Description
The Eaton FERRUPS FE5.3 Tower UPS (model FJ100LB1G1I2A0B) delivers advanced, configurable power protection through patented ferroresonant technology, ideal for sensitive IT, telecom, and mission-critical equipment. With 5300VA / 3.7kW capacity, this line-interactive UPS ensures superior voltage regulation, eliminates harmonics, and isolates connected loads from power anomalies like surges, spikes, and lightning.
Equipped with galvanic isolation, active voltage regulation, RS-232 connectivity, and built-in diagnostics, the FE5.3 keeps systems running smoothly without prematurely draining battery reserves. The included Eaton Software Suite with SNMP/WEB readiness and LAN-safe management tools adds an extra layer of intelligent control and remote management.
