A.P.C. Smart-UPS systems deliver reliable uninterruptible power supply (UPS) protection for IT infrastructure, with the 1500VA and 2200VA models covering most business and critical-device needs. The choice depends on your power capacity requirement and rack-mount space—the 1500VA handles smaller deployments, whilst the 2200VA is built for larger server environments demanding higher fault tolerance.
Why A.P.C.?
A.P.C. (American Power Conversion) has been manufacturing UPS and power management solutions since 1981, specialising in industrial-grade backup systems for data centres, servers, and critical infrastructure. Their Smart-UPS line is specifically engineered for 24/7 uptime in enterprise environments, combining lithium-ion battery technology with intelligent power management to protect against surges, brownouts, and total power loss. A.P.C. systems include automatic voltage regulation (AVR), which stabilises fluctuating mains power without draining the battery—a feature that extends battery life and reduces maintenance costs. Their products are industry-standard in UK data centres because they prioritise redundancy and monitoring over low cost.
Top Picks
A.P.C. Smart-UPS 1500 LCD (SMT1500R2X122) — £1,091.19
Best for small-to-medium server rooms and workstation clusters. This 1500VA model delivers 1,000 watts of sustained output across 6 outlets, enough to keep 2–3 servers or a full workstation setup running for 10–15 minutes during an outage—sufficient time for a controlled shutdown or switchover to backup systems. The LCD display shows real-time battery status, load percentage, and estimated runtime in minutes, eliminating guesswork. Rack-mount design saves space in equipment cabinets.
A.P.C. Smart-UPS 2200VA Rack Mount 2U (SMT2200RMUS) — £1,749.99
Best for larger server installations and high-availability environments. This 2200VA system pushes 1,980 watts sustained output across 8 outlets, supporting heavier loads like multiple servers, network switches, and storage arrays simultaneously. The 2U rack form factor fits standard 19-inch cabinets without consuming excessive vertical space. Extended runtime batteries (available separately) can extend protection to 30+ minutes, making this the choice for mission-critical setups requiring longer failover windows.
Quick Comparison
| Model | Price | Best For | Standout Feature | |-------|-------|----------|------------------| | Smart-UPS 1500 LCD | £1,091.19 | Small servers, workstations | 6 outlets, 1000W output, compact | | Smart-UPS 2200VA RM 2U | £1,749.99 | Large server rooms, high availability | 8 outlets, 1980W output, enterprise-grade redundancy |
What to Look For
- Wattage vs. VA rating: The 1500VA model delivers 1,000 watts; the 2200VA delivers 1,980 watts. Match your server/device draw to the wattage, not the VA number—VA is apparent power, watts is actual usable power. Most modern servers draw 300–600 watts each.
- Outlet count and configuration: The 1500VA offers 6 outlets; the 2200VA provides 8. Ensure you have enough sockets for your servers plus network equipment (switches, firewalls). Battery-backed outlets are typically half the total—plan accordingly.
- Battery runtime: Both models deliver 10–15 minutes on battery at typical loads. If you need 30+ minutes, budget extra £400–800 for extended battery modules that slot into the UPS.
- Monitoring and alerts: Both include network management cards (optional add-on) that send email/SMS alerts if power fails, battery drains, or maintenance is needed. Critical for unattended data centres.
The Bottom Line
The A.P.C. Smart-UPS 1500 LCD at £1,091.19 is the logical choice for most small-to-medium UK installations—it covers typical server power draws, fits standard racks, and includes an LCD display for monitoring. Buy the 2200VA model at £1,749.99 only if you're running 4+ servers, storage arrays, or other high-power equipment; the extra £659 is worth it for environments where every minute of uptime translates to revenue protection.
Frequently Asked Questions
Is A.P.C. UPS actually reliable, or is it just hype?
A.P.C. is industry-standard in UK data centres and financial institutions—not because of marketing, but because their systems have genuinely low failure rates (mean time between failures of 100,000+ hours) and come with 3-year warranties plus optional extended support. If you need proof, check the specs: the Smart-UPS 1500 and 2200VA models are certified to UPS and safety standards (IEC 62040, EN 62040, UL 1391) and regularly tested in production environments.
How long will the battery last if power cuts out?
At typical loads, expect 10–15 minutes of runtime on the 1500VA or 2200VA models. The exact duration depends on how much load you're drawing—a lightly loaded server will run for 20+ minutes, while a fully loaded cabinet may drop to 5 minutes. A.P.C.'s online calculator lets you input your devices and watts to estimate runtime for your specific setup.
Can I connect these to my existing servers and get automatic shutdown?
Yes, if your servers support SNMP or USB UPS integration. Both the 1500VA and 2200VA models include USB and network management ports (sold separately on some models). Connect the USB cable to your server, install A.P.C.'s PowerChute software, and the server will automatically shut down gracefully when battery hits a preset threshold—preventing data corruption.
Do I need to replace the battery myself, or does A.P.C. do it?
Batteries are user-replaceable cartridges (RBC series) that slide out of the back—typically a 2-minute job. A.P.C. sells replacement batteries for £150–300 depending on capacity. Most data centres keep spares on hand. Battery life is typically 3–5 years, so budget for replacement every 3–4 years in continuous-duty environments.
