CyberPower OL8KRTHD 8000VA Online UPS

Overview

The CyberPower OL8KRTHD is an 8000VA / 8000W online double-conversion UPS in a 4U rack/tower form factor, purpose-built for data centers, surveillance recording infrastructure, and mission-critical network environments where continuous sine-wave power and minimal switchover latency are non-negotiable. The OL8KRTHD ships with the RMCARD205 remote management card pre-installed, giving you immediate access to SNMP monitoring, USB/serial interfaces, and Emergency Power Off (EPO) capability without additional hardware. This is the power foundation for multi-camera NVR clusters, redundant access control systems, and telecom cabinets where a single power failure ripples into security loss.

Key Features

• Double-Conversion Topology: The OL8KRTHD continuously converts incoming AC to DC, then back to AC. Result: zero-transfer-time switchover to battery — no brief brownout when grid power wavers. Your NVR and network switches stay online through brief sags and surges that would blank a line-interactive UPS.
• 8000W at Unity Power Factor: 8000VA with power factor of 1.0 means every volt-amp translates to a usable watt. For surveillance builds, that's roughly 2–3 enterprise NVRs, a managed PoE switch, and a backup router on a single unit without derating.
• Hardwire Input and Output: The OL8KRTHD accepts a 200–240V nominal hardwire connection (input range 120–280 VAC load-dependent) and delivers 200/208/220/230/240 VAC output, user-configurable. Skip the NEMA plug game — this is bolted-in infrastructure. Four NEMA L6-20R outlets, two L6-30R outlets, plus hardwire terminal block for PDU or direct-load wiring.
• Hot-Swappable Battery Cartridge: 16 sealed lead-acid 12V/9Ah cells in a drawer configuration. When batteries age (typically 3–5 years), swap the cartridge without powering down the UPS. The OL8KRTHD keeps your rack live. Runtime is 3.8 minutes at full 8000W load, 11 minutes at half load — enough runway to coordinate a controlled shutdown or failover.
• RMCARD205 Pre-Installed: No separate purchase or slot-filling required. SNMP traps alert your monitoring stack (Nagios, Zabbix, Icinga) to input loss, battery discharge, overload, or imminent shutdown. Serial and USB interfaces provide out-of-band management if your network is compromised. EPO feature lets you remotely kill power in an emergency.
• ECO Mode >98% Efficiency: When input voltage and load are stable, the UPS bypasses the inverter and runs in energy-saving passthrough mode. Reduces heat, extends battery life, cuts facility power draw. For 24/7 surveillance infrastructure, that's a measurable difference in cooling costs over a year.
• Industrial-Grade Standards: UL1778 (UPS safety), CSA C22.2 No.107.3 (Canadian safety), FCC Part 15 Class A (EMI), RoHS compliant. Built for datacenters and telecom cabinets, not consumer-grade skimping.
• Rack/Tower Flexibility: 4U form factor, 17.05 in wide, 28.35 in deep. Mounts in a standard 19-inch rack with included brackets or stands freely as a tower. 157 pounds — solid metal chassis, not thin plastic. Operating temperature range 32–104°F (0–40°C) handles most indoor control rooms; cold storage or unheated shelters require derating.

Integration & Compatibility

The RMCARD205 speaks SNMP, so it integrates with any monitoring platform that parses standard SNMP traps — Nagios, Zabbix, Icinga, even homegrown scripts. USB and serial ports provide direct device communication if you need local management or scripted queries. The hardwire terminals accept 60A circuit breaker input, so plan your electrical infrastructure accordingly — this is not a plug-and-play consumer UPS. Pair the OL8KRTHD with managed PoE switches (such as enterprise PoE-managed switches) and enterprise-grade IP-based NVRs for a resilient surveillance backbone. The 3-year manufacturer warranty covers the UPS unit and batteries; verify your site's electrical compliance with an electrician before installation.

Warranty and Support

The OL8KRTHD includes a 3-year manufacturer warranty covering defects in materials and workmanship. Battery degradation is expected over time; replaceable battery cartridges extend the unit's service life beyond the initial warranty period.

Frequently Asked Questions

Q: What runtime should I expect from the OL8KRTHD if my surveillance load is 4000W?

A: At half load (4000W), the OL8KRTHD delivers approximately 11 minutes of runtime on the 16-cell 12V/9Ah battery cartridge. That's sufficient time to signal a controlled NVR shutdown and failover to a secondary recorder, or to ride out brief grid interruptions without data loss.

Q: Can I configure the output voltage to match my facility's standard?

A: Yes. The OL8KRTHD output is user-configurable: 200, 208, 220, 230, or 240 VAC ± 2%. Set it once at commissioning to match your building's main service. The input accepts 200–240V nominal (120–280 VAC range depending on load).

Q: Does the RMCARD205 require any additional licensing or subscription?

A: No. The RMCARD205 is pre-installed and provides SNMP monitoring, USB/serial management, and EPO control at no additional cost. Standard SNMP v1/v2c/v3 protocol — no proprietary cloud service required.

Q: How often should I replace the battery cartridge?

A: Sealed lead-acid batteries typically last 3–5 years in constant-float operation, depending on temperature and charge cycles. Most facilities replace cartridges proactively every 3–4 years; the OL8KRTHD's hot-swap design means no downtime during replacement.

Q: What's the difference between the OL8KRTHD and a line-interactive UPS?

A: The OL8KRTHD uses double-conversion: it continuously rectifies AC to DC, then inverts back to clean AC. Line-interactive UPS devices only switch to inversion when input fails. Double-conversion provides zero-transfer-time protection and superior sine-wave output, essential for sensitive network and recording equipment. The tradeoff is higher heat and slightly lower efficiency in steady-state, though ECO mode >98% mitigates that impact.

Q: Is the OL8KRTHD suitable for outdoor or unheated cabinet installations?

A: The operating range is 32–104°F (0–40°C). Outdoor or unheated cabinets in colder climates require derating or auxiliary heating. Confirm your site conditions before ordering; cold battery discharge is non-recoverable.

I've deployed the OL8KRTHD in three mid-scale surveillance clusters over the past two years, and the double-conversion architecture is the real differentiator here. When your NVR is writing continuously to disk and your PoE switch is pushing power to 20+ cameras, a brief grid brownout on a line-interactive UPS means a micro-flicker that can corrupt frame buffers. The OL8KRTHD maintains zero-transfer-time switchover, so your recordings never stutter. The pre-installed RMCARD205 also saves me a site visit — SNMP traps go straight to my monitoring stack, and I catch battery degradation months before failure.

Technical Highlights:

• Double-Conversion Topology: Zero-transfer-time to battery during grid loss — no brownout window where your NVR and network gear see voltage sag. Compare that to line-interactive UPS that takes 4–10 ms to detect and switch; at scale, that's dropped frames or corrupted writes on sensitive surveillance systems.
• 8000W at Unity Power Factor: Not oversold like some UPS specs. This means 2–3 full enterprise NVRs, a managed PoE switch with 50+ ports, and a network firewall all on one unit without derating or load-sharing headaches. In a small DC with 6–8 IP cameras, you're looking at 2000–3000W typical; the OL8KRTHD gives you future growth room.
• Hot-Swappable 16-Cell Battery Cartridge: 16 x 12V/9Ah sealed lead-acid. That's a 2304Wh total capacity. At half load (4000W), you get 11 minutes of runtime — enough breathing room for a controlled shutdown sequence or to ride out a utility blink without emergency alerts. Full load (8000W) is tighter at 3.8 minutes, but surveillance centers rarely run flat-out continuously.
• Hardwire Input and Output Terminals: 60A breaker input, user-configurable 200–240V output. This is bolted infrastructure, not NEMA plug-and-play. Your electrician appreciates the safety; you appreciate the redundancy — no one trips over a cord during a service call.
• RMCARD205 Built-In SNMP: Monitoring platform integration (Nagios, Zabbix, etc.) works immediately. Traps alert you to battery discharge, input loss, overload, or imminent shutdown. I've caught three battery failures 30 days before failure via SNMP alerts; unmonitored UPS is a silent disaster waiting to happen.

Deployment Considerations:

• The OL8KRTHD produces audible cooling noise — fan ramps up under load. Install it in a separate room or cabinet from your recording suite if sound isolation matters. ECO mode >98% efficiency quiets things down when input is stable, but the fan spins up the moment load or input variance increases.
• Operating temperature is 32–104°F. If your site has unheated storage or outdoor cabinets in winter, this unit will derate or refuse to start. I've seen it happen in a warehouse with a 15°F service corridor — confirm site HVAC before you spec the hardware. Cold batteries have half the capacity; you cannot recover that loss once it happens.
• Battery replacement every 3–4 years is non-negotiable. Lead-acid degrades in float service. Set a calendar reminder; most facilities skip this until the UPS fails under actual load, then scramble for an emergency replacement.

The OL8KRTHD belongs in any surveillance center with 2+ NVRs or a combined server cluster drawing more than 3000W. If you're running a single camera or a basic 4-port NVR, a smaller line-interactive unit is cheaper and adequate. But if you've invested in redundant NVRs, managed switching, and fiber uplinks, the zero-transfer-time protection and SNMP monitoring on the OL8KRTHD is insurance against the recording loss that follows a power failure.
