The APC SUA3000I is a 3000VA/2700W uninterruptible power supply (UPS) designed to protect critical equipment from power disruptions. With features like pure sine wave output, scalable runtime via external battery packs, and intelligent battery management, it ensures seamless power backup for servers, network hardware, and enterprise systems. Its hot-swappable batteries and LCD interface enhance usability and reliability.

How Does the APC SUA3000I Protect Critical Equipment?

The SUA3000I uses automatic voltage regulation (AVR) to correct minor power fluctuations without switching to battery mode. During outages, it delivers pure sine wave output, preventing data loss or hardware damage. Its zero-transfer time ensures uninterrupted power, making it ideal for sensitive electronics like servers and medical devices.

Advanced surge protection circuits defend against voltage spikes up to 6000A, while EMI/RFI filtering eliminates line noise interference. The UPS employs a three-stage charging system that optimizes battery life – bulk charging for rapid recovery, absorption charging for voltage stabilization, and float charging for maintenance. For environments with frequent brownouts, the SUA3000I’s adaptive voltage threshold automatically adjusts sensitivity based on local power conditions. This prevents unnecessary battery cycling while maintaining protection during sustained undervoltage events.

What Maintenance Does the APC SUA3000I Require?

Replace batteries every 3-5 years. The LCD panel displays battery health, and PowerChute software sends alerts for low capacity. Keep vents clean and operate in environments below 104°F (40°C). Test the system quarterly using the self-diagnostic feature.

Implement a proactive maintenance schedule using the included PowerChute Business Edition software, which tracks battery cycles and predicts replacement needs. For high-availability installations, consider implementing redundant UPS units in parallel configuration. The battery compartment’s front-access design enables replacements without powering down connected equipment. Use APC’s Battery Frame (AP9630) for external packs to maintain proper airflow and simplify monitoring. Always dispose of lead-acid batteries through certified recycling programs to meet environmental regulations.

Which Industries Benefit Most from the APC SUA3000I?

Data centers, healthcare facilities, and telecom networks rely on the SUA3000I for stable power. Its scalability suits environments requiring extended runtime, while industrial settings appreciate its rugged design and compatibility with generator power.

How to Extend the APC SUA3000I’s Battery Runtime?

Connect up to two APC Smart-UPS External Battery Pack (SMX72BP) units. Each pack adds 7Ah capacity, extending runtime by 50-200% depending on load. The UPS automatically detects added packs and adjusts runtime calculations via PowerChute software.

Can the APC SUA3000I Integrate with Smart Energy Systems?

Yes. The SUA3000I supports Schneider Electric’s EcoStruxure platform, enabling real-time energy monitoring and integration with renewable energy sources. Its Modbus TCP/IP protocol allows compatibility with building management systems for optimized power distribution.

“The SUA3000I’s modular design and pure sine wave output set it apart in mid-range UPS systems. Its ability to scale runtime without downtime makes it a cost-effective choice for growing enterprises. However, users should prioritize firmware updates to mitigate cybersecurity risks in networked environments.” — Data Center Power Solutions Expert

FAQ

Does the APC SUA3000I support lithium-ion batteries?

No, it uses lead-acid batteries. Third-party Li-ion conversions void the warranty and risk thermal runaway.

Is the APC SUA3000I compatible with solar power systems?

Yes, when paired with a hybrid inverter. The UPS stabilizes output during grid-solar transitions but doesn’t directly store solar energy.

How loud is the APC SUA3000I during operation?

It operates at 45dB in normal mode and 55dB during battery use—quieter than most rack-mounted UPS systems but unsuitable for noise-sensitive environments.
