You need more wattage than a basic line-interactive unit can give, but you don't want to burn three rack units doing it. The SRV2KRI-E slots into 2U and puts out 1800W of clean, double-conversion power. No transfer gap. No square wave. Just sine wave holding your gear up when the mains wobbles.
88% efficient at full load means less heat in a tight rack. Crest factor 3:1 handles those inrush spikes from drives and PSUs without tripping. Harmonic distortion sits at 3%, so your power factor stays honest on the meter.
Four IEC C13 outlets, IEC C14 input. The LCD shows you what's happening right now. The intelligent card slot takes an AP9544, SRVSMB001, or VGL9601l for network monitoring. Built-in auto and manual bypass means a UPS fault doesn't become a load outage.
The internal lead-acid battery is rated 3–5 years, recharges in about 4 hours, and the replacement cartridge (APCRBCV201) drops in when it's time. No pulling the whole unit out of the rack. Surge protection at 945J is built in. CE, UKCA, and TISI certified. If your computer room, small data centre, or clinic needs 1800W of on-line protection without the footprint of a 4U box, this is the one
