APC Smart-UPS 3000VA 2700W Online Double-Conversion UPS
R16 675.00 incl. VAT
The APC Smart-UPS 3000VA (SMT3000I) is the gold standard for South African server room and critical infrastructure protection — an online double-conversion UPS that regenerates perfect 230V / 50Hz power from the battery at all times, providing absolute zero-transfer-time switchover and total isolation from the grid.
Unlike line-interactive units, the online double-conversion topology means your servers and medical equipment never see raw grid power — only clean, conditioned, sine-wave output regenerated by the inverter. Ideal protection against SA’s load shedding, voltage spikes, frequency deviations, and harmonic distortion.
2,700W output, runtime extendable with external battery packs. Network-manageable via NMC card (optional). USB and RS232 communication. APC’s global 3-year warranty with local SA service centre support. Price excludes VAT and external battery packs.

What Is the APC Smart-UPS 3000VA?
The APC SMT3000I is a 3000VA (2,700W) online double-conversion UPS designed for server rooms, data centres, medical equipment, and any application where even a 4ms transfer time is unacceptable. “Online double-conversion” means 100% of output power passes through the UPS’s rectifier and inverter at all times — the battery is continuously in the power path, providing genuine zero-millisecond transfer time when the grid fails.

Online Double-Conversion vs. Line-Interactive — What’s the Difference?
Line-interactive UPS units (like the Mecer 3kVA) switch to battery in 2–10ms when the grid fails — fast enough for most computers and office equipment, but potentially problematic for servers, VMware hosts, NAS arrays under write load, and medical devices. The APC Smart-UPS SMT3000I never switches — it’s always on battery from the inverter’s perspective. The transition from grid to pure battery is instantaneous and invisible to connected equipment.
Perfect Power Quality for SA’s Grid Problems
SA’s grid suffers from voltage fluctuations, frequency deviations (normal is 50Hz, grid can deviate by ±2Hz during demand peaks), harmonic distortion from industrial loads, and transient spikes from switching. The SMT3000I’s double-conversion topology filters all of these at the rectifier stage — connected equipment sees only clean 230V/50Hz sine wave regardless of what the grid is doing.
Network Management
Insert an optional APC AP9641 NMC card into the SmartSlot to enable SNMP monitoring, email alerts, and remote shutdown via web interface or network management software — essential for enterprise environments with multiple UPS units to manage across SA’s load-shedding schedule.
