Frequently Asked Questions
What is the difference between a 5kW scalable UPS and a fixed 15kW UPS?
The APC Smart-UPS Modular Ultra starts at 5kW and scales to 15kW by adding modular power and battery components as your infrastructure grows. This approach reduces initial capital expenditure and allows you to pay only for the capacity you need, while maintaining the flexibility to expand without replacing the entire system.
Why choose Lithium-ion batteries over traditional lead-acid in a UPS?
Lithium-ion battery technology in the Smart-UPS Modular Ultra offers superior cycle life, faster charging, higher energy density, and reduced maintenance compared to lead-acid alternatives. This results in longer runtime per charge, extended battery lifespan (reducing replacement costs), and more reliable backup power for critical applications.
How does on-line UPS protection differ from standby UPS?
An on-line UPS like the Smart-UPS Modular Ultra continuously converts incoming AC power to DC and back to AC, providing zero-transfer-time protection with no switching delay. This ensures sensitive equipment receives clean, regulated power at all times, protecting against power surges, sags, and outages without any interruption.
Can I monitor and manage the UPS remotely?
Yes. The integrated network management card allows you to monitor UPS status, battery health, power events, and system alerts from any location via network connectivity. You can also configure automated responses and receive notifications for critical events, enabling proactive power management and faster incident response.
