The VECHO VEC-LT1200VA-1272 is a line-interactive uninterruptible power supply designed for personal computer installations and compa working environments. It provides a rated capacity of 1200 VA / 720 W and delivers simulated sinewave output during battery operation. Its integrated boost-and-buck automatic voltage regulation helps stabilize a wide 140–300 VAC input range. The UPS also supports cold start, automatic restart when AC power recovers, off-mode charging and intelligent battery recharging. Key Features 1200 VA / 720 W Capacity: Provides power protection within the specified apparent-power and active-power limits. Line-Interactive Operation: Uses simulated sinewave output while operating from battery power. Automatic Voltage Regulation: Two boost stages and one buck stage help stabilize incoming AC voltage. Wide Input Range: Supports 140–300 VAC input at 50/60 Hz with automatic frequency sensing. Dual-Battery Configuration: Uses two 12 V, 7 Ah batteries with a typical recharge time of 6–8 hours to 90% capacity. Integrated Protection: Includes short-circuit, overload, overcharge and over-discharge protection.
