The East EA903PS 3000VA/2700W Online Double Conversion UPS is an advanced, high-frequency power protection solution engineered for demanding enterprise environments, server rooms, and critical IT infrastructure.

As a true online UPS, it continuously converts AC input to DC and back to pure sine wave AC output, isolating connected devices from all power disturbances, including surges, sags, spikes, and noise for zero transfer time and ultimate reliability. With an impressive wide input voltage range of 110-300V (full load) and 277-485V (no derating), it excels in unstable power grids, extending battery life by minimizing discharge cycles.

Output power factor of 0.9 supports modern high-density loads efficiently, while features like short circuit/overload protection, cold start capability, and powerful background charging ensure uninterrupted operation. The tower design with LCD display offers real-time monitoring and configuration, making it ideal for telecom, finance, and data processing applications where downtime is not an option. RoHS-compliant and user-serviceable, the EA903PS delivers scalable, low-maintenance power continuity at an affordable price.
