In an era where power reliability can make or break operations, having a robust uninterruptible power supply (UPS) is essential for businesses and individuals alike. The APC Smart-UPS C 1500VA LCD RM 2U 230V (SMC1500I-2U), designed by Schneider Electric’s renowned APC brand, is a standout option for those seeking efficient and affordable power protection. This rack-mountable UPS is tailored for entry-level servers, networking equipment, and other critical devices. In this blog, we’ll explore its features, benefits, and ideal applications to help you decide if it’s the right fit for your needs.
What is the APC Smart-UPS C 1500VA LCD RM 2U 230V (SMC1500I-2U)?
The SMC1500I-2U is a line-interactive UPS with a capacity of 1500VA (900 watts), designed to protect equipment from power outages, surges, and voltage fluctuations. Housed in a compact 2U rack-mountable form factor, it’s perfect for space-constrained environments like server rooms or IT closets. Operating at 230V, this model is optimized for regions with this standard voltage, delivering clean, reliable power to connected devices via its 4 IEC C13 outlets and 2 IEC jumper cables.
Unlike double-conversion UPS systems, the line-interactive design balances efficiency and protection by adjusting to minor power fluctuations without switching to battery power, reserving battery use for significant disruptions.
Key Features of the SMC1500I-2U
- Line-Interactive Topology with AVR
The UPS features Automatic Voltage Regulation (AVR), which corrects minor voltage dips and spikes without draining the battery. This ensures stable power delivery (180–287V input range) and extends battery life. - Pure Sine Wave Output
When running on battery, the SMC1500I-2U provides a pure sine wave output, mimicking utility power. This high-quality waveform is critical for compatibility with sensitive electronics and active power factor corrected (PFC) devices like modern servers. - Intuitive LCD Display
The front-panel LCD offers real-time data on load, battery status, input/output voltage, and estimated runtime. With easy navigation keys, users can configure settings and monitor performance at a glance. - Energy-Saving Green Mode
The optional Green Mode bypasses unused components during stable power conditions, achieving up to 97% efficiency. This reduces energy costs and heat output while maintaining protection. - Comprehensive Connectivity
Equipped with USB and serial ports, the UPS integrates with APC’s PowerChute Business Edition software for safe system shutdowns and detailed monitoring. It’s compatible with major operating systems, enhancing manageability. - Compact and Rack-Mountable
At 86mm high, 432mm wide, and 477mm deep, this 2U unit fits standard racks and includes mounting brackets for easy installation. Weighing 28.64 kg, it’s sturdy yet manageable. - Built-In Lead-Acid Battery
The internal battery provides approximately 10 minutes of runtime at full load (900W), with a recharge time of 3 hours. Replacement batteries (e.g., APCRBC132) are readily available for maintenance.
Benefits of the SMC1500I-2U
- Cost-Effective Protection: Ideal for small budgets, it offers essential features without the complexity or cost of higher-end models.
- High Compatibility: The pure sine wave output ensures seamless operation with a wide range of devices, from servers to networking gear.
- Reduced Downtime: With a 2ms transfer time to battery power, it prevents interruptions during outages, keeping critical systems online.
- User-Friendly Management: The LCD and software integration simplify monitoring and maintenance, even for non-experts.
- Eco-Friendly Operation: Green Mode lowers power consumption, aligning with sustainability goals.
Ideal Use Cases
The SMC1500I-2U is tailored for environments needing dependable yet straightforward power backup:
