Zebronics Zeb-U735 600VA Line Interactive UPS — 360W | AVR | Simulated Sine Wave | Generator Compatible

The Zebronics Zeb-U735 is built for home users, students, and small office professionals who need reliable power backup and voltage regulation for desktop PCs, monitors, routers, CCTV DVRs, and other sensitive electronics during power outages, voltage sags, surges, and brownouts. It is well-suited for home desktop setups, home offices, small business workstations, and any environment with unstable or fluctuating mains power where equipment protection and continuity during short outages are priorities.

The Zeb-U735 operates as a line interactive UPS — actively regulating output voltage during brownouts and over-voltages via Double Boost AVR without switching to battery, preserving battery life for actual power outages. The wide input voltage range of 140–300V accommodates the highly variable mains conditions common across India, ensuring connected equipment receives stable 230V ± 10% output regardless of input fluctuation. A fast 4–8ms transfer time from mains to battery ensures connected equipment experiences no interruption or restart during switchover. Simulated Sine Wave output provides sufficient power quality for standard desktop PCs, monitors, routers, and similar loads. Three output sockets provide connectivity for a complete basic desktop setup. The internal 12V 7Ah sealed maintenance-free battery recharges at 1A, reaching 90% capacity within 6–8 hours after a full discharge. Microcontroller-based intelligence manages all UPS functions including auto-restart when AC power recovers, no-load auto-shutdown in battery mode to conserve battery charge, and generator compatibility for deployments with backup generator power. Audible alarms with distinct beep patterns for battery mode (every 10 seconds), low battery (every 1 second), overload (every 0.5 seconds), and fault (continuous) — alongside three LED indicators for AC mode (green), battery mode (orange blinking), and fault mode (red) — provide clear at-a-glance and audible status awareness. Overload, short circuit, over-discharge, and over-charge protections safeguard both the UPS and connected equipment.

Special Features
Double Boost AVR, Wide Input Range, Auto-Restart on AC Recovery, No-Load Auto Shutdown (Battery Mode), Generator Compatible, Microcontroller Based

System Requirements: Compatible with standard 3-pin Indian power outlets (220–240V AC, 50/60 Hz); 3 output sockets support a desktop PC, monitor, and router or similar combination within the 360W maximum load; connect only non-inductive loads (desktop PCs, monitors, routers, networking devices) — not suitable for air conditioners, refrigerators, laser printers, or other high-inrush inductive loads; generator compatible for shared generator power environments

Setup: Plug the UPS into a standard 3-pin wall outlet; connect equipment to the 3 output sockets; the UPS automatically manages AVR and battery switchover without manual intervention; the battery is pre-installed and begins charging on first power-on — allow 6–8 hours for full initial charge before first use in a power outage scenario

Mounting Options: Standard desktop floor or table placement; compact 101×280×142mm footprint for desk or adjacent cabinet placement

Usage Environment: Ideal for home desktop PCs, home office workstations, routers and networking equipment, CCTV DVRs, student setups, and small business environments requiring reliable 600VA line interactive power backup with AVR and generator compatibility
