1500VA 1200W Online UPS

The CyberPower OL1K5RM is a rackmount uninterruptible power supply with double-conversion topology and sine-wave output. It accepts 100 to 125 V input and provides configurable output at 100, 110, 115, 120 or 125 VAC within two percent. Eight NEMA 5-15R outlets support critical servers, network gear and lab equipment requiring zero transfer time to battery.

Replaces line-interactive units

Double conversion removes the switchover delay found in line-interactive designs, protecting sensitive loads from every fluctuation. The upgrade is worth it when equipment cannot tolerate even a brief break or distorted waveform. Generator compatibility and an input frequency window of 40 to 70 Hz add flexibility for unstable utility or backup generator sources.

4.7 minutes at full load

Three 7 Ah sealed lead-acid batteries deliver 4.7 minutes runtime at 1200 W and 13.5 minutes at half load. Recharge to ninety percent takes four hours. The replaceable RB1270X3B cartridge and optional Extended Battery Modules let you scale runtime for longer outages. USB and serial ports enable monitoring and automated shutdown scripts.

Questions about this item

How deep is the rack space needed for this 2U unit?

The OL1K5RM occupies a standard 2U rack height; allow at least 40 cm of usable depth behind the front rails for the chassis, cables and airflow.

Which cable must be connected first when installing the UPS so the batteries activate?

Plug the NEMA 5-15P input cord into a 100-125 V branch circuit, then press the front-panel power button; skipping the mains connection leaves the unit on battery only and it will shut down after 4.7 minutes at full load.

What is the exact replacement battery kit for the three internal 7 Ah cells?

Order the RB1270X3B kit; it contains three matched 12 V 7 Ah sealed lead-acid blocks that restore the original 4.7-minute full-load runtime after a four-hour recharge to 90 percent.
