KEY FEATURES & BENEFITS
Automatic Bivolt Input & Dual Voltage AC Output Adaptability
Engineered specifically for dual-voltage grid infrastructure (120V / 220V AC auto-sensing input). Automatically detects incoming utility voltage across 93–145Vac or 186–253Vac windows, delivering regulated 120Vac or 220Vac output without requiring manual voltage switching or external transformers.
CPU-Controlled 2-Step Automatic Voltage Regulation (AVR)
Integrated Digital CPU microcontroller manages a double-stage AVR boost and buck circuit. Smooths out severe voltage sags and power surges automatically, maintaining stable 120V/220V AC output to connected equipment without discharging internal backup batteries during routine grid fluctuations.
Heavy-Duty Internal Lead-Acid Battery Array (2–6ms Transfer Time)
Houses high-capacity 12V 7Ah or 12V 9Ah internal sealed lead-acid battery packs (ranging from 1 to 4 pcs). Delivers ultra-fast 2–6ms typical transfer time to PWM inverter mode upon utility failure, preventing cashier freezes, server crashes, or data corruption.
Offline Automatic Charging & Auto-Restart on AC Recovery
Intelligent offline charging automatically recharges internal batteries to 90% capacity within 4 to 6 hours even when the UPS unit is powered off. Features seamless Auto-Restart logic, automatically booting up connected loads as soon as AC mains power is restored after long blackouts.
Comprehensive Triple Circuit Protection & Mute Function
Equipped with hardware protection against battery low-voltage discharge, output overload, and short circuits. Features a convenient silence setup button to mute audible buzzer alarms during night-time operation or quiet office environments.
3-LED Status Telemetry Panel & Optional USB/Network Protection
Front panel integrates clear BACKUP (Red), NORMAL (Green), and OVERLOAD (Yellow) LED status indicators for instant operational visual inspection. Supports optional RJ11/RJ45 line surge protection and USB communication port for smart telemetry monitoring.
