The APC Smart-UPS X SMX1500RMI2UNC is an uninterruptible power supply (UPS) in rackmount/tower design with an output capacity of 1.5 kVA and an output power of 1200 W. It provides power supply and protection for IT and network equipment against power outages, voltage fluctuations, overvoltages, and other grid disturbances. The UPS operates using line-interactive topology and delivers a pure sine wave output signal during battery operation, which is important for sensitive devices such as servers, switches, or storage systems. The nominal output voltage is 230 V, the input voltage ranges from 151 V to 302 V, and the frequency is 50/60 Hz. Automatic voltage regulation ensures stable power supply, even during minor grid fluctuations.

Applications

The UPS is suitable for use in small and medium-sized enterprises as well as in data centers where continuous power supply for IT infrastructure is required. It protects against short-term power outages and voltage sags that could lead to data loss or hardware damage. The combination of rack and tower operation enables flexible installation, whether in a 19-inch rack or as a freestanding unit.

Functions and Equipment in Detail

The front panel features an LCD display and LED indicators showing the operating status, battery charge level, and other parameters. The connections include eight C13 outlets, which are switchable in two groups via IEC jumpers, enabling targeted control of connected devices. An EPO (Emergency Power-Off) connection allows for safe shutdown in an emergency. The UPS supports cold start, meaning it can be activated even without mains power supply.

Technology Explained Simply

The UPS uses a sealed lead-acid battery (VRLA) with a capacity of 311 VAh. At full load, the typical backup time is 5.8 minutes; at half load, it is 17.2 minutes. The battery can be charged with temperature compensation, which extends its lifespan. Battery charging time is three hours. Battery life is up to five years, although environmental conditions such as temperature and power quality can influence lifespan. An automatic battery test regularly checks the battery condition.

Compatibility and Accessories

The UPS is equipped with a SmartSlot, into which a network management card (NMC) is installed, enabling remote monitoring and control via SNMP. The included network card supports the PowerChute Network Shutdown software, which enables controlled shutdown of servers and virtual machines in the event of a power failure. External battery packs (e.g., SMX48RMBP2U) can be connected to extend backup time. The UPS automatically detects external batteries.

Mounting and Installation

The device is designed for 2U rack mounting and can also be operated as a tower unit. The delivery includes the rack mounting kit, an RS-232 cable, a USB cable, a quick installation guide, and a software CD. Cable length is 1.83 m. Mounting is done using the included 4-post rack brackets or the feet for tower operation.

Advantages in Operation

The UPS achieves an efficiency of 98.5 % in online mode, resulting in low energy consumption and a low noise level of 40 dB. Integrated energy consumption measurement enables monitoring of power usage. The devices are intended for indoor use, with an operating temperature of 0 to 40 °C and relative humidity of 0 to 95 %. Maximum operating altitude is 3000 m. The UPS complies with standards CE, VDE, RoHS, REACH, PEP, and EOLI, as well as EN 50091-1 and EN 50091-2.
