CyberPower adds 2.2 kW and 3 kW Online S UPS models for rack and tower deployments

Two higher-capacity Online S options

CyberPower Systems Oceania has announced two additions to its Online S uninterruptible power supply family: the OLS2K2ERT2UH and OLS3KERT2UH. The announcement was dated August 26, 2026, and positions the units for critical IT and connected-equipment installations where rack space, power quality and service continuity are material considerations.

The OLS2K2ERT2UH is rated at 2,200 VA and 2,200 W, while the OLS3KERT2UH is rated at 3,000 VA and 3,000 W. In each case, the equal VA and watt ratings indicate a 1.0 output power factor. That matters during sizing because the usable watt capacity is not reduced by a lower output power-factor rating; nevertheless, designers still need to calculate the actual steady-state load, inrush behavior and desired battery runtime.

Online double conversion for sensitive rack loads

Both products use online double-conversion topology and produce a pure sine-wave output. In this design, incoming utility power is converted and regenerated for the load rather than simply passed through under normal conditions. CyberPower lists zero transfer time for the models, a characteristic relevant to equipment that may be less tolerant of a changeover during an outage or major power disturbance.

For security and network racks, the likely protected loads include PoE switches, NVRs, servers, storage, access-control controllers, communications gateways and associated monitoring hardware. A UPS does not replace sound power-distribution, grounding, surge-protection and generator design, but it can provide ride-through time and a controlled opportunity for shutdown when the utility supply fails.

Serviceability and physical deployment features

CyberPower lists both models as rack/tower-convertible units and includes rackmount rails and ears with each system. Their 2U form factor makes them more directly applicable to four-post equipment racks than floor-standing UPS designs, although installers should account for equipment depth, rail compatibility, cable bend radius and the unit’s installed weight before finalizing rack placement.

A detachable maintenance-bypass PDU is included. The bypass arrangement is intended to let qualified personnel isolate or service the UPS while maintaining utility power to connected equipment. That can be useful in security environments where a planned battery or UPS service event should not take an entire camera, network or recording rack offline. Integrators should still document the bypass procedure, confirm the load and source conditions, and schedule maintenance in accordance with the manufacturer’s instructions and site operating requirements.

Monitoring, battery planning and outlet differences

The product pages list a tiltable color LCD, USB and RS-232 connectivity, relay-type dry contacts, an emergency-power-off port and optional SNMP/HTTP monitoring through CyberPower’s RMCARD205. These interfaces can support alarm integration, local power-management software and remote UPS status visibility, but the optional network-management hardware should be included explicitly in the bill of materials where remote supervision is required.

The 2.2 kW model is specified with six IEC C13 outlets and an estimated 12 minutes of runtime at half load. The 3 kW model has six IEC C13 outlets plus one IEC C19 outlet, with an estimated 9.5 minutes at half load. CyberPower also lists compatible extended battery modules and hot-swappable, qualified-personnel battery replacement. Published runtimes are estimates made with new, fully charged batteries, so a project design should model the actual load and apply allowance for battery aging, temperature and runtime objectives.

Important regional check for U.S. specifications

These exact SKUs appear on CyberPower’s Australia site and are described with a 230 V nominal input, IEC C20 input connection, Australian detachable power cord and CE/RCM certifications. Although their listed output-voltage options include 208 V, the available documentation does not establish that these are U.S.-market models or that they carry the approvals required for a particular U.S. installation.

Accordingly, U.S. procurement teams should not treat the OLS2K2ERT2UH or OLS3KERT2UH as automatic substitutes for a North American 120 V rack UPS. Before ordering, confirm branch-circuit voltage, plug and receptacle arrangement, output distribution, local code and listing requirements, distributor availability, service support and warranty terms. The announcement is a useful indicator of CyberPower’s current Online S platform direction, but final selection should use the regional SKU and documentation applicable to the project site.
