CyberPower PR1500RT2UCN Line-Interactive Sine Wave Rack/Tower UPS 1500VA/1500W
Overview
The CyberPower PR1500RT2UCN is a 1500VA / 1500W line-interactive UPS delivering true sine wave output — the power quality demanded by active PFC power supplies found in NVRs, rack servers, PoE switches, and access control panels. Where a simulated (stepped-approximation) waveform triggers overload shutdowns or hum in sensitive electronics, the PR1500RT2UCN outputs clean sine wave AC both on battery and regulated utility power, making it a straightforward fit for any rack that mixes compute and IP security hardware.
The unit operates in a 2U rack or tower orientation, covers a wide input voltage window from 75 V to 149 V before switching to battery, and delivers all 1500 W of capacity at a unity power factor (PF 1.0) — meaning the VA and watt ratings are identical and there is no derating calculation needed when sizing loads.
Key Features
- True Sine Wave Output: Generates clean sinusoidal AC rather than a stepped approximation. Active PFC power supplies — standard in modern NVRs, rack servers, and managed switches — require sine wave input to operate correctly and avoid nuisance shutdowns or premature capacitor wear. This is the primary differentiator from entry-level line-interactive UPS units at a lower price point.
- 1500 VA / 1500 W at Unity Power Factor: With a power factor of 1.0, every VA of rated capacity translates directly to usable watts. A 1500 VA unit with PF 0.9 delivers only 1350 W; the PR1500RT2UCN delivers the full 1500 W, so load calculations are straightforward with no hidden derating.
- Wide Input Voltage Window (75–149 V): Line-interactive voltage regulation handles browndowns as low as 75 V and spikes up to 149 V through the automatic voltage regulator (AVR) without transferring to battery. Tighter sites that see frequent voltage sags preserve battery cycle life rather than burning through charge/discharge cycles on every brownout.
- 2430-Joule Surge Energy Rating: The integrated surge suppressor absorbs 2430 joules — roughly 4–5× the rating of a standard power strip. This matters in environments where switching transients, lightning proximity, or HVAC cycling introduce high-energy spikes on the circuit.
- 6 ms Transfer Time to Battery: When utility power falls outside the operating window, the UPS switches to battery in 6 milliseconds. Most active PFC supplies bridge that gap without a power interruption; most servers and NVRs maintain operation without a glitch.
- 8 Surge + Battery Backup Outlets (NEMA 5-15R): All eight outlets provide surge protection; all eight provide battery backup. There are no
