CyberPower 3-PHASE Switched MBO PDU 50A 208V 24XC13/6XC19 CS8365C - PDU83107

CyberPower PDU83107 3-Phase Switched MBO Rack PDU

Overview

The CyberPower PDU83107 is a 3-phase switched metered-by-outlet (MBO) PDU rated at 50A, 208V — built for high-density data center and server room environments where per-outlet power switching and real-time current and voltage visibility are non-negotiable requirements. With a CS8365C input plug, 24 C13 and 6 C19 output receptacles, and a zero-rack-unit (0U) vertical form factor, the PDU83107 fits directly into a standard rack cabinet upright channel without consuming a single rack unit of equipment space. If you're deploying blade chassis, high-density compute, or surveillance server stacks on three-phase power, this is the PDU architecture to evaluate.

Key Features

• 3-Phase 50A/208V Input (CS8365C Plug): Three-phase delivery at 50A and 200–240V means you're distributing load across all three legs — reducing branch circuit imbalance and giving you more usable amperage per rack compared to a single-phase 30A feed. The CS8365C plug is a commercial standard for 3-phase twist-lock connections; verify your facility's panel configuration before ordering.
• 30 Total Outlets — 24×C13 + 6×C19: Twenty-four C13 receptacles handle standard 1U servers, switches, and KVM units, while the six C19 outlets cover higher-draw devices — blade servers, large UPS bypass loads, or GPU compute nodes that require the larger IEC connector. Getting the right C13/C19 ratio per rack eliminates the need for outlet adapters that add failure points.
• Switched Outlet Control (MBO): Every outlet can be individually switched on or off from the network — remotely power-cycle a locked-up server without rolling a tech to the floor, enforce sequenced power-on for boot-order-sensitive stacks, and shed non-critical loads during capacity events. For surveillance deployments, this means a camera NVR or video server can be rebooted from a NOC without dispatching a technician to a remote equipment room.
• Per-Outlet Current and Voltage Monitoring: Real-time current and voltage data is exposed at the outlet level, not just at the input. This is the distinction between a metered PDU (input only) and a metered-by-outlet PDU — you see exactly which device is drawing how much, enabling charge-back reporting, anomaly detection, and overload prevention before a breaker trips.
• LCD Display: The front-panel LCD provides local current and voltage readings without requiring a laptop or network connection. Useful during initial commissioning or when network access to the PDU isn't yet established.
• Dual RJ-45 Network Ports + USB: Two Ethernet ports support daisy-chain network topologies, letting you manage multiple PDUs on a single IP drop — a meaningful wiring simplification in dense deployments. The USB port supports firmware upgrades without network access, keeping update procedures available even during network maintenance windows.
• Broad Protocol Support: The PDU83107 supports SNMPv1/v3, HTTPS, SSH, SSL, LDAP(S), RADIUS, and Windows Active Directory integration. SNMPv3 with encryption and RADIUS/LDAP support means this PDU fits into enterprise security postures — not just basic network monitoring. IPv4 and IPv6 are both supported, covering dual-stack environments.
• 3-Meter Power Cord: The 3m (approximately 9.8 ft) cord provides enough reach to connect to overhead power whips or floor-level PDPs in most standard rack installations without requiring extension hardware.
• Firmware Upgradeable via USB: Field firmware updates via USB port eliminate dependency on live network connectivity during maintenance. Keep the PDU current with security patches and feature additions without scheduling network downtime.
• 0U Vertical Mounting: Zero rack units consumed by the PDU itself — all 30 outlets are accessible from the vertical channel. In a 42U cabinet, that's 42U available for revenue-generating equipment rather than power distribution hardware.

Integration & Compatibility

The PDU83107 integrates with SNMP-based data center infrastructure management (DCIM) platforms via SNMPv1 and SNMPv3, and supports Syslog for event forwarding to SIEM systems. Windows Active Directory integration via LDAP(S) and RADIUS allows IT teams to manage PDU credentials through existing directory infrastructure rather than maintaining a separate local account database. CLI access (Telnet and SSH) provides scripting-friendly control for automation workflows. Syslog and SMTP email alerting round out the notification stack for ops teams managing alerts outside a dedicated DCIM console.

For power distribution and UPS deployments in surveillance-heavy server rooms, the switched outlet capability pairs directly with network video recorders and video management servers — enabling remote reboot of recording infrastructure without physical access. Pair with a compatible rack cabinet that supports vertical PDU channels for a clean 0U installation.

Frequently Asked Questions

Q: What input plug does the PDU83107 use?

A: The PDU83107 uses a CS8365C input plug, which is a standard NEMA 3-phase twist-lock connector rated for the 50A, 208V three-phase input. Confirm your facility's power distribution panel includes a compatible CS8365C or CS8365 receptacle before deployment.

Q: How many outlets does the PDU83107 have, and what types?

A: The PDU83107 provides 30 total IEC 320 outlets: 24 C13 receptacles for standard servers and networking gear, and 6 C19 receptacles for higher-draw equipment such as blade chassis or GPU compute nodes.

Q: What is the difference between a metered PDU and the PDU83107's metered-by-outlet (MBO) capability?

A: A standard metered PDU monitors current and voltage only at the input — you see total load, not per-device load. The PDU83107 is metered-by-outlet, meaning current and voltage are monitored at each individual outlet. This enables per-device power accounting, early anomaly detection, and charge-back reporting by tenant or rack position.

Q: Does the PDU83107 support remote outlet switching?

A: Yes. The PDU83107 is a switched PDU, meaning each outlet can be individually turned on or off via the network management interface. This supports remote server power-cycling, sequenced power-on procedures, and load shedding without physical access to the rack.

Q: What network management protocols does the PDU83107 support?

A: The PDU83107 supports SNMPv1, SNMPv3, HTTPS, SSH, SSL, LDAP(S), RADIUS, Windows Active Directory, Syslog, CLI, FTP, SMTP, NTP, DHCP, DNS, Telnet, IPv4, and IPv6.

Q: Can the PDU83107 firmware be updated in the field?

A: Yes. Firmware is upgradeable via the onboard USB port, so updates can be applied without requiring live network connectivity to the PDU management interface.

The PDU83107 is the model I recommend when a deployment is hitting the ceiling on single-phase amperage and needs per-outlet visibility and control. The combination of 50A three-phase input via CS8365C, 30 IEC outlets split 24xC13/6xC19, and full MBO monitoring gives data center and surveillance server room operators actual per-device accountability — not just a single input current reading that tells you the rack is at 80% but nothing about which device is responsible.

Technical Highlights:

• 3-Phase Load Distribution: At 50A across three phases (200–240V), the PDU83107 lets you distribute load across all three legs of a three-phase panel — the per-phase current draw is significantly lower than an equivalent single-phase circuit, which directly reduces the risk of nuisance tripping on branch breakers in dense racks.
• SNMPv3 + LDAP(S)/RADIUS: Enterprise protocol stack is complete — encrypted SNMP polling, directory-authenticated management accounts, Syslog integration, and SSH CLI. This PDU fits into a hardened NOC environment without requiring a firewall exception for unencrypted management traffic.
• Dual RJ-45 Network Daisy-Chain: The two Ethernet ports allow multiple PDUs to share a single IP address drop via daisy-chain topology. In a multi-cabinet aisle deployment, this can eliminate individual network patch runs to each PDU — meaningful labor savings on large rollouts.

Deployment Considerations:

• Verify CS8365C receptacle availability at the power distribution panel before ordering. Three-phase 50A twist-lock terminations are not universal in all facilities — some older data centers have CS8265 (30A) or non-twist-lock three-phase panels that require an electrician's intervention before this PDU can be installed.
• The 0U form factor requires a rack cabinet with a dedicated vertical PDU mounting channel. Standard 19-inch two-post or open-frame racks may not have this channel — confirm your cabinet model supports vertical 0U PDU installation before deployment.

The PDU83107 is the right fit for high-density surveillance server rooms and compute racks that have already migrated to three-phase panel power and need individual outlet-level control and monitoring — particularly where remote NOC reboot of video management servers or NVR appliances is a hard operational requirement.
