EVI 10000VA / 9000W Tower Online 3 Phase UPS
Three-phase power failures do not politely announce themselves. A single phase drops, a motor stalls mid-cycle, a production line grinds to a halt, or an entire server hall goes dark in the time it takes to blink. For industrial operations, data centers, and facilities running genuine three-phase infrastructure, single-phase UPS protection is not just inadequate — it is a liability waiting to surface at the worst possible moment. The EVI 10000VA / 9000W Tower Online 3 Phase UPS (EP-UPS10000Y33OT) was built specifically for organizations that cannot afford to gamble on three-phase continuity.
This is a true 3-phase input and 3-phase output online double-conversion UPS with DSP control, inbuilt batteries, and zero transfer time — engineered to keep balanced, three-phase-dependent systems running exactly as designed, uninterrupted, through every grid fault Kenya’s power network can throw at it.
True 3-Phase Input and Output: Power That Matches Your Equipment
Many facilities make the costly mistake of protecting three-phase loads with stacked single-phase UPS units, introducing phase imbalance risk and unnecessary complexity. The EP-UPS10000Y33OT eliminates that compromise entirely, delivering genuine 3-phase input and 3-phase output at 10000VA / 9000W (0.9 power factor), matched precisely to the electrical characteristics of three-phase motors, industrial control panels, HVAC systems, and enterprise server infrastructure.
With DSP (Digital Signal Processing) control governing the charging, rectifier, and inverter stages through fully digital control technology, voltage regulation and transient response are managed with a level of precision that older analog-controlled UPS systems simply cannot match. The practical result: cleaner sine wave output, tighter voltage tolerance, and faster reaction to load changes.
Zero Transfer Time: The Difference Between Downtime and No Downtime
Output transfer time of 0 ms means there is no gap, no flicker, and no interruption when switching between grid power and internal battery power. For continuous industrial processes, precision manufacturing equipment, and always-on data infrastructure, this single specification often determines whether an outage becomes a non-event or a costly production failure requiring hours of recovery and re-calibration.
N+X Parallel Redundancy: Scale Capacity or Scale Reliability
Growing operations rarely stay the same size, and neither should their power protection strategy. The EP-UPS10000Y33OT supports N+X parallel redundancy, allowing up to four units to operate together in parallel. This gives facility managers two powerful options within a single product line:
- Capacity expansion — combine multiple units to support growing three-phase load requirements as the business scales, without replacing existing infrastructure
- Redundancy protection — configure additional units purely for failover, so that if one UPS experiences a fault, the remaining units seamlessly absorb the load and operations continue without interruption
This parallel architecture makes the EP-UPS10000Y33OT a genuinely future-proof investment rather than a fixed-capacity purchase that gets outgrown within a few years.
Built for Kenya and East Africa’s Grid Extremes
Operating across a wide input voltage range of 208 to 478 Vac and a wide input frequency range of 40 to 70 Hz, this UPS is engineered to tolerate the kind of grid instability and generator frequency variation common across East African industrial parks, mining operations, and rural facility installations. Combined with power factor correction (PFC) technology and input current harmonic distortion held to just 3%, the system draws clean, efficient power from the grid or generator while protecting upstream infrastructure from harmonic pollution.
DC start functionality means the UPS can power up directly from battery power even without stable utility input present, a critical feature for facilities that need to bring systems online during extended outages, generator startup delays, or off-grid deployment scenarios.
Intelligent Charging and Inbuilt Battery Design
With inbuilt batteries and intelligent charging management, the EP-UPS10000Y33OT is engineered to optimize battery health over its service life rather than simply cycling batteries at a fixed rate regardless of grid conditions. This translates directly into fewer premature battery replacements and lower total cost of ownership across the warranty period. For facilities requiring longer backup windows, an optional external battery pack extends runtime well beyond the internal battery capacity, allowing the system to be tailored precisely to site-specific outage durations.
The Real Cost of Three-Phase Downtime
For a manufacturing line or industrial control room running 3-phase equipment, a single unplanned shutdown can mean spoiled batches, damaged motors from phase imbalance, hours of re-calibration, and missed delivery deadlines that ripple through supply chain commitments. Where such an event can easily cost hundreds of thousands of shillings in lost production and emergency technician callouts, a properly specified 3-phase online UPS with N+X redundancy represents a fraction of that cost as an ongoing insurance measure — one that pays for itself the first time a genuine grid fault would otherwise have taken the line down.
Enterprise Monitoring and Control at a Glance
A 7 inch touch LCD display puts real-time status, load percentage, battery health, and alarm conditions directly in front of facility staff, while a full suite of communication options keeps the UPS integrated into wider monitoring systems:
- USB and RS232 ports for direct PC-based monitoring and configuration
- RS485 port for industrial automation network integration
- Parallel port supporting the N+X redundancy configuration
- Dry contact interface for basic alarm and status signaling
- Optional SNMP card for remote, IP-based monitoring across a network operations center
- Optional relay card for expanded automation and third-party system integration
- Terminal ports for both input and output wiring, suited to permanent industrial installation
- Emergency Power Off (EPO) function for immediate, safe system shutdown during emergencies
Tower Form Factor for Industrial and Facility Environments
Unlike rack-optimized UPS units designed for dense server cabinets, the EP-UPS10000Y33OT is built in a tower form factor suited to plant rooms, industrial control panels, and facility electrical rooms where floor-standing equipment is the practical standard. This makes it a natural fit for manufacturing environments, water treatment facilities, telecom base stations, and any installation where three-phase distribution panels already dominate the room layout.
Backed by Confidence: 2-Year Warranty, 1-Year Battery Coverage
The EVI 10000VA / 9000W Tower Online 3 Phase UPS ships with a 2-year manufacturer warranty and 1-year battery warranty, giving facility managers and procurement teams the assurance that this is genuine capital equipment built for sustained industrial duty, not disposable electronics.
