Key Features of Digital Uninterruptible Power Supply System With External Battery Connection

• Its In-Built AVR handles wild variations in mains voltage i.e. 135V to 280V to keep the output voltage within +7% of rated voltage.
• The UPS output is free from fluctuation, sags, surges, spikes, line noise and is fully regulated even on mains mode. The inverter output is phase synchronized with mains for smooth transfer and fast switching.
• The charger restores the battery 40% quicker than most UPS to ensure back-up is available in the event of power problems.
• Its cold start function allows starting up the computer and using battery power even when mains are absent.
• Option of connecting external batteries to the UPS for extended back-up.
• The UPS incorporates all the requisite safety features such as short circuit, overload, and battery deep discharge protection to provide safe and efficient working.
• The mode indicators of the UPS always keep the customers fully informed about the power condition.
