CyberPower OLS3000ERT2UA - 3 kVA / 2.7 kW Online (Double Conversion) UPS – Rack/Tower (2U)

The CyberPower OLS3000ERT2UA is a 3000 VA / 2700 W online double-conversion UPS designed for professional server rooms, data centres, and mission‑critical infrastructure. With pure sine‑wave output and 0 ms transfer time, it ensures seamless, continuous power protection for sensitive equipment including NAS, servers, DVRs, point-of-sale systems, and industrial automation setups.

Power Performance & Efficiency

• Capacity: 3000 VA (2700 W) with a power factor of 0.9

• Total harmonic distortion (THD): ≤ 3–5% depending on load type

• Eco Mode Efficiency: Up to ~95%, reducing energy use and operating costs

• Compatible with generators, making it ideal for hybrid or backup power systems

Input & Output Specs

• Input voltage: Nominal 230 V AC, adjustable range from 190 to 300 V (adaptive down to 80 V under lighter load)

• Output voltage: Configurable to 208/220/230/240 V ± 1% with pure sine output at 50/60 Hz ± 0.5%

• No-transfer switching ensures continuity of service for critical loads

Battery & Runtime

• Battery: Six 12 V sealed lead‑acid modules (72 V, 9 Ah total); expandable via optional extended battery modules (EBMs), auto‑detected for runtime estimation

• Runtime: Approx. 4 minutes at full load, 11 minutes at half load, 6 minutes at ~2025 W, 31 minutes at ~675 W 

• Recharge time: Around 4 hours for full battery recovery

• Hot‑swappable replacement battery packs supported; start-on-battery and smart battery management ensure longevity and uptime

Design & Build

• Form factor: Rack-mountable 2U chassis (convertible to tower) with metal housing, colour: black; includes rails, ears, screws, cables

• Dimensions & weight: 438 × 610 × 88 mm; ~27.6 kg net, ~30.8 kg shipping weight 

Control & Management

• Connectivity: USB and RS‑232 (DB‑9) ports, plus an EPO (Emergency Power Off) port. Optional SNMP/HTTP card (e.g., RMCARD205) enables network monitoring and alerts 

• User interface: Rotatable colour LCD panel displays operation mode, battery and load status, logs, alarms and settings — ideal for rack environments

Protection & Features

• Topology: Double-conversion (online) safeguards against all power issues—surges, spikes, brownouts, swells—with surge energy rating ~440 J

• Surge/EMI/RFI filtering, overload protection with circuit breaker and fuse, and Smart Battery Management incorporated

• Variable-speed fans adjust based on thermal load to minimize noise (≈ 45 dBA) while maintaining cooling efficiency
