Double-Conversion Online UPS

The CyberPower OL1KRM is a rack-mountable uninterruptible power supply that uses double-conversion online topology to deliver clean sine-wave output. It accepts 100 to 125 VAC input at 40 to 70 Hz and provides configurable output at 100, 110, 115, 120 or 125 VAC within two percent regulation. Eight NEMA 5-15R outlets supply up to 800 watts or 1000 VA from a single NEMA 5-15P input.

Suited For And Not Suited For

This unit suits network closets, server racks and workstations that require continuous voltage regulation and zero transfer time during power events. USB and serial ports enable management integration. Buyers needing longer battery runtime at full load or higher wattage capacity should consider larger models. Environments outside the zero to forty degree Celsius operating range or requiring non-standard outlet types are not a fit.

Capacity And Headroom

At full 800-watt load the internal sealed lead-acid batteries provide four minutes of runtime, extending to 11.5 minutes at half load. Recharge from empty to ninety percent takes four hours. Overload protection allows brief excursions to 130 percent for twelve seconds in line mode before bypass, and to 150 percent for two seconds before shutdown. Surge energy rating is 710 joules.

Questions about this item

What input plug does the OL1KRM need from my wall circuit?

The unit ships with a NEMA 5-15P input cord, so a standard 120 V 15 A receptacle is required.

Will my older 100 V equipment run safely on the configurable output?

Yes, the output can be set to 100 V ±2%, matching legacy 100 V gear while the UPS accepts 100–125 V input.

How do I confirm the double-conversion topology is active after installation?

Connect the USB or serial port and use the management software to verify the UPS reports Online mode with output voltage regulated to the selected 100/110/115/120/125 V setting.
