What is the APC Smart-UPS C 3000VA Rack Mount LCD 230V (SMT3000RM12U)?
The APC Smart-UPS C 3000VA (SMT3000RM12U) is a line-interactive UPS offering a power capacity of 3000VA (volt-amperes) or 2700 watts. Designed for 230V regions—common in Europe, Asia, and Africa—this 2U rack-mountable unit provides efficient, network-grade power protection. It’s part of APC’s Smart-UPS C series, known for balancing performance and affordability while catering to entry-level and scalable runtime needs.
This UPS uses line-interactive technology, which allows it to correct voltage fluctuations without always switching to battery power, enhancing efficiency and battery longevity. With its LCD display and smart features, it’s a reliable solution for businesses needing to safeguard critical infrastructure in a compact, rack-optimized form factor.
Key Features of the APC Smart-UPS C 3000VA (SMT3000RM12U)
Here’s what makes the SMT3000RM12U a standout in its class:
1. Power Capacity and Output
- 3000VA / 2700W: With a robust 2700-watt output, this UPS can support high-power devices like servers, storage systems, and networking gear. At half load (1350W), it offers around 11-12 minutes of runtime, while at full load (2700W), it provides approximately 4-5 minutes—sufficient for safe shutdowns or bridging brief outages.
- Pure Sine Wave Output: Unlike basic UPS models, it delivers a clean, pure sine wave on battery power, ensuring compatibility with sensitive electronics and active power factor correction (PFC) equipment.
2. Line-Interactive Technology with AVR
- The Automatic Voltage Regulation (AVR) adjusts low and high voltages without relying on the battery, making it ideal for areas with unstable power. This feature boosts efficiency and protects connected devices from brownouts and surges.
3. Connectivity and Management
- Outlets: It features 8x IEC C13 and 1x IEC C19 outlets, providing versatile connectivity for multiple devices, plus a C20 input for power supply.
- LCD Display: The intuitive LCD interface offers real-time status updates, including load levels, battery health, and runtime estimates, simplifying monitoring and control.
- SmartSlot and Ports: Includes a SmartSlot for optional network management cards, plus USB and serial ports for integration with APC’s PowerChute software, enabling remote monitoring and automated shutdowns.
4. Battery and Efficiency
- Hot-Swappable Battery: The sealed lead-acid battery is user-replaceable and can be swapped without powering down connected equipment, minimizing downtime.
- Green Mode: A patented high-efficiency mode bypasses unused components during stable power conditions, achieving up to 97% efficiency and reducing energy costs.
5. Design and Build
- 2U Rack-Mountable: Its compact 2U form factor fits standard server racks, making it perfect for data centers or IT closets with limited space.
- Cold-Start Capability: Can power devices briefly without utility power, a lifesaver during unexpected outages.
Benefits of the APC Smart-UPS C 3000VA (SMT3000RM12U)
