APC SRV3KI-E uninterruptible power supply (UPS) Double-conversion (Online) 2700 W

The APC SRV3KI-E 2700 W Double-conversion uninterruptible power supply provides continuous, regulated power for critical equipment. This online UPS delivers 2700 W output power with a true sine wave output and is built with C13 and C19 outlets to support a variety of server and network devices. The unit uses a 72 V sealed lead acid battery system and features an LCD display that shows status and load information. With a compact footprint (190 mm width, 425 mm depth, 336 mm height) and a weight of 26 kg, it is intended for installations where reliable, high-quality backup power and voltage regulation are required.

Advantages

The double-conversion design continuously conditions incoming power, isolating connected equipment from mains disturbances and providing stable, clean sine wave output regardless of input fluctuations. The included LCD enables clear monitoring of operating parameters such as load, battery status and input/output conditions. The combination of C13 and C19 outlets offers flexibility for mixed rack and tower equipment, while the sealed lead acid battery and four-hour recharge time provide predictable recovery after discharge.

Suitable for

• Small to medium server racks and network switches
• Critical IT infrastructure such as storage controllers and virtualization hosts
• Telecommunications equipment and VoIP systems
• Workstations and point-of-sale terminals requiring clean power

How to use

Install the UPS on a stable, ventilated surface or in a compatible rack shelf following the manufacturer's mounting guidance. Connect the UPS to a correctly rated mains supply and use the LCD to verify input voltage, load level and battery condition before connecting critical equipment. Plug devices into appropriate C13 or C19 outlets, ensuring the total connected load does not exceed the rated 2700 W output. In the event of mains failure, the UPS will transfer to battery-derived power immediately and continue to supply a true sine wave output until mains is restored or the battery is depleted. After a discharge event, allow the UPS to recharge the battery for the recommended recharge interval.

Recommendations

For reliable operation, regularly inspect battery status via the LCD, schedule periodic maintenance and perform battery replacement according to runtime needs and battery health. Ensure adequate ventilation around the unit, avoid placing it in direct sunlight or near heat sources, and plan connected load to allow graceful shutdown of critical systems if runtime is limited.
