Product Features
Technical Overview
This SmartOnline UPS employs double conversion online topology, continuously converting incoming AC power to DC and back to clean AC output, isolating connected equipment from all common power problems including surges, sags, harmonics, and frequency variations. The system operates with a unity output power factor of 1.0, enabling support of more equipment without overloading the UPS capacity.
A 5-inch touchscreen color LCD provides comprehensive local monitoring and control, displaying real-time status, alarms, and system diagnostics. Four LED indicators visually signal AC mode, bypass, battery, and fault conditions for at-a-glance assessment. The DC system operates at 120V DC, and the unit includes overload protection and schedulable high-efficiency economy mode operation to reduce energy consumption during off-peak hours.
This section brings together practical product details such as Plug/Connector Type, Receptacle Type, Transfer Time, Load Capacity (VA), so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
