The APC Smart-UPS X 1500VA (manufacturer's number 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 systems, servers, network equipment, and other sensitive devices against voltage fluctuations, power outages, and other grid disturbances. The device is designed for use in server rooms, data centers, and other IT environments where continuous and stable power supply is required.

Applications

The UPS is suitable for use in IT infrastructures, particularly for servers, network devices, and storage systems. The 2U rack format enables flexible installation in standard 19-inch racks, with the option for tower operation also available. The nominal input and output voltage is 120 V, indicating use in regions with 120-V mains voltage. The input frequency of 50/60 Hz makes the device compatible with various power grids.

Functions and Equipment in Detail

The device features eight AC outlets with the NEMA 5–15R plug type, designed for powering IT devices. The battery/accumulator technology is based on sealed lead-acid (VRLA), using the RBC115 battery type. The battery recharge time is 3 hours, enabling rapid restoration of backup power capacity. The UPS is equipped with LED indicators that visually display the operating status, and includes acoustic signals for notifications of operating conditions or faults. The noise level is 40 dB, ensuring quiet operation in offices or server rooms.

Technology Explained Simply

The UPS operates in line-interactive mode, where the battery is activated only in the event of a power failure. In normal operation, the load is supplied directly from the mains, with voltage fluctuations regulated by the UPS. The output voltage is pure sine wave during battery operation, which is important for sensitive IT devices. The energy surge capacity is 600 J, describing the ability to absorb power surges and transients. The SmartSlot and USB interfaces enable integration into network management systems and remote monitoring of the device.

Compatibility and Accessories

The device is compatible with external battery modules that enable extended runtime. Suitable accessories include the Ext. Battery Module Smart-UPS 48V X-Series 2HE Rack/Tower, which can extend the runtime. The UPS supports automatic detection of external batteries, simplifying installation and scaling. Scalability of runtime is a key advantage for users requiring individual runtime adjustments.

Mounting and Installation

The UPS is designed as a rackmount/tower model and occupies 2U in a 19-inch rack. The cable length is 2.44 m, allowing flexible placement. Mounting is done using integrated rails, with tower operation also supported. The device color is black, fitting typical server environments.

Operational Advantages

The UPS offers a high online efficiency, minimizing energy consumption and reducing operating costs. The integrated energy consumption measurement enables monitoring of power usage. The display of the battery replacement deadline supports maintenance and prevents unexpected failures. Support for cold start and temperature compensation during battery charging increases reliability under variable conditions. The EPO function (Energy Power-Off) enables orderly shutdown of systems in emergencies.

Operating Conditions

The device can be operated at temperatures from 0 to 40 °C and relative humidity from 0 to 95 %. Storage is possible at temperatures from -15 to 45 °C and humidity from 0 to 95 %. The maximum operating altitude is 3000 m, and the storage altitude is 15000 m. Certification is according to cUL and UL 1778, and RoHS compliance is given. The warranty is 3 years for electronics and 2 years for the battery.
