CyberPower PR1000RT2UC 1000VA/1000W Sine Wave 2U Rack UPS
Overview
The CyberPower PR1000RT2UC is a 1000VA/1000W line-interactive rack UPS built for small server rooms, network closets, and surveillance head-end racks where power continuity and clean sine wave output matter. At 2U, it fits into standard 19-inch racks without consuming more real estate than necessary. If you're protecting NVRs, switches, or access control servers that depend on stable power to maintain recording and access integrity, the PR1000RT2UC is worth understanding before you spec a lesser unit.
Key Features
- True Sine Wave Output: The PR1000RT2UC delivers pure sine wave power during both utility and battery operation. Active PFC power supplies — common in modern NVRs, servers, and managed switches — require clean sine wave to function correctly on battery. Square wave or simulated sine wave UPS units can cause these loads to fault, shut down, or run at reduced efficiency. With a power factor of 1.0, the full 1000W rated load matches the 1000VA input, so capacity calculations are straightforward.
- Line-Interactive Topology: Rather than switching to battery every time voltage drifts, the PR1000RT2UC uses automatic voltage regulation (AVR) to correct input voltages anywhere from 75V to 149V without drawing down battery. For facilities where brownouts or utility sags are common, this extends battery life significantly — the unit compensates without ever touching stored capacity.
- 2430 Joule Surge Energy Rating: 2430J is a meaningful number for rack deployments. Most basic surge strips protect at 300–900J. At 2430J, the PR1000RT2UC absorbs large transient spikes without sacrificing the protection rating of the MOV network over time. Combined with EMI/RFI noise filtering, connected equipment sees a much cleaner power envelope than raw utility power provides.
- 6 ms Transfer Time: When utility power fails, the PR1000RT2UC switches to battery within 6 milliseconds. Most modern power supplies have enough internal capacitance to bridge a 6ms gap without any output interruption to the connected load — recordings stay continuous, access logs don't gap, and servers don't register a power event.
- Wide Input Voltage Window (75–149V): Accepting input from 75V to 149V means the PR1000RT2UC tolerates browndowns that would drop simpler units to battery immediately. In older commercial buildings, branch circuit voltage can sag well below 100V under load — this unit handles it without an alarm.
- 47–63 Hz Input Frequency Range: The broad frequency acceptance makes this unit compatible with both standard North American 60Hz utility and generator-sourced power, which often runs at a slightly variable frequency. If your site uses a generator as primary or backup utility, this matters.
- Audible Alarm System: Four distinct alarm conditions — on-battery, fault, low battery, and overload — give on-site personnel immediate situational awareness without requiring software. For unmanned remote closets, on-battery and low-battery alarms are the critical ones: they trigger before a graceful shutdown window closes.
- EMI/RFI Filtering: Network and surveillance equipment is sensitive to line noise. The integrated EMI/RFI filter suppresses conducted interference on the AC line, reducing the chance of network packet errors or camera signal artifacts caused by switching noise on shared branch circuits.
Integration & Compatibility
The PR1000RT2UC uses a NEMA 5-15P input plug on a 10-foot cord, feeding eight NEMA 5-15R output receptacles — standard North American 15A outlet format. This suits typical rack equipment with IEC-to-5-15 or direct 5-15 power cords. The 2U rackmount form factor fits standard EIA 19-inch racks. The PR1000RT2UC supports cloud-based monitoring and management, allowing remote visibility into UPS status, runtime estimates, and alarms from off-site — relevant for managed service environments or multi-site surveillance deployments where physical access to each rack is limited. For rack UPS and power protection planning in surveillance environments, matching UPS runtime to camera and NVR load calculations is the critical design step — this unit's 1000W capacity should be budgeted against total connected load with runtime requirements in mind. Browse the full CyberPower power protection line for higher-capacity or tower-format alternatives. For switch and NVR power planning, see the PoE switch category to understand the total power draw you're protecting. If you're designing a full surveillance rack, pair this with a network video recorder sized for your camera count — the combined load determines whether 1000W is sufficient or you need to step up.
Frequently Asked Questions
Q: Does the PR1000RT2UC output true sine wave on battery, or only simulated sine wave?
A: The PR1000RT2UC delivers true sine wave output during both utility and battery operation. This matters for active PFC power supplies found in NVRs, servers, and managed switches — those loads require sine wave to run correctly on battery without shutting down or generating faults.
Q: What input voltage range does the PR1000RT2UC support?
A: The PR1000RT2UC accepts input voltages from 75V to 149V through its automatic voltage regulation (AVR) circuit, correcting low or high voltage conditions without switching to battery. This makes it suitable for environments with brownouts or unstable branch circuit voltage.
Q: How many outlets does the PR1000RT2UC provide and what type are they?
A: The PR1000RT2UC provides 8 NEMA 5-15R output receptacles — standard 15A North American outlets. The input is a NEMA 5-15P plug on a 10-foot cord.
Q: What is the transfer time from utility to battery on the PR1000RT2UC?
A: Transfer time is 6 milliseconds. Most modern power supplies bridge this gap without any interruption to connected equipment, so NVRs and servers typically see no power event during the switch.
Q: Can the PR1000RT2UC be used with generator power?
A: Yes. The PR1000RT2UC accepts input frequencies from 47 to 63 Hz, which covers the slight frequency variation common in generator-sourced power. Standard North American utility runs at 60 Hz; this unit handles the variance without faulting.
Q: What is the surge energy rating on the PR1000RT2UC?
A: The PR1000RT2UC is rated at 2430 joules of surge energy absorption. This is substantially higher than consumer-grade surge strips and is designed to protect rack-mounted equipment from transient voltage spikes while maintaining long-term protection effectiveness.
The detail I always check first on a rack UPS spec sheet is whether the sine wave output applies only on utility or also on battery — the PR1000RT2UC delivers true sine wave in both modes, which is the non-negotiable requirement for any rack populated with active PFC power supplies. If you're protecting a surveillance NVR, a managed PoE switch, or a server with a modern switching PSU, this matters more than runtime estimates.
Technical Highlights:
- True Sine Wave (Both Modes): Power factor of 1.0 means the 1000VA and 1000W ratings are identical — no derating calculation needed when sizing load. Active PFC PSUs in NVRs and switches will operate normally on battery without fault or shutdown.
- AVR Input Window (75–149V): Automatic voltage regulation corrects brownouts from 75V and overvoltages up to 149V before they reach battery — a meaningful longevity benefit in older commercial facilities where branch circuits sag under load.
- 2430J Surge Rating: At more than double what most basic rack PDUs offer, this rating gives meaningful transient absorption headroom. Combined with integrated EMI/RFI filtering, connected network equipment sees cleaner power than most branch circuits deliver unfiltered.
Deployment Considerations:
- The 10-foot input cord and NEMA 5-15P plug assume a standard 15A branch circuit. Verify your rack PDU or wall receptacle is 5-15R before spec'ing — if your facility uses 20A circuits with 5-20R receptacles, you'll need an adapter or a different input configuration.
- Runtime on a full 1000W load will be short — budget realistically. For surveillance racks where graceful shutdown of an NVR may take 2–3 minutes, calculate your actual connected load (NVR + switches + cameras on local power) and confirm the runtime curve from the manufacturer's specifications before assuming this unit covers your shutdown window.
For a network closet or surveillance head-end rack carrying an NVR, a managed PoE switch, and an access control server — total connected load in the 400–700W range — the PR1000RT2UC delivers the clean sine wave output and AVR correction those loads need, with enough surge absorption to handle the transients common on commercial branch circuits.
