EVI 6000VA / 5400W Tower Online Single Phase UPS (EP-UPS6000Y11OT)

The EVI 6000VA / 5400W Tower Online UPS (EP-UPS6000Y11OT) is a high-capacity power protection solution engineered for environments where zero downtime is critical. Utilizing pure online double-conversion technology with DSP control, this tower UPS delivers clean, regulated sine wave power, completely isolating connected equipment from grid disturbances like surges, sags, spikes, and frequency variations. With a robust 6000VA/5400W capacity, wide input voltage range, and flexible configuration options—including selectable charging current, cold start capability, and expandable communication—it is the reliable backbone for small data centers, medical facilities, industrial controls, and telecom infrastructure.

Product Features

Pure Online Double-Conversion Technology

This UPS employs true online double-conversion topology, where incoming AC power is continuously converted to DC and then back to a perfectly regulated AC sine wave. This process ensures zero transfer time to battery during an outage and provides complete electrical isolation, protecting sensitive equipment from all forms of grid noise, voltage fluctuations, and harmonics.

High-Capacity Performance with Low Harmonic Distortion

Rated at 6000VA / 5400W with a 0.9 output power factor, this unit delivers substantial real power for demanding loads. Advanced DSP control keeps input current harmonic distortion below 3%, reducing stress on the upstream electrical system and ensuring cleaner, more efficient operation, especially when paired with generators or unstable mains power.

Wide Input Range and Generator Compatibility

Featuring an exceptionally broad input voltage window of 120–276 VAC and wide frequency ranges (45–55 Hz for 50Hz, 54–66 Hz for 60Hz), this UPS can handle severe grid fluctuations and operate seamlessly with backup generators. This makes it ideal for regions with unreliable power infrastructure or for use in mobile and industrial settings.

Advanced Configuration and Management

A rotating LCD display provides clear, readable status information from any installation angle. The system offers configurable 1A or 2A battery charging currents to optimize performance for single or dual battery bank setups. Built-in ECO mode improves efficiency during stable grid conditions, while comprehensive communication ports (USB, RS232) and optional cards (SNMP, Parallel, Relay) enable scalable monitoring and control.

Enhanced Safety and Operational Flexibility

The UPS includes critical safety features such as an Emergency Power Off (EPO) function via terminal block for immediate shutdown. It supports cold start capability, allowing the system to be powered on directly from the battery bank without mains input, which is vital for testing and emergency scenarios. A low-priority load shutdown function helps conserve battery runtime for the most critical equipment during extended outages.
