CyberPower OL1KRTHD 1000VA Online UPS

Overview

The CyberPower OL1KRTHD is a 1000VA / 1000W double-conversion online UPS built for continuous power protection in surveillance control rooms, network closets, and security infrastructure. This 2U rackmount unit delivers 12 minutes of runtime at half load and 3.8 minutes at full load — enough margin to gracefully shut down systems or ride through brief utility sags without losing uptime on critical cameras, NVRs, and access control hardware. Double-conversion topology means the OL1KRTHD conditions every watt through battery power before delivery, eliminating transfer time (0 ms) and filtering input noise that would otherwise degrade sensitive electronics.

Key Features

• Double-Conversion topology with pure sine-wave output: Every connected device sees a clean, stable 120V sine wave regardless of input quality — essential for keeping surveillance encoders, network switches, and recording appliances free from glitches that noisy utility power can introduce. The 1:1 output power factor means you're not wasting capacity on reactive load.
• 8 NEMA 5-15R outlets, switched in pairs: Granular outlet control lets you prioritize critical loads (cameras, NVR, core network) and shed secondary devices when battery time is short. Paired switching prevents accidental overload from daisy-chained power strips.
• 0 ms transfer time: Online topology eliminates the typical 4–10ms switching delay that offline UPS models introduce. For video encoders and network devices sensitive to power interruption, zero-delay transfer keeps streams continuous and avoids dropped frames or session resets.
• 12-minute half-load runtime: If your surveillance system draws 500W (typical for a compact NVR + switch + modem + access control panel), you'll sustain it for 12 minutes on battery. That window is long enough to notify operations, cut non-critical services, and cleanly power down — or ride through a rolling brownout without data loss.
• 710J surge suppression: Protects against lightning-induced transients and utility spikes that commonly fail PoE switches and network interface cards. This is standard protection, but measure it against your site's lightning risk — higher-stress environments may benefit from external surge panels.
• Two 12V/9Ah sealed lead-acid batteries, 4-hour recharge to 90%: Standard industrial battery pair rated for 3–5 year lifespan in normal service. If you're running 24/7 surveillance with frequent power events, plan replacement cycles in your maintenance budget.
• SNMP, USB, and serial communication with PowerPanel® Business Edition: Real-time monitoring of load, battery health, and remaining runtime. SNMP traps alert your NOC to low-battery conditions. Optional RMCARD205 card adds remote reboot capability and environmental sensor integration.
• ECO mode efficiency >96%: In normal line-powered conditions, the unit switches to passive bypass mode, reducing heat and extending battery calendar life. When utility voltage drifts outside ±2%, automatic transfer to battery power engages.
• Input frequency range 40–70 Hz: Tolerates power systems with unusual frequencies (common in some industrial or remote sites). Most standard North American grids run 60 Hz, but this spec ensures compatibility if your facility has legacy or distributed power generation.
• Internal automatic and manual bypass: If the UPS itself fails, a mechanical bypass switch can reconnect load directly to utility power without service interruption. Essential fail-safe for high-availability surveillance that cannot tolerate a total power cutoff.
• 3-year limited manufacturer warranty: Covers defects in materials and workmanship. Battery is typically covered for the first year; plan a replacement set by year 2–3 if you're in a high-cycle environment.
• Audible alarms for battery mode, low battery, overload, and UPS fault: Immediate acoustic notification that power has shifted to battery — your security team hears the alert and can respond before runtime expires. Prevents silent failures.

Integration & Compatibility

The OL1KRTHD fits standard 19-inch racks in a compact 2U footprint. The 10-foot cord (NEMA 5-15P plug) reaches most wall outlets or PDU connections without extension cords — avoid chaining multiple UPS units or using daisy-stacked power strips, which invite cascading failures. USB and serial ports connect to a Linux or Windows management PC running PowerPanel® Business Edition; SNMP cards and protocols allow integration into Nagios, Zabbix, or proprietary monitoring dashboards common in security operations centers. If your NVR or access control system includes scheduled shutdown scripts, configure them to trigger on UPS low-battery traps — this ensures orderly shutdown rather than sudden power loss.

What's in the Box

Frequently Asked Questions

Q: What happens if the UPS itself fails while powering surveillance equipment?

A: The internal automatic bypass transfers load directly to utility power with no interruption. A manual bypass switch is also available on the rear panel for technician-assisted failover.

Q: Can I expand runtime by adding external battery packs?

A: The OL1KRTHD is not designed for external battery expansion. If you need longer runtime, evaluate a higher-capacity model (2000VA or 3000VA variants) or add a second smaller UPS for non-critical loads.

Q: Does the OL1KRTHD integrate with Milestone XProtect or Axis Camera Station?

A: Not directly through plugin. However, PowerPanel® Business Edition sends SNMP traps that your VMS can consume via standard monitoring agents, alerting operators to power events. Scripting your VMS to pause non-critical functions on low-battery triggers is also feasible.

Q: What is the typical battery replacement cost and lifespan?

A: The OL1KRTHD uses two standard 12V/9Ah sealed lead-acid cells. Expect 3–5 year lifespan in normal service; replacement sets cost $150–$250 depending on vendor. Keep spare batteries on hand if your site runs continuous surveillance with frequent power interruptions.

Q: Is the OL1KRTHD suitable for a remote site with unreliable utility power?

A: The OL1KRTHD is a UPS, not a generator. It bridges brief interruptions (seconds to minutes). For sustained outages, pair it with a fuel-backed generator or solar system. The UPS + generator combo is industry standard for remote surveillance.

Q: Can I monitor the OL1KRTHD remotely via the optional RMCARD205?

A: Yes. The RMCARD205 (sold separately) adds Ethernet-based remote management, allowing you to monitor load, battery health, and remaining runtime from a central NOC. It also provides remote power cycling (reboot) capability.

I've seen too many surveillance systems go dark because somebody thought a $50 surge protector was sufficient power protection. The OL1KRTHD OL1KRTHD addresses that directly: it's a proper online UPS with zero-millisecond transfer time and genuine 1000W capacity. For a typical control room running an NVR, PoE switch, modem, and access control panel, this unit buys you 12 minutes of clean power on half load — that's enough window to shut down gracefully or ride through a brief utility event without data loss or corrupted video frames.

Technical Highlights:

• Double-conversion topology with 0 ms transfer time: Every connected device sees continuous clean 120V sine wave. No switching delay means your encoders, network interfaces, and recorders never see a power gap — essential for surveillance systems where a 5ms hiccup can cause video artifacts or dropped frames.
• 12-minute half-load runtime: A compact NVR + PoE switch pulling 500W will run for 12 minutes on battery. That's the critical window between power loss and graceful shutdown — long enough to execute emergency sequences, notify operations, or wait out a utility dip.
• 8 outlets in pairs, 710J surge protection: Paired outlet switching prevents accidental overload and gives you granular control over load shedding. The 710J surge spec stops transient spikes from lightning or utility faults — not exotic protection, but standard defense for electronics worth protecting.
• Sealed lead-acid batteries, 4-hour recharge to 90%: Two 12V/9Ah cells deliver predictable performance. Recharge cycle is quick enough for frequent power events common in unstable utility environments. Plan battery replacement every 3–4 years in 24/7 surveillance deployments.
• SNMP and PowerPanel® Business Edition monitoring: Real-time visibility into load, battery health, and remaining runtime. Traps alert your NOC to low-battery conditions before the lights go out — essential for any unattended site.

Deployment Considerations:

• The OL1KRTHD is sized for brief grid outages (seconds to minutes), not sustained blackouts. For remote sites with frequent or long-duration outages, you must pair this with a generator or solar system — the UPS handles the switching logic and ride-through, but it cannot sustain load indefinitely.
• The 10-foot power cord reaches most wall outlets, but avoid chaining multiple UPS units or daisy-stacking onto existing power strips — that cascades failure modes and defeats the protection topology. Give the OL1KRTHD its own dedicated circuit if possible.
• Battery replacement is a scheduled maintenance task. At 3–5 years, plan $150–$250 for a new battery set. Keep spares on hand in high-cycle environments; a dead UPS battery in the middle of a power event is a catastrophic failure, not a minor inconvenience.

This is the right choice for control rooms, network closets, and compact surveillance deployments where clean power and zero-transfer-time switching are non-negotiable. It's not glamorous, but it works — and it keeps the most critical parts of your system alive when the grid hiccups.
