CyberPower 100-125 VAC L5-30P 2U Rack/Tower - OL3KRTHDTAA

CyberPower OL3KRTHDTAA Online Double-Conversion UPS

The OL3KRTHDTAA is a 3000VA industrial-grade online UPS rated for surveillance, security, and mission-critical network environments where clean, uninterruptible power is non-negotiable. Built as a 2U rackmount with optional tower feet, it delivers 2700W continuous output via online double-conversion topology—the architecture that ensures zero-millisecond transfer time to battery on utility loss, meaning no brief power hiccup reaches downstream equipment. That matters: surveillance NVRs, access control panels, and switching fabric cannot tolerate even millisecond-scale interruptions without losing sync or dropping frames.

Key Features

• Online Double-Conversion Topology: Input power is converted to DC, then back to AC—eliminating relay switching delay. Zero-millisecond transfer time to battery means no dropout window; critical devices stay alive during utility sags, surges, or failures.
• 3000VA / 2700W Capacity with 0.9 Power Factor: Actual usable watts are 2700W (0.9 PF), not the inflated 3000VA that undersized units claim. That full 2700W means you can power a 24-port PoE switch (typical 250W), an NVR stack (400–600W), access control panel (100W), and still have headroom for expansion without overload risk.
• Runtime Flexibility Across Load Profiles: At full 2700W load, battery sustains 2.7 minutes—enough to gracefully shut down or failover. At half load (1350W), runtime extends to 8.5 minutes, giving time for automatic failover to backup power or UPS-triggered shutdown procedures. Real-world surveillance rigs typically run 40–60% of rated capacity, putting you solidly in the 8.5-minute envelope.
• High-Density 2U Form Factor: Fits standard 19-inch server racks without sacrificing outlets. Four 12V/9Ah batteries (48V nominal pack) deliver the runtime figures above. Recharge cycle is 4 hours to 90% capacity, supporting daily runtime testing or post-outage recovery on a normal office power schedule.
• Output Voltage User-Configurable (100/110/115/120/125 VAC): Accommodates regional power standards and legacy equipment requiring non-standard voltages. ±2% regulation maintains equipment compatibility even during battery operation. Combined with <3% harmonic distortion at linear load, sensitive network gear (phones, intercoms, encoders) stays protected from waveform noise.
• Seven Outlets (6× NEMA 5-20R + 1× NEMA L5-30R): The L5-30R output can be switchable, letting you isolate low-priority circuits during extended outages. Six standard 20A receptacles handle typical surveillance and network loads; the hardwired L5-30R provides a dedicated circuit for a secondary UPS, PDU, or external battery module if scaling beyond 8.5 minutes becomes necessary.
• Surge Suppression 710J: Protects against transient spikes that age capacitors and degrade MTBF. Useful in facilities with older electrical infrastructure or lightning-prone regions where utility sags and surges are routine.
• PowerPanel® Business Edition Management: Included software provides real-time UPS monitoring, battery health tracking, and scheduled shutdown logic. USB and serial ports enable local notifications; SNMP and EPO (Emergency Power Off) ports allow integration with building management systems and security consoles. Optional RMCARD205 remote management card adds web-based monitoring and remote reboot capability—essential for unattended data centers or remote surveillance hubs.
• ECO Mode >96% Efficiency: In ECO mode, the UPS acts as a high-quality power conditioner with line-interactive topology, reducing heat output and extending battery service life. Switches to full double-conversion automatically during utility disturbances.
• 3-Year Manufacturer Warranty and TAA Compliance: Built and sourced to meet Trade Agreements Act (TAA) restrictions, required for federal, state, and government contracts. Warranty covers parts and labor for 36 months.

Network and System Integration

The OL3KRTHDTAA integrates seamlessly with surveillance architectures. USB and serial connectivity trigger alerts within PowerPanel Business Edition; SNMP integration feeds battery status into Nagios, Zabbix, or custom monitoring dashboards. EPO (Emergency Power Off) command can be hardwired from a security console, allowing emergency shutdown of all UPS outlets if a facility-wide lockdown is required. This flexibility makes it suitable for secure server rooms, police evidence vaults, and data centers where power and access control must coordinate.

Environmental and Operational Considerations

The OL3KRTHDTAA accepts 100–125 VAC input across 40–70 Hz frequency range, tolerating utility fluctuations common in aging electrical infrastructure. Input plug is NEMA L5-30P (30A hardwired), requiring dedicated 30A circuit breaker protection. 10-foot (3.0m) power cord allows flexible placement within server room layouts. The 2U form factor and optional tower feet support both vertical rack mounting and horizontal placement on equipment shelves.

When to Choose a Different Model

If runtime longer than 8.5 minutes at half load is critical for your backup window, consider a larger-capacity UPS in the CyberPower family (6kVA or above) or an external battery expansion module paired with the OL3KRTHDTAA. If you need true three-phase power protection for a large facility, CyberPower's 3-phase online UPS line offers superior redundancy and load balancing.

Frequently Asked Questions

Q: Is the OL3KRTHDTAA compliant with federal procurement rules (TAA)?

A: Yes. The OL3KRTHDTAA is explicitly TAA-compliant, meeting Trade Agreements Act restrictions on country of manufacture and source components. Eligible for GSA, federal, and government contracts.

Q: What's the warranty on the OL3KRTHDTAA?

A: 3-year manufacturer warranty covering parts and labor.

Q: Does the OL3KRTHDTAA work in a rackmount configuration, or do I need tower feet?

A: The unit is designed as 2U rackmount and mounts directly into standard 19-inch server racks. Optional tower feet are available if you prefer horizontal placement on a shelf or bench.

Q: Can I monitor the OL3KRTHDTAA remotely?

A: Yes, via USB and serial locally, or by adding the optional RMCARD205 remote management card for web-based monitoring and remote reboot capability from anywhere on your network.

Q: What's the recharge time for the batteries after a power failure?

A: The battery pack (four 12V/9Ah cells) recharges to 90% capacity in 4 hours under normal utility power. Full 100% charge takes longer, but 4 hours covers most operational recovery windows.

Q: Will the OL3KRTHDTAA fit a 24-port PoE switch and an NVR simultaneously?

A: Yes. A typical 24-port managed PoE switch draws 250–350W; a surveillance NVR (8–16 bay) draws 400–600W. Combined 650–950W is well within the 2700W continuous output, leaving headroom for access control, intercoms, or modems.

Ted Perry

I specify the OL3KRTHDTAA when a surveillance facility cannot tolerate any power transition window. The zero-millisecond transfer time on the OL3KRTHDTAA is the key spec here—the moment utility power sags or fails, the inverter output stays synchronized without a single microsecond of dropout. For NVRs, IP phones, and access control panels, that seamless handoff prevents dropped frames, lost SIP registrations, and door controller resets. Most facilities don't realize that even 4-millisecond transition windows on cheaper line-interactive UPS units can trigger unexpected reboots or data corruption in surveillance software.

Technical Highlights:

• Online Double-Conversion with 0ms Transfer Time: Input rectifier and output inverter run continuously; no relay switching delay. Downstream surveillance equipment never sees a power interruption, keeping NVR recording and access control uninterrupted during utility sags or switchover events.
• 2700W Continuous Output (3000VA at 0.9 PF): The 0.9 power factor is honest—2700W actual usable watts, not marketing inflation. A typical 24-port PoE switch (300W) plus a 16-bay NVR (550W) leaves 1850W for redundant modems, intercoms, and future expansion.
• 8.5 Minutes Runtime at Half Load: Most surveillance installations run 40–60% capacity; the half-load spec is realistic for a graceful shutdown or failover sequence. At full 2700W, you get 2.7 minutes—enough to trigger emergency procedures and activate failover logic.
• Four 12V/9Ah Batteries with 4-Hour Recharge: Four-battery design provides good availability for daily testing without excessive charge cycles. 4-hour recharge window aligns with typical daily power cycles, meaning the unit is ready for tomorrow's outage by morning.

Deployment Considerations:

• The NEMA L5-30P input plug requires a hardwired 30A dedicated circuit—you cannot plug this into a standard outlet. Coordinate with your facility electrician before installation to ensure proper breaker protection.
• At full 2700W load, the 2.7-minute runtime is tight for unattended facilities; plan for either external battery expansion or UPS-triggered automatic failover to a secondary power source (generator, secondary utility circuit, or cloud failover for VMS).

Situate the OL3KRTHDTAA in secure facilities (government, banking, police) where TAA compliance is contractual and zero-transition power is operationally critical—the price premium and feature set justify themselves in those environments.
