The MPL Power Elektro RTS11-ON-3k0-2U-6x9 uses true Online double-conversion (VFI-SS-111 topology) to keep connected equipment completely isolated from mains power quality issues. Both mains and battery modes deliver pure sine wave output, so there is no waveform change when switching between modes and transfer time is 0 ms. The 19" 2U rack case accepts six hot-swappable 9 Ah/12 V AGM batteries that can be replaced on the front panel without powering down.

The high input power factor of 0.99 minimises reactive power draw, while the 0.9 output power factor provides 2700 W of active power from the 3000 VA rating. The charger restores 90% battery capacity in 3 hours. DSP processor control, ECO mode with efficiency above 97%, and UPSmart software communication (USB and RS-232 standard) round out the feature set.
