CyberPower 100-125 VAC 5-20P 2U Rack/Tower - OL2K2RTHDTAA

CyberPower OL2K2RTHDTAA Online UPS 2200VA Rack/Tower

The CyberPower OL2K2RTHDTAA is a 2200VA online double-conversion uninterruptible power supply built for surveillance, networking, and commercial security deployments where power continuity is non-negotiable. This 2U rack-mountable unit delivers 1800W of continuous output with zero-millisecond transfer time — meaning video recorders, network switches, and access-control systems stay powered through mains interruptions without dropout or relay chatter.

Overview

Online double-conversion topology converts incoming AC to DC, charges internal batteries, and converts back to clean AC output — eliminating exposure to mains noise, sags, and surges that degrade equipment life or trigger false resets on sensitive security controllers. The OL2K2RTHDTAA accepts input from 100–125 VAC (40–70 Hz) and delivers output regulated to ±2% — tight enough for modern IP camera and NVR power supplies that reject out-of-spec voltage. Eight outlets (seven NEMA 5-20R + one L5-20R locking connector) let you plug in cameras, NVRs, PoE switches, and access panels without external power distribution units.

Key Features

• Online Double-Conversion Topology: All power flows through battery circuitry, isolating equipment from mains transients, harmonics, and frequency instability — real insurance for 24/7 recorders in multi-site deployments where utility power is unreliable.
• 2200VA / 1800W Capacity: Enough headroom for a typical surveillance rack (2–3 IP cameras at 10–15W each, one 16-port PoE switch at 240W, plus one 4-channel NVR at 60W, leaving reserve for growth). Sizing calculator: add up your expected load and verify it stays below 1800W continuous.
• 0 ms Transfer Time: Instantaneous switchover to battery — no brief power dip that causes cameras to reboot or ethernet links to drop. This is why online UPS exists.
• Runtime Specifications: 6 minutes at full 1800W load (enough to ride out brief outages or trigger a graceful NVR shutdown); 16 minutes at half load (900W) — typical for a lightly-loaded security rack with one or two active recorders. Battery type is sealed lead-acid with 4-hour recharge time from mains.
• Voltage Regulation ±2%: Maintains rock-solid 120V output even when mains fluctuates — eliminates nuisance low-voltage alerts on power supplies and protects aging PSU capacitors from accelerated thermal stress.
• Eight Outlets (7x NEMA 5-20R, 1x NEMA L5-20R Locking): Standard US 20A receptacles cover cameras and PoE switches; locking L5-20R secures a single critical load (main NVR or backup power module) against accidental unplugging. Cord length is 10 feet, sufficient for rear-mounted infrastructure in most racks.
• Surge Suppression 710 J: Protects against phantom inrush on reconnection and nearby lightning transients — not a substitute for site-level surge protection, but adds a layer of defense for equipment plugged directly into the unit.
• SNMP & Serial Remote Monitoring: USB, serial, and optional SNMP card (RMCARD205) let you monitor load, battery health, and AC status from your management workstation. PowerPanel Business Edition software included for Windows integration and scheduled graceful shutdown if runtime expires.
• Harmonic Distortion <5%: Clean sine-wave output (not stepped approximation) means no interference with sensitive analog signals or RF interference on access-control card readers. Network switches and PoE hardware see textbook 120V 60 Hz.
• Automatic & Manual Bypass: If internal circuitry fails (rare), automatic bypass routes power directly to outlets from mains — equipment stays on. Manual bypass switch lets you service the UPS without shutting down the rack.
• Thermal Efficiency: ECO mode dissipates 176 BTU/hr (43W equivalent); full online mode dissipates 497 BTU/hr (146W) — factors in if your server room or cabinet has tight cooling. Audible noise ranges 24.2 dBA (quiet ECO mode) to 57.1 dBA (active cooling under heavy load) — acceptable in a wiring closet, noticeable in an office.

Integration & Compatibility

The OL2K2RTHDTAA integrates with any equipment that accepts standard 120V 60 Hz input. Surveillance integrators typically pair this with network video recorders, managed PoE switches, and access-control panels. USB and serial ports connect to a management PC running PowerPanel Business Edition — a standard tool across CyberPower's commercial line. SNMP support (via optional RMCARD205) allows integration into SNMP-based monitoring stacks (Nagios, Zabbix, PRTG) for remote alerts if battery capacity drops or runtime is exhausted. The UPS is UL1778 and CSA C22.2 No.107.3 certified, meeting US and Canadian safety standards; FCC Part 15 Class A means it operates in commercial/industrial environments without exceeding conducted or radiated emissions limits.

Operating & Environmental Specifications

The unit operates from 0–40°C ambient (typical for climate-controlled server rooms and wiring closets) and stores safely from −15 to 45°C. Operating elevation to 3,000 m (9,843 ft) — suitable for most populated areas; storage tolerance extends to 14,999 m. Humidity range is 0–90% operating (non-condensing) and 0–95% storage, accommodating coastal or high-humidity installations provided condensation is avoided. Weight is 17.5 kg (38.6 lbs), so two people can safely lift into a 2U rack space; shipping weight 21.3 kg accounts for packaging.

Frequently Asked Questions

Q: How long does the OL2K2RTHDTAA run a typical surveillance NVR?

A: At half load (approximately 900W), the unit delivers 16 minutes of runtime — enough for most 4–8 channel NVRs to shut down gracefully or for brief utility hiccups to pass. Full load (1800W) yields 6 minutes. Actual runtime depends on battery age and ambient temperature.

Q: Can I upgrade the battery?

A: The OL2K2RTHDTAA uses four sealed lead-acid batteries inside. Replacements are available from the manufacturer or authorized battery suppliers; swapping takes approximately 30 minutes and requires a screwdriver and minimal electrical knowledge.

Q: Does the OL2K2RTHDTAA output true sine wave?

A: Yes. The unit produces a pure sine-wave output (not stepped or modulated), with harmonic distortion below 5%. This ensures compatibility with sensitive equipment like IP cameras, analog interfacing modules, and RF-sensitive access readers.

Q: What's the difference between online and standby UPS?

A: Online (double-conversion) UPS like the OL2K2RTHDTAA continuously conditions power through the battery circuit, providing 0 ms switchover and isolation from mains noise. Standby models wait for a voltage event to kick in, causing a brief blip. For surveillance deployments with networked cameras, online is the safer choice.

Q: Is SNMP monitoring included or optional?

A: SNMP capability requires the optional RMCARD205 remote management card. USB and serial monitoring via PowerPanel Business Edition software are included.

Q: Can the OL2K2RTHDTAA be wall-mounted or does it require a rack?

A: The unit supports both 2U rackmount installation and standalone tower operation (mounting feet on the base). Choose the form factor that fits your infrastructure.

Jerry Tildsen

The OL2K2RTHDTAA is built for surveillance integrators who've learned that cheap standby UPS units create more headaches than they prevent — camera reboots, corrupted NVR filesystem entries, lost motion events during power sags. Online double-conversion solves this by eliminating the transfer-time gap that trips up networked gear. I specify this model when a customer has unreliable utility power or when the deployment includes more than four IP cameras and a managed switch; the zero-millisecond switchover and ±2% voltage regulation keep your recorder and ethernet stack alive through mains transients that would otherwise trigger cascading resets.

Technical Highlights:

• Online Double-Conversion with 0 ms Switchover: All power flows through the battery circuit continuously, isolating your surveillance gear from mains noise, sags, and spikes. Networked cameras stay connected; NVRs don't lose filesystem integrity.
• 1800W @ ±2% Voltage Regulation: Maintains tight 120V output across load swings — modern PoE switches and camera PSUs appreciate this stability, and you avoid nuisance low-voltage shutdown messages on aging hardware.
• 6-Minute Full Load / 16-Minute Half Load Runtime: Enough time to execute a graceful NVR shutdown or ride out typical brownout events. At 900W (half load), you get 16 minutes — realistic for a lightly-loaded security rack with one active recorder and PoE switch in standby.
• Eight Outlets with One Locking L5-20R: Seven standard NEMA 5-20R plus one hardwired locking connector. Locking connector prevents accidental unplugging of your primary NVR — a real field problem if physical access is loose.

Deployment Considerations:

• Runtime at full load (1800W) is only 6 minutes — not enough for a site power-down unless your NVR can shut down in under 5 minutes. Size your load conservatively and test the actual shutdown procedure before relying on graceful-exit workflows.
• Sealed lead-acid batteries degrade predictably; schedule replacement every 3–5 years if the UPS cycles frequently. If utility power is stable and outages are rare, battery life extends. Monitor battery health via PowerPanel software — it will alert you when voltage sag indicates aging cells.
• The unit dissipates 146W (497 BTU/hr) in full online mode — factor this into your wiring closet HVAC if it's undersized or in a warm climate.

I deploy the OL2K2RTHDTAA in retail surveillance racks, industrial facility access-control rooms, and multi-site deployments with temperamental utility power. It's the right choice when you need zero-tolerance power conditioning and your load stays under 1800W.
