase balance without pulling up the web interface.
• Alternating-Phase Outlet Layout: Distributes the three phases across the outlet strip in sequence, which shortens the power cord runs needed to balance load and keeps cable clutter down in the rear of the cabinet.
• Star Multi-Linking: Links up to four power circuits under a single IP address — a 48-outlet, 14.4kW unit like this doesn't need its own subnet entry or extra switch port just to report status.
• Hot-Swap Network Card: If the Primary unit loses power, a Linked/Expansion unit keeps the network card alive, so remote monitoring doesn't go dark during a partial outage.
• Temperature/Humidity Monitoring: Accepts two external 10-foot probes and pushes SNMP alerts and email notifications when a cabinet drifts outside the 8%RH–90%RH operating humidity or ambient temperature range you set.
• Branch Circuit Protection: Uses UL 489-rated magnetic-hydraulic breakers rated at 10 kAIC interrupt capacity — meeting the UL 62368-1 branch protection requirement rather than relying on fuses that need physical replacement after a fault.
• High Retention Locking Outlets: Reduces accidental disconnects in cabinets where cords get bumped during hot-aisle maintenance.
• Gigabit Ethernet Management: A 10/100/1000 Mbps interface plus RS-232 serial gives you both network and out-of-band console access for initial provisioning or recovery if the network path is down.

Integration & Compatibility

C2S48TE-DFME2M99 (often searched as C2S48TE DFME2M99) speaks HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, and LDAP(S), so it drops into an existing DCIM or network monitoring stack without a proprietary management layer. The RJ-12 link port ties into rack PDU and power distribution deployments where multiple PRO2 units share a single management IP through Star Multi-Linking. Rated for 0°C to 60°C operation and elevations to 6,500ft, it holds up in edge closets and non-climate-optimized spaces, not just a conditioned data hall — worth checking against your power and infrastructure planning guide before finalizing rack elevations. At 80 inches tall and 2.2 x 2.5 inches in cross-section, this is a full-height 0U vertical PDU meant for the rear rail of the cabinet, not a horizontal 1U/2U slot — confirm your cabinet's vertical mounting channel depth before ordering. Pair it with rack-mount network video recorders or server compute in the same cabinet where 3-phase load balancing across 48 outlets matters most, and coordinate power zone planning with your network switch and infrastructure layout so PDU IP addressing lines up with existing management VLANs.

Frequently Asked Questions

Q: What input voltage and plug does the C2S48TE-DFME2M99 use?

A: It runs on 208V 3-phase input rated at 50A, terminating in a CS8365 3P+G plug, with a 40A rated input current and 14.4kW input power capacity.

Q: How many outlets does the C2S48TE-DFME2M99 have and what type?

A: It has 48 total outlets: 30 C13 outlets rated up to 12A @208V L-L and 18 Cx (HDOT hybrid C13/C19) outlets rated up to 16A @208V L-L.

Q: Does the C2S48TE-DFME2M99 support remote power monitoring?

A: Yes. It includes Per-Inlet Power Sensing and branch current monitoring, with network access via 10/100/1000 Mbps Ethernet and RS-232 serial, supporting HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, and LDAP(S).

Q: What is the operating temperature range for the C2S48TE-DFME2M99?

A: It's rated for 0°C to 60°C operation and 8%RH to 90%RH humidity, at elevations up to 6,500ft.

Q: What certifications does the C2S48TE-DFME2M99 carry?

A: It's listed to UL 62368-1 and CSA C22.2 No. 62368-1, and complies with FCC Part 15 Class A and CAN ICES-003 Class A.

Q: Can multiple C2S48TE-DFME2M99 units share one IP address?

A: Yes, via Star Multi-Linking the PRO2 platform links up to four power circuits under a single IP address, with the Primary Expansion PDU providing backup power to the network card.

The spec that stands out on the C2S48TE-DFME2M99 is the split outlet layout: 30 C13 plus 18 HDOT Cx receptacles on one 48-outlet strip. That's a deliberate hedge for cabinets that mix standard 1U servers with switches or storage nodes pulling C19-class current — you're not stuck ordering a second PDU variant when one rack has both.

Technical Highlights:

• 14.4kW at 208V/50A input: Sized for a genuinely dense cabinet — run the math against your actual nameplate draw before assuming headroom, since the branch breakers are only rated 20A per 2-pole circuit.
• Per-Inlet Power Sensing: Reports crest factor and power factor per inlet, not just amps — that level of detail matters when you're reconciling PDU-reported load against UPS runtime calculations.
• 10 kAIC interrupt rating on branch breakers: UL 489 magnetic-hydraulic breakers at this rating are built to clear a fault without becoming the failure point themselves — relevant in a shared cabinet where one server's PSU fault shouldn't take down neighboring branches.

Deployment Considerations:

• This is a vertical 0U unit at 80 inches tall — measure your cabinet's rear vertical channel before ordering, not just rack unit count, since it doesn't consume horizontal 1U/2U space.
• The 40A rated input current against a 50A plug means there's a margin built in, but don't plan a cabinet's total load assuming you can run continuously at the plug's full 50A rating — size to the 40A rated figure.

Specify the C2S48TE-DFME2M99 for a 3-phase colocation or enterprise data center cabinet where you're running mixed C13/C19 gear and need per-branch alerting before a breaker trips — not for a single-phase edge closet, where a simpler 1-phase unit is the better fit.
