The compact design, clear status indicators, and efficient power management make this UPS an ideal solution for environments with unstable electrical supply.
Product Features
Enhanced power capacity
Support multiple high-demand devices simultaneously with 1200VA/650W capacity that provides extended runtime for computers, monitors, networking gear, and peripherals during power outages. The substantial power rating enables continued operation of essential equipment or graceful system shutdowns, protecting data and productivity. This capacity is well-suited for small business environments, home offices, and entertainment systems requiring reliable power protection.
Advanced voltage regulation
Maintain optimal power quality with Boost AVR technology that automatically corrects under-voltage conditions without draining battery power. The voltage regulation stabilizes input power between 140-300V, protecting connected equipment from brownouts and overvoltages that can damage sensitive electronics. This intelligent feature significantly extends battery life by minimizing unnecessary battery usage during common voltage fluctuations.
Flexible outlet configuration
Accommodate diverse equipment with four universal outlets that support various plug types and one IEC C13 outlet for standard computer and peripheral connections. The mixed outlet configuration enables strategic power management by allocating battery backup to critical devices while providing surge protection to less essential equipment. The universal outlets eliminate the need for adapters, ensuring compatibility with devices from different regions.
Comprehensive surge protection
Safeguard connected electronics with 255-joule surge protection that defends against power spikes, electrical noise, and lightning-induced surges. The robust surge suppression covers all outlets, preventing damage to valuable electronics from common power disturbances. This protection is particularly valuable in areas with frequent electrical storms or unstable power infrastructure.
Cold-start capability
Maintain functionality during extended utility outages with cold-start capability that allows the UPS to be powered on from battery alone when no AC power is available. This feature enables temporary operation of critical devices during prolonged blackouts, providing additional flexibility in emergency situations. The cold-start function enhances the UPS’s utility in environments with unreliable grid power.
Intelligent battery management
Optimize battery performance and lifespan with advanced charging technology that ensures efficient recharging within 8 hours and provides 3-5 years of typical service life. The battery management system includes automatic self-testing and status monitoring to ensure reliable performance when needed. The sealed lead-acid battery requires no maintenance while delivering consistent backup power.
