Double-Conversion UPS for Sensitive Equipment

The CyberPower OL3KRTHD is a 3000VA online UPS built for servers, lab instruments and other hardware that requires continuous sine-wave power. Its double-conversion topology regenerates output from the DC bus at all times, so connected devices never experience a transfer delay when utility conditions change.

Power Factor 0.9 Delivers 2700W Real Power

The unit’s 0.9 power factor means the 3000VA rating translates directly to 2700W of usable capacity, letting you load more active equipment per rack unit than lower-PF alternatives. Output voltage is user-configurable to 100, 110, 115, 120 or 125VAC within a tight +/-2% window.

Runtime Scales with Optional Battery Modules

Internal batteries provide 8.5 minutes at half load and 2.7 minutes at full load, recharging to 90% in four hours. For longer outages the chassis accepts up to ten BP48VL2U01 extended battery modules in a daisy-chain, while ECO mode pushes efficiency above 96% when utility power is clean.

Questions about this item

What does the 2700 W rating mean for the equipment I can connect?

The 2700 W rating is the maximum real power the UPS can supply continuously; your connected load must stay at or below this figure.

How does the NEMA L5-30P input plug limit where I can install the unit?

The NEMA L5-30P plug requires a matching 30 A, 125 V locking receptacle on a dedicated circuit.

What clearance and mounting hardware does the 2U rack form factor need?

The unit occupies 2U of rack height and includes brackets for standard four-post rack mounting.
