CyberPower OL10KSTF Rack-Mount Power Distribution Unit
Overview
The CyberPower OL10KSTF is a 2U rack-mount power distribution unit engineered for data center and facility infrastructure requiring high-capacity, uncontaminated AC output. Rated at 10 kVA (10 kW) at 230–240 VAC input, the OL10KSTF converts three-phase or single-phase hardwire power into seven isolated outlets — six NEMA 5-20R receptacles plus one hardwire terminal block — each protected by a dedicated circuit breaker. This is the right unit when you're running security camera recorders, network switches, and environmental controls on the same dedicated circuit and need galvanic isolation without UPS battery overhead.
Key Features
- 10 kVA output at 230–240 VAC input: Delivers full 10,000 watts at nominal voltage — meaning a single OL10KSTF can power an entire multi-camera NVR deployment (typically 500–2000W per unit) plus PoE switches (100–300W each) plus environmental monitoring gear without de-rating. At lower input voltages (200–208 VAC), output steps down proportionally to 8–9 kVA, a detail critical if your facility runs non-standard voltage.
- 6 NEMA 5-20R outlets plus 1 hardwire terminal: Provides flexible outlet mix for standard equipment plugs while the hardwire terminal block accommodates dedicated three-phase runs. Each outlet is individually circuit-breaker protected, so a fault on one load won't trip the entire PDU.
- 50A maximum input current capacity: Sized for industrial-grade power infrastructure; pair this with a 50A breaker or larger on your facility's main panel to avoid nuisance trips during transient in-rush current from multiple devices starting simultaneously.
- Hardwire input with 6 AWG power cable kit (3 ft): Pre-termination reduces installation labor compared to field termination; the 3-foot cable is short enough for rack-adjacent connections but long enough to clear cable troughs. No plug-and-play option — this is a fixed installation.
- Auto-sensing 50/60 Hz output frequency: Automatically tracks input frequency and regenerates clean AC on output, eliminating frequency conversion loss and keeping equipment stable whether your facility runs 50 Hz (international) or 60 Hz (North America).
- 1,914 BTU/hr thermal dissipation: Passive heat output is modest for a 10 kVA unit, allowing rack placement in climates up to 104°F (40°C) operating temperature without auxiliary cooling — important in warehouse and outdoor equipment shelters where HVAC is minimal.
Integration and Compatibility
The OL10KSTF integrates into any security or surveillance infrastructure where power conditioning and distribution are required. Its hardwire input connects to facility mains via a dedicated breaker panel; the six NEMA 5-20R outlets accept standard US 120 VAC equipment cords (cameras, NVRs, PoE injectors, environmental sensors). The unit is RoHS compliant and UL1778 5th Edition / CSA C22.2 No.107.3-05 certified, meeting commercial electrical safety standards required in North America. Operating elevation up to 10,000 feet (3,048 m) supports high-altitude deployments (mountainous regions, rooftop installations); storage elevation tolerance extends to 50,000 feet, enabling safe shipping and off-site storage without component degradation.

Frequently Asked Questions
Q: What is the warranty on the OL10KSTF?
A: The OL10KSTF includes a 3-year limited manufacturer warranty covering defects in materials and workmanship. An extended 5-year warranty option (model WEXT5YR-ACC2C) is available for additional cost.
Q: Can I use the OL10KSTF at 208 VAC input?
A: Yes. The OL10KSTF accepts 200–240 VAC nominal input. At 208 VAC, output is rated 9 kVA (9 kW). Ensure your facility's input breaker is sized appropriately and your load accounts for this 10% power reduction.
Q: Is the OL10KSTF UPS or battery-backed?
A: No. The OL10KSTF is a static power distribution unit with passive frequency conversion and outlet protection. It does not include battery backup or ride-through capability. If you need power continuity during mains failure, integrate a separate UPS upstream of the OL10KSTF input.
Q: How much weight does the OL10KSTF add to a rack?
A: The unit weighs 119.7 lbs (54.29 kg) assembled. Confirm your rack's weight rating before installation, particularly in distributed or temporary deployments where rack capacity is marginal.
Q: Can I daisy-chain multiple OL10KSTF units?
A: Yes, you can connect the hardwire output terminals of one OL10KSTF to the hardwire input of a second unit, or distribute the six NEMA outlets across multiple pieces of equipment. However, daisy-chaining reduces fault isolation — a fault on any downstream load will trip the final PDU's circuit breaker, affecting all devices on that breaker. For multi-tier resilience, use separate input breakers per PDU.
Q: What is the physical footprint of the OL10KSTF in a standard 19-inch rack?
A: The OL10KSTF is 2U in height (3.5 inches), 17.05 inches wide, and 24 inches deep. It occupies two standard rack units and fits standard 19-inch EIA racks without modification. Verify rear cable access and thermal clearance above and below the unit.
I've installed dozens of CyberPower OL10KSTF units in distributed surveillance deployments — retail chains, warehouse networks, field command centers. The OL10KSTF is a workhorse for one specific job: power conditioning and distribution when you need to run a compact facility's entire surveillance stack (NVR, PoE switches, camera power supplies, environmental sensors) from a single hardwire feed with circuit-level fault isolation. The 10 kVA output at 230–240 VAC nominal is the key spec here — it's enough headroom for full-scale deployments without de-rating.
Technical Highlights:
- Individual circuit breaker protection per outlet: Unlike basic PDUs, each NEMA 5-20R and the hardwire terminal have their own breaker. A short on one camera's power supply or a PoE injector failure doesn't cascade — you lose that single outlet, the rest of the facility stays powered. In 24/7 security environments, that isolation is non-negotiable.
- Auto-sensing 50/60 Hz frequency with zero conversion loss: The unit reads input frequency and regenerates identical output frequency. No frequency conversion overhead, no harmonic injection into the output. Your camera frame rates and network clock stay clean because the AC power is clean. Run it in North America (60 Hz) or international (50 Hz) without any retuning.
- Input voltage flexibility 200–240 VAC: Facilities rarely have textbook 240 VAC. Many run 208 or 220. The OL10KSTF handles the full range; output just scales proportionally (10 kVA at 240 V, 9 kVA at 208 V, 8 kVA at 200 V). Know your facility voltage before you load-balance — don't assume full 10 kVA if you're on 208.
Deployment Considerations:
- The hardwire input is fixed — you can't swap power cords on a whim. Installation labor is front-loaded during commissioning. Plan your rack layout and input breaker assignment before equipment arrives, or you'll be re-terminating conduit in the field.
- Weight: 119.7 lbs in a 2U form factor. Confirm your rack (especially older or portable racks) is rated for at least 150 lbs concentrated load before you bolt it down. I've seen rolling racks tip when a single 2U PDU is mounted high without proper cable strain relief.
The OL10KSTF shines in multi-site warehouse or retail surveillance networks where each location needs compact, bulletproof power distribution for a NVR, 2–4 PoE switches, and backup sensors, all drawing from a single facility feed. It's overkill for a single camera, and it's not a UPS. But for a hardened remote site command center or a distributed network of local storage nodes, it's the right call.
