CyberPower OL10KRTHD Double-Conversion Online UPS
Overview
The CyberPower OL10KRTHD is a 10kVA double-conversion online UPS built for surveillance operations, data centers, and network closets where continuous clean power is non-negotiable. This 4U rack-mount system delivers 10,000 watts of pure sine-wave output across configurable voltage rails (200–240 VAC), handles input fluctuations from 120–280 VAC without load shedding, and ships with a pre-installed RMCARD205 network management card — so remote monitoring and coordinated shutdown are ready from day one. Hot-swappable sealed lead-acid battery modules and support for up to 10 external battery expansions mean you can dial in runtime to match your facility's failover window, not the other way around.
Key Features
- Double-conversion topology: Inverts incoming AC to DC, then back to a precisely regulated sine wave. Unlike standby or line-interactive UPS designs, this eliminates switching transients that can corrupt video streams, crash NVRs, or trigger nuisance alerts on sensitive security systems. Every millisecond your recorders stay online counts.
- 10,000 VA / 10,000 W capacity: Handles a full rack of surveillance servers, PoE switches, and access control gear without derate. In real deployments, this means you're not guessing whether a 3-camera + NVR load fits — the math is straightforward.
- ECO mode with >98% efficiency: When utility power is stable, ECO mode bypasses the inverter and runs load directly, cutting heat generation and extending component life. That matters in cramped comms closets where UPS failure is usually a thermal death spiral.
- Pre-installed RMCARD205 management card: No separate purchase or slot-card fumbling. SNMP, USB, serial, and emergency power-off (EPO) are built in — plug into your network monitoring stack, set SNMP traps, and you'll know about a battery discharge or utility event before your NOC sees the power meter flicker.
- Hot-swappable 16 x 12V/9Ah sealed lead-acid battery modules: Maintenance-mode battery replacement without shutting down the UPS or your systems. Runtime is 2.4 minutes at full 10kW load and 8.3 minutes at half load. If that's not enough, daisy-chain up to 10 external battery modules (EBMs) to stretch runtime into the multi-hour range — critical for staged graceful shutdown or diesel generator spin-up in larger facilities.
- Configurable output voltage (200/208/220/230/240 VAC ±2%): Matches regional and legacy equipment standards without separate step-down transformers. If your NVR is rated 220V and your site standard is 240V, the OL10KRTHD delivers exactly what the equipment expects.
- Generator-compatible mode: Accepts noisy AC from a generator or portable source without failing — a real advantage in emergency scenarios where a standard UPS would fault on harmonic distortion.
- 4-hour recharge to 90% (0–90% charging window): If you've got a short outage and need rapid recovery to full capacity, the charging window is practical for shift-based operations. In a longer blackout, plan for the full recharge cycle.
- 6 standard NEMA L6 outlets plus hardwire terminal block: 4x L6-20R (20A) and 2x L6-30R (30A) outlets cover most rack-mounted security appliances. Hardwire terminal block eliminates plug-and-socket failure points for mission-critical feeds — no loose connectors to blame for an outage.
Integration & Compatibility
The OL10KRTHD integrates with industry-standard management platforms via SNMP, serial, and USB. PowerPanel Business Edition (included) offers centralized monitoring across multiple UPS units and sites. EPO (Emergency Power-Off) relay support means coordinated shutdown with security systems, fire panels, or access control integrations. The hardwire output is ideal for direct-feed redundancy to NVR power distribution panels, eliminating single-point-of-failure outlet dependencies.

Frequently Asked Questions
Q: What's the actual runtime if I only load 50% capacity?
A: The OL10KRTHD delivers 8.3 minutes at half load (5kW). Full load runtime is 2.4 minutes. For longer backup windows, add external battery modules — each EBM extends runtime proportionally, and the UPS supports up to 10 for multi-hour coverage.
Q: Can I add external batteries without powering down the NVR?
A: Yes. Hot-swappable batteries and modular external battery modules can be installed while the UPS is online and supplying load. The system transitions seamlessly.
Q: Does the OL10KRTHD work with my surveillance software's power-fail alerts?
A: Yes, via SNMP traps through the pre-installed RMCARD205. Configure SNMP in your VMS (Milestone, Axis Camera Station, etc.) to receive notifications of power events, battery low, or imminent shutdown.
Q: What happens if the generator output is dirty or unstable?
A: The OL10KRTHD's generator-compatible mode accepts input from 120–280 VAC, tolerating harmonic distortion that would fault a standard UPS. Double-conversion topology then cleans the output to your recorders.
Q: Is the 3-year warranty on the batteries or just the UPS unit?
A: The 3-year limited warranty covers the entire unit, including the sealed lead-acid batteries. The $300,000 Connected Equipment Guarantee protects downstream gear if a UPS malfunction causes damage.
Q: How much physical space does this take in a rack?
A: The OL10KRTHD is 4U height (6.8 inches deep), standard 19-inch rack width. Dimensions are 17.05 x 6.8 x 28.35 inches; weight is 157 lbs, so use a reinforced rack and mount with all supplied brackets.
I spec the OL10KRTHD into multi-site surveillance rollouts where NVR outages cost real money — lost incident footage, broken chains of custody, insurance gaps. The double-conversion topology on the OL10KRTHD is the detail that matters. It doesn't just supply power; it delivers a pure sine wave regardless of what's happening on the utility side. That separation between dirty input and clean output is why I reach for this unit instead of a line-interactive model when the NVR is mission-critical.
Technical Highlights:
- Double-conversion (VFI architecture): Every amp to the load goes through inverter conditioning — zero switching transients, zero harmonic pass-through. That cleanness keeps video encoding streams stable and prevents the cascade failures I've seen when cheap standby UPS units tried to feed a failing power supply.
- Hot-swappable 16 x 12V/9Ah sealed lead-acid modules: Means a battery change is a 10-minute job, not a facility shutdown. In a 24/7 surveillance environment, that's the difference between a planned maintenance window and an emergency service call at 2 AM.
- Pre-installed RMCARD205 with SNMP: No card-slot fumbling, no separate purchase. Plug the network port into your monitoring stack, and you get battery alerts, utility events, and EPO signaling from day one. I've seen sites miss outages for hours because they didn't budget for the network card — this eliminates that gap.
- 10,000 W capacity with generator-compatible input (120–280 VAC): Handles a full set of PoE switches, NVRs, and access control gearing without derate, and accepts noisy generator output without faulting. That flexibility is critical in facilities where you can't rely on utility stability or where backup power comes from a portable set.
- 4-hour recharge to 90%: In a brief outage scenario (utility trip + generator spin-up), you can recover to near-full capacity within a shift — practical for sites that don't need multi-hour battery endurance but do need fast recovery.
Deployment Considerations:
- Runtime at full 10kW is only 2.4 minutes — if your NVR shutdown procedure and graceful backup sequence take longer than that, plan for external battery modules (EBMs) from the start. Each module extends runtime; the UPS supports up to 10. Budget that into your initial quote.
- Hardwire terminal block has no overcurrent protection built into the UPS — that output is raw. If you're feeding a breaker panel or distribution block from the hardwire terminals, verify that your downstream panel has appropriate circuit protection. A shorted load on that hardwire feed will not trip the UPS; it will trip your site's main panel.
- Sealed lead-acid batteries degrade in high heat — operating range is 32–104°F. If your comms closet regularly hits 90°F+, factor in cooling or derating battery life from the stated 3-year window.
Position the OL10KRTHD into mid-to-large surveillance facilities, multi-building campuses, or any site where a single NVR failure cascades into liability. The upfront cost is real, but so is the cost of recovering footage from a crashed recorder. Double-conversion is the architecture that keeps that risk off the table.
