EVI 3000VA / 2700W Rack Mount Online Single Phase UPS
A server rack rarely stays at one server for long. Add a second host, a storage array, a few managed switches, and a security appliance, and the combined power draw quickly moves beyond what a 1000VA or 2000VA UPS can comfortably support with any real headroom. The EVI 3000VA / 2700W Rack Mount Online Single Phase UPS (EP-UPS3000UC13OR) sits at the top of EVI’s compact rack-mount online range, delivering the highest capacity in this family while keeping the same true double-conversion protection and compact 2U footprint that makes the whole lineup practical for real server rooms.
This is genuine enterprise-class protection scaled for multi-server racks, telecom cabinets, and point-of-sale infrastructure that has outgrown smaller rack-mount UPS units — without stepping up to the size and cost of EVI’s larger tower or 3-phase systems.
The Top of EVI’s Compact Rack-Mount Online Family
At 3000VA / 2700W with a full 1.0 output power factor, the EP-UPS3000UC13OR delivers genuinely more usable power than EVI’s 1000VA and 2000VA rack-mount siblings, built around a larger internal battery configuration to match. Where the 1000VA model runs on 2 x 9Ah batteries and the 2000VA model on 4 x 9Ah batteries, this 3000VA unit steps up to 6 x 9Ah batteries, giving it proportionally more stored energy alongside its higher output capacity — and an optional matching battery extension unit is available for facilities that need to push runtime even further.
This scaling matters directly for multi-device racks: as more servers, switches, and storage devices get added to a single UPS, both the power capacity and the battery reserve need to grow together, not just one or the other.
True Online Double Conversion with Zero Transfer Time
Continuous AC-DC-AC conversion delivers pure sine wave output with zero transfer time between grid and battery power, isolating every connected device in the rack from voltage sags, surges, and frequency instability. For a rack running multiple servers simultaneously, this matters more than it might for a single device — an unexpected reboot event doesn’t just affect one system, it can cascade across networked services, storage replication, and clustered applications all sharing the same rack.
Wide Input Tolerance and Efficient Power Delivery
Operating across a wide input voltage range of 110 to 300 Vac with input power factor correction (PFC) rated above 0.99, the EP-UPS3000UC13OR tolerates East Africa’s grid instability without unnecessarily switching to battery power, extending battery service life across its operating period. A full 1.0 output power factor ensures the entire 2700W rating is genuinely available to connected equipment, rather than held back by reactive power losses the way lower power-factor units are.
Smart Charging for Larger Battery Configurations
Charging current is selectable between 1A and 2A, with the 2A setting specifically supported for configurations running two groups of installed batteries — a genuinely relevant option at this capacity tier, where facilities are more likely to deploy expanded battery configurations for longer runtime requirements.
Lithium Battery and BMS Ready
The EP-UPS3000UC13OR supports both traditional sealed lead-acid batteries and modern lithium batteries with Battery Management System (BMS) integration. At this higher capacity tier, where battery bank replacement costs scale up accordingly, keeping the lithium upgrade path open represents a meaningfully larger long-term saving than it does for smaller units, as lithium battery costs continue to decline relative to their cycle-life advantages.
Low Priority Load Disconnection for Multi-Device Racks
The low priority load disconnection function becomes especially valuable in a rack running several devices of varying criticality. During an extended outage, the system automatically sheds non-essential connected equipment — a secondary switch, a less critical monitoring appliance — preserving battery runtime for the primary servers and storage systems that actually need to stay online.
Generator Compatible with Emergency Power Off
Full generator compatibility ensures reliable operation alongside backup generators during startup and load transition periods, while the Emergency Power Off (EPO) function provides immediate, safe shutdown capability for emergency situations — a standard requirement in professional data center and telecom deployments.
ECO Mode for Efficient Multi-Device Operation
ECO mode allows the unit to run in a higher-efficiency state during stable grid conditions, an efficiency gain that compounds meaningfully at this capacity tier given the larger continuous load typically running through the unit, while retaining instant full double-conversion protection the moment power quality degrades.
Selectable Output Voltage and 8 IEC C13 Outlets
Selectable output voltage across 200, 208, 220, 230, and 240 Vac allows the unit to adapt to regional equipment requirements without needing a different model per deployment. Eight IEC C13 outlets provide ample connectivity for a genuinely populated rack, supporting multiple servers, switches, and storage devices from a single, centrally managed unit.
The Cost Case for Right-Sizing a Growing Rack
Running a genuinely multi-server rack off an undersized UPS risks either overload trips during peak demand or a battery bank that depletes far faster than expected during an outage. At 2700W with a proportionally sized 6-battery bank, the EP-UPS3000UC13OR removes both risks for a rack that has grown past two or three devices, at a cost that remains modest against the price of a single corrupted database or a rack-wide outage affecting several networked services simultaneously.
Rotating LCD Display and Comprehensive Communication
A rotating, backlit LCD display provides at-a-glance monitoring of load percentage, battery status, frequency, and alert conditions from any rack angle. Standard USB and RS232 ports support direct PC-based monitoring and management software integration, with an optional SNMP card available for organizations managing multiple servers or branch offices that need centralized, network-based monitoring across their infrastructure.
