Vertiv 38059 1U Rackmount Surge-Protected PDU
Overview
The Vertiv SP104-1025TL (part number 38059) is a 1U horizontal rackmount power distribution unit built for IT racks and security equipment enclosures that need reliable 20A power delivery with built-in surge protection — especially in facilities that lack surge suppression at the panel level. It delivers 120V/20A (1.9kW) across ten NEMA 5-20R receptacles, connects via a NEMA L5-20P twistlock plug to your 20A dedicated circuit, and mounts flush in any standard 19-inch rack. If you're powering a row of IP cameras, NVRs, network switches, or a mixed surveillance rack without upstream surge suppression, this is the PDU to reach for.
Part of the Vertiv PowerIT rPDU line, the SP104-1025TL is factory-tested 100% before shipment and carries a five-year limited warranty — longer than most competitive units in this class. TAA compliance and Buy American Act COTS status make it a straightforward procurement for government projects and federal integrators.
Key Features
- Ten NEMA 5-20R Rear Outlets: All ten receptacles are rated to the full 20A circuit capacity. In practice, you'll stay under 16A continuous load (80% derate rule), but having all ten on a single 20A breaker means you can power a full rack of PoE switches, NVRs, and access control panels without splitting across multiple circuits. Duplex-style outlets are grouped 5+5 on the rear panel.
- 720-Joule Surge Rating with 340V Clamping Voltage: The Super MOVS technology clamps surge events before they reach connected equipment. At 720J this isn't a premium whole-facility suppressor — it's a last line of defense for the rack. Pair it with facility-level suppression for mission-critical surveillance servers, but for a standard security rack it handles the transient spikes that degrade NVR power supplies and camera injectors over time.
- 20A Thermal Breaker with Switch: The thermal breaker trips under sustained overload without needing a fuse replacement — just reset the breaker once load is corrected. The included switch means you can cut power to the entire rack strip without pulling the L5-20P twistlock from a tight panel. Useful during maintenance windows on live racks.
- L5-20P Twistlock Plug, 10ft Cord, 12/3 Wire Gauge: The NEMA L5-20P twistlock plug locks to the receptacle and won't pull free accidentally — critical in rack environments where cable management is tight and physical disturbance happens. The 10-foot 12/3-gauge cord handles the full 20A load without voltage drop at typical rack-to-panel distances. Make sure your PDU panel circuit is a 20A dedicated NEMA L5-20R receptacle before ordering.
- 1U Flush-Mount Horizontal Form Factor (1.72in H × 17in W × 3.75in D): At 1.72 inches tall, this occupies exactly 1U of rack space. The 17-inch chassis width fits standard 19-inch racks with standard mounting rails. Flush-mount capability means the unit sits flat against the rear of the rack — no protruding bracket required. Shipped weight is 7lbs, so one person can install it.
- Surge Indicator Red LED + Power-On Green LED: Two discrete LEDs give you at-a-glance status without pulling monitoring software. The red LED fires when the surge protection module has experienced significant events and may need attention. The green power-on LED confirms the unit is live. Simple, but exactly what you need in a densely cabled rack where you can't trace every power cable.
- TAA Compliant + Buy American Act COTS + RoHS + UL/c-UL Listed: TAA compliance (country of origin: USA) means this PDU qualifies for federal, state, and many municipal contracts without a waiver. UL and c-UL listing under 60950 satisfies most AHJ requirements. RoHS compliance handles EU-bound deployments. This combination means you can spec it into virtually any commercial or government project without certification questions.
- Connected Equipment Warranty — 5 Years / $5,000: Vertiv backs connected equipment up to $5,000 over five years if the surge protection fails to prevent damage. This isn't just a warranty claim — it's evidence that Vertiv has confidence in the MOVS design. For an NVR running $2,000–3,000 of connected recording hardware, that coverage matters when writing a maintenance agreement.
- 100–120V, 50/60Hz Input: Covers standard North American 120V circuits at both 60Hz (US) and 50Hz (where applicable). Not a dual-voltage unit — this is not for 208V or 240V circuits. Verify panel voltage before installation.
Integration and Compatibility
The SP104-1025TL is a passive rackmount PDU — no network management port, no per-outlet switching, no remote monitoring. It pairs cleanly into any rack or cabinet alongside network video recorders, PoE switches, access control panels, and other fixed-load equipment. For environments requiring per-outlet power monitoring or remote reboot capability, step up to Vertiv's metered or switched rPDU families. For this unit, management is physical: breaker, switch, and two LEDs. That simplicity is an advantage in hardened security closets where network-managed PDUs introduce an additional IP device to secure and patch.
The L5-20P twistlock input is a deliberate design choice — it requires a matching NEMA L5-20R panel receptacle. Most dedicated 20A circuits in data centers and security rooms are wired this way, but verify before spec'ing. Standard NEMA 5-20P straight-blade circuits are not compatible with this plug. If your panel has NEMA 5-20R straight receptacles, this PDU does not fit without an adapter (which Vertiv does not recommend for permanent installations). Plan the panel circuit during power planning for the rack.
At 10°C–45°C (50°F–113°F) operating range, the SP104-1025TL suits conditioned data rooms and security head-end rooms. It is not rated for outdoor enclosures or unconditioned spaces above 45°C. For outdoor equipment cabinets or hot aisles running above that threshold, verify thermal conditions before specifying.
Frequently Asked Questions
Q: Is the Vertiv 38059 TAA compliant?
A: Yes. The SP104-1025TL is manufactured in the USA, TAA compliant, and Buy American Act COTS compliant, making it eligible for federal, state, and many municipal procurement contracts.
Q: What plug type does the 38059 require at the panel?
A: The unit uses a NEMA L5-20P twistlock plug, which requires a dedicated NEMA L5-20R 20A circuit at the panel. Standard NEMA 5-20P straight-blade circuits are not compatible — confirm your panel receptacle type before ordering.
Q: What is the warranty on the 38059?
A: Vertiv provides a 5-year limited product warranty. Additionally, the connected equipment warranty covers up to $5,000 over 5 years if surge protection fails to prevent damage to connected devices.
Q: Does the 38059 have network management or per-outlet control?
A: No. The SP104-1025TL is a basic (non-managed) PDU. It has a master switch and two status LEDs (green power-on, red surge indicator) but no IP management port, per-outlet switching, or remote monitoring capability. For managed power distribution, consider Vertiv's metered or switched rPDU families.
Q: How many outlets does the 38059 provide and what receptacle type?
A: Ten NEMA 5-20R duplex-style receptacles, all located on the rear panel. Each is rated at 20A/120V, with all ten sharing the single 20A thermal breaker. Per the 80% continuous load rule, plan for a maximum of 16A sustained draw across all outlets.
Q: What is the joule rating and clamping voltage of the surge protection?
A: The SP104-1025TL provides 720 joules of surge energy absorption with a maximum clamping voltage of 340V, using Super MOVS technology. This is appropriate for rack-level transient suppression in facilities that also have upstream panel-level protection.
The spec I keep coming back to on the 38059 is the L5-20P twistlock input — it tells you exactly who this PDU is designed for. Twistlock plugs are standard in properly-built security head-ends and data rooms where a bump to the power cord can't be allowed to drop an NVR mid-recording. If you're speccing this into a rack where the panel has straight-blade NEMA 5-20R circuits, stop and sort out the panel first — this is not a plug-and-play situation without matching infrastructure.
Technical Highlights:
- 720J / 340V Clamping: Adequate for rack-level transient protection on a circuit that already has panel-level suppression. Not a standalone whole-facility solution — the 720J rating will absorb typical switching transients and small surge events, but if your facility has no upstream suppression, budget for a parallel suppressor at the panel before relying on this alone.
- 10x NEMA 5-20R on a single 20A breaker: All ten outlets share the one 20A thermal breaker, which means a sustained overload on any combination of outlets trips the whole strip. Size your load to 16A continuous maximum across all ten positions — that's 1.92kW at 120V, enough for a typical 4–8 camera NVR rack with a managed switch and access control panel, but tight if you're adding high-draw servers.
- 5-Year / $5,000 Connected Equipment Warranty: Vertiv backs this with real connected-equipment coverage — $5,000 over five years. On a rack with a $2,500 NVR and several hundred dollars of PoE switches, that coverage is a meaningful part of the value argument when writing a maintenance agreement for a client.
Deployment Considerations:
- The 1U flush-mount form factor (1.72in × 17in × 3.75in) works cleanly in standard 19-inch racks at 7lbs shipped weight. Mount it at the bottom of the rack to keep the 10-foot cord run manageable — running a 10ft cord from a mid-rack mount to a floor-level panel receptacle rarely works cleanly without cable management accessories.
- Operating temperature ceiling is 45°C (113°F) — that's within spec for a conditioned equipment room, but watch hot-aisle temperatures in densely packed racks. If your rack runs consistently above 40°C measured at the PDU, you're in marginal territory.
This PDU is the right call for a government-contract surveillance head-end room or a security integrator installing a 6–10 camera NVR rack in a facility with a properly wired 20A dedicated circuit and L5-20R panel receptacle. TAA compliance closes procurement without additional paperwork, and the five-year warranty matches typical maintenance contract cycles for commercial security installations.
