CyberPower PDU41004 1U Managed Rack/Wall Power Distribution Unit
Overview
The CyberPower PDU41004 is a 1U managed power distribution unit delivering 8 individually switched IEC-320 C13 outlets across a universal 100–240 VAC input range — the right pick for mixed-voltage server rooms, NVR racks, and global deployments where a single PDU needs to work on any grid. With a derated 12A continuous draw from a C14 input plug and a full SNMPv3/HTTPS management stack, it sits above basic strip PDUs without requiring a dedicated power monitoring appliance. The 10 ft (3.0 m) input cord on a straight C14 plug routes cleanly to a rack-mounted UPS or facility C13/C14 whip without adapters.
Key Features
- Universal 100–240 VAC Input: A single PDU41004 handles both North American 120V circuits and international 230V feeds. Facilities with mixed voltage infrastructure — or integrators stocking for global deployments — can standardize on one SKU instead of maintaining separate 120V and 240V inventories.
- 8 Individually Switched IEC-320 C13 Outlets (Front-Facing): Outlet-level switching means you can power-cycle a single misbehaving NVR channel, camera encoder, or network switch port without touching adjacent equipment. All 8 outlets are front-facing, which matters in shallow or wall-mount installs where rear access is obstructed.
- 12A Derated Continuous / 15A Maximum Input: The 80% derating to 12A continuous is the correct operating ceiling for 24/7 loads — running at nameplate 15A into continuous equipment is a known failure mode this unit is designed to prevent. Plan your outlet load budget against 12A, not 15A.
- Multifunction LCD Power Control Display: On-unit metering shows real load data without needing to log into the management interface. Useful during commissioning and for on-site technicians who need a quick sanity check without pulling up a browser session.
- SNMPv3 / HTTPS Remote Management with Full Protocol Stack: The management stack covers SNMPv1/v3, HTTPS, SSH, SSL/TLS, LDAP(S), RADIUS, Syslog, and Windows Active Directory integration. That's a full enterprise credential stack — you can tie outlet control and alerts into an existing NOC without standing up separate authentication infrastructure.
- Environmental Sensor via Optional RJ45: The RJ45 universal port accepts an optional environmental sensor for temperature and humidity monitoring. If you're deploying in a wiring closet without dedicated HVAC monitoring, this turns the PDU into a dual-purpose device at minimal incremental cost.
- Modular Cascading via RJ45: Multiple units can be daisy-chained for centralized management without consuming additional IP addresses per PDU. In dense rack deployments, this simplifies SNMP polling and firmware management across a PDU fleet.
- Upgradeable Firmware: Firmware updates via FTP or the web interface mean you can patch security vulnerabilities and add protocol support without hardware replacement — relevant given the LDAP(S)/RADIUS management surface exposed on this unit.
- Flexible Mounting — Horizontal/Vertical Rackmount and Wallmount: Ships with two sets of adjustable L-brackets (short and long) supporting 1U horizontal rack, vertical rail, or direct wall mount. That range covers a standard server rack in a data center, a vertical strip in a network closet, and a flat wall-surface install in a camera head-end room without purchasing separate hardware.
- Operating Range 32–140°F (0–60°C) / 0–95% RH Non-Condensing: The 60°C upper limit is adequate for most conditioned equipment rooms but rules out uncooled attic closets in warm climates. Verify ambient temperature before installing in any space without active cooling.
- RoHS Compliant / UL62368 Safety Listed: UL62368 listing is the current audio/video/IT equipment safety standard (replaced UL60950). Relevant for insurance, facilities approval, and any AHJ inspection requiring listed equipment.
- Cord Retention and External Site Ground Pin: Factory-included cord retention tray prevents accidental disconnection from vibration or cable pull — meaningful in rack environments with heavy cable runs. The external site ground pin supports supplemental bonding where local codes require it.
Integration and Compatibility
The PDU41004 accepts an IEC-320 C14 input plug, making it compatible with the C13/C14 output receptacles found on most rack-mount UPS systems without adapters. The 8 C13 outlets directly power standard server, NVR, switch, and encoder power supplies. The SNMP management interface integrates with Nagios, PRTG, SolarWinds, and any NMS capable of SNMPv1/v3 traps. The RADIUS and LDAP(S) support connects to Active Directory or FreeRADIUS for role-based outlet access control. Windows AD integration is explicitly listed in the protocol stack, which is relevant for enterprise IT teams managing PDUs within existing directory policy.
For deployments requiring per-outlet energy metering rather than aggregate input metering, verify the PDU41004's display and SNMP OID coverage against your monitoring requirements — the spec sheet references Power Control Display and LED indicators (Tx/Rx, Link, Normal/Warning/Critical) but does not specify per-outlet current sensing at the datasheet level. If per-outlet kWh billing or granular outlet-level amp monitoring is a hard requirement, evaluate against models in the CyberPower PDU lineup with explicit per-outlet metering specifications.
Within the CyberPower managed PDU family, the PDU41004 is the universal-voltage 1U 8-outlet variant. For 16-outlet capacity at 120V, the PDU41021 adds outlet count at the same 1U form factor. For 0U vertical deployments, the PDU41116 provides a 16-outlet alternative. Review the full rack PDU category to match outlet count, current rating, and form factor to your specific rack build.
Frequently Asked Questions
Q: What input plug type does the PDU41004 use, and does it need an adapter for a standard UPS output?
A: The PDU41004 uses an IEC-320 C14 input plug, which connects directly to the IEC-320 C13 output receptacles found on most rack-mount UPS systems — no adapter required. The 10 ft (3.0 m) cord provides adequate reach for standard rack configurations.
Q: Can the PDU41004 be managed remotely without additional software?
A: Yes. The PDU41004 includes a built-in management interface accessible via HTTPS and supports SNMPv1/v3, SSH, Telnet, and HTTP out of the box. It also integrates with LDAP(S), RADIUS, and Windows Active Directory for enterprise credential management, and supports Syslog for centralized log aggregation.
Q: What is the maximum continuous load the PDU41004 supports?
A: The PDU41004 has a maximum input current of 15A but is derated to 12A for continuous operation. This 80% derating is standard practice for 24/7 equipment loads and protects against thermal stress. Plan total outlet load against the 12A continuous rating.
Q: Does the PDU41004 include overload protection?
A: No. The PDU41004 does not include built-in overload protection. The upstream circuit breaker or UPS must provide overcurrent protection. Factor this into your power design — do not rely on the PDU itself to protect against overload conditions.
Q: Can the PDU41004 be mounted on a wall instead of in a rack?
A: Yes. The PDU41004 ships with two sets of adjustable L-brackets (short and long) that support horizontal rack mount, vertical rackmount, and direct wall mount without purchasing separate hardware.
Q: What is the warranty on the PDU41004?
A: The PDU41004 carries a 3-year limited manufacturer warranty. An extended warranty (WEXT5YR-PDU1A) is available as an add-on for 5-year coverage.
The PDU41004 is one of the few 1U managed PDUs I recommend without qualification for mixed-voltage NVR head-end installs — specifically because the 100–240 VAC universal input eliminates the common mistake of ordering a 120V-only unit for a rack that ends up on a 208V circuit. I've seen that burn installs more than once. With 8 switched C13 outlets and a full SNMPv3/HTTPS management stack in a 1U form factor at this price tier, it covers the core requirements for a managed security equipment rack without the overhead of a dedicated power monitoring appliance.
Technical Highlights:
- 12A Derated Continuous Rating: The 80% derating from the 15A nameplate is pre-applied — not something you calculate separately. At 12A continuous across 8 C13 outlets, you have roughly 1.5A average headroom per outlet at 120V before the aggregate ceiling, or about 300W at 240V before hitting the limit. Plan your NVR, switch, and encoder loads accordingly.
- Full Enterprise Protocol Stack: SNMPv3, HTTPS, SSH, LDAP(S), RADIUS, and Windows AD are all listed — this is meaningful for corporate IT teams that need PDU management integrated into existing NOC tooling and directory policy, not just a web UI that lives outside your security perimeter.
- Optional Environmental Sensor via RJ45: The universal RJ45 port for an add-on environmental sensor is underused in most deployments. In a wiring closet or camera head-end room without dedicated HVAC monitoring, pairing the PDU41004 with a CyberPower-compatible temperature/humidity sensor turns a single SNMP poll into both power and environmental monitoring from one device.
Deployment Considerations:
- The C14 input plug requires a corresponding C13/C14 source — typically a UPS with C13 output receptacles or a facility C14 whip. If your rack UPS provides NEMA 5-15R or NEMA L5-20R outputs, you'll need a plug adapter or a different PDU input variant. Confirm source receptacle type before ordering.
- There is no built-in overload protection on the PDU41004. The upstream breaker — typically the UPS internal breaker or facility panel — is the only overcurrent protection in the chain. Do not assume the PDU will trip before an overload damages connected equipment.
This unit is well-suited for enterprise security head-end rooms and NVR rack builds where the facility may be running 208V two-phase from a PDU panel — the universal input handles it without a second SKU, and the SNMP stack integrates cleanly into a building management or NOC environment that's already polling UPS and switch infrastructure.
