R Series 1/2/3 kVA

Features & Benefits

Availability

• True online double-conversion topology provides zero transfer time to ensure maximum protection of the equipment
• Watch-dog design of the DSP (Digital Signal Processor) increases reliability
• Cold-start capability provides temporary battery power when the utility power is out
• Operating temperature tolerance up to 50°C ensures critical loads’ continuity
• The Maintenance Bypass Box offers load continuity during battery replacement or other upgrades

Flexibility

• Compact dimensions meet the needs of different rack cabinets
• Convertible rack and tower configuration in 2U size cabinet
• Excellent local communications through rotatable LCD display
• Intelligent management software connectivity via RS232, mini slot or USB port

Low Total Cost of Ownership

• Wide input voltage range reduces the chance of using the battery and extends battery life
• Intelligent battery management sustains battery life and performance
• High output power factor of 0.9 provides more real power to critical loads
• High input power factor (pf > 0.99) and low harmonic distortion (iTHD < 3%) save upstream investment
• Up to 93% AC-AC efficiency and 96% efficiency in ECO mode results in marked energy cost savings
• Fan speed control by load level and room temperature optimizes performance
