The SMC3000I is a tower-configured UPS designed for easy setup and maintenance, offering a compact yet powerful solution for protecting critical electronics.

Key Features

1. Line-Interactive Topology with AVR

The SMC3000I features line-interactive technology with Automatic Voltage Regulation (AVR), which corrects low and high voltage conditions without relying on the battery. This extends battery life and ensures higher availability, especially in areas with unstable power grids. The pure sine wave output provides clean power, making it compatible with sensitive equipment like servers and power-factor-corrected (PFC) power supplies.

2. Robust Power Capacity

With a 3000VA/2100W capacity, the SMC3000I can support multiple devices, such as servers, networking equipment, and workstations. It includes:

  • 8x IEC C13 outlets and 1x IEC C19 outlet, all with battery backup and surge protection.
  • IEC-320 C20 input for compatibility with standard power setups.

This capacity makes it suitable for small server rooms, retail environments, or offices with critical equipment.

3. Intuitive LCD Display

The multifunction LCD interface provides real-time status updates, including input/output voltage, load capacity, battery level, and estimated runtime. The display is user-friendly, with multiple status indicators and bar graphs for load and battery levels, allowing easy monitoring and configuration without additional software.

4. High-Efficiency Green Mode

The SMC3000I operates in a patent-pending Green Mode, bypassing unused electrical components during stable power conditions to achieve high efficiency (up to 97–98%). This reduces utility costs and heat generation, making it an eco-friendly choice for businesses aiming to lower their energy footprint.

5. Advanced Battery Management

The UPS uses a maintenance-free sealed lead-acid battery (replaceable with APC RBC7 cartridge) with a typical lifespan of 3–5 years. Features include:

  • Temperature-compensated charging to prolong battery life.
  • Automatic self-tests to ensure battery reliability.
  • User-replaceable battery for easy maintenance without powering down connected devices.

A low battery alarm provides timely notifications for replacement, and the battery can be disconnected for transport (tower models).

6. Comprehensive Power Protection

The SMC3000I offers network-grade power conditioning, including:

  • AVR to stabilize voltage fluctuations.
  • Surge protection against lightning strikes, sags, and surges.
  • Noise filtering (0.7% IEEE surge let-through) to protect sensitive electronics.

These features ensure optimal performance and longevity for connected devices.

7. Management and Connectivity

The UPS includes USB and RS-232 ports for local management and supports PowerChute Business Edition software for safe system shutdowns and monitoring. While the SMC3000I does not include SmartConnect (cloud-based monitoring, available in SMT3000IC), it is compatible with an optional Network Management Card (AP9630) for remote monitoring via web or network management software.

8. Cold-Start Capability

The SMC3000I can provide temporary battery power during outages even without utility power, thanks to its cold-start capability. This is useful for emergency scenarios or powering devices in remote locations.

Performance

The SMC3000I delivers dependable performance for critical applications:

  • Backup Time: Provides ~5.8 minutes at full load (2100W) and ~16 minutes at half load (1050W), sufficient for safe shutdowns or bridging short outages.
  • Transfer Time: A typical transfer time of 6ms (maximum 10ms) ensures seamless switching to battery power, minimizing disruption to sensitive equipment.
  • Power Quality: The pure sine wave output ensures compatibility with modern IT equipment, preventing issues with PFC power supplies.

User feedback highlights stable performance during power fluctuations, with the AVR effectively handling voltage sags and surges without battery activation. The UPS is noted for its quiet operation compared to higher-capacity models like the SMT3000I, though some fan noise may be audible under heavy loads.

Pros and Cons

Pros

  • Cost-Effective: Lower price point (~$900–$1,200) than premium models like the SMT3000I, offering excellent value for 3000VA capacity.
  • Pure Sine Wave Output: Ensures compatibility with sensitive electronics.
