Expert Features
- 3000VA / 2700W Online Power Muscle: Delivers true online double-conversion output, ensuring zero-compromise power continuity for servers, workstations, and mission-critical systems.
- Pure Sinewave Output: Generates clean, utility-grade sinewave power for sensitive electronics, active PFC power supplies, and precision hardware.
- Wide Input Voltage Tolerance: Operates reliably across an extended 110–300Vac input range, minimizing battery usage in unstable power environments.
- High Input Power Factor (0.99): Active PFC design maximizes efficiency, reduces input current loss, and plays nicely with generators.
- Selectable Output Voltage: Supports 208V, 220V, 230V, and 240Vac output configurations to match diverse deployment requirements.
- Advanced Battery Architecture: Utilizes a high-voltage DC bus with six internal 12V batteries (standard unit) for stable energy delivery and efficient conversion.
- Smart Charging System: Optimized charger design extends battery lifespan and supports fast recharge cycles.
- Expandable Charging Current: Charging current can be expanded up to 12A on long-run configurations for extended backup scenarios.
- ECO Mode Operation: Improves efficiency during stable mains conditions without sacrificing protection.
- Cold Start Capability: Allows the UPS to power on directly from battery when utility power is unavailable.
- Generator Compatible Design: Engineered to operate smoothly with generator power sources.
- Intelligent Fan Speed Control: Dynamically adjusts cooling based on load and temperature to reduce noise and improve longevity.
- Versatile LCD Interface: High-visibility LCD provides real-time system status, electrical parameters, and alarm indicators.
- Comprehensive Protection Suite: Protects against short-circuit, overload, overheat, battery overcharge, battery over-discharge, output undervoltage, and fan faults.
