It delivers full rated power at unity power factor (kVA = kW) with efficiency of up to 96.5%, and a compact cabinet that suits small data centres, server rooms, network infrastructure, building systems, and other mission-critical loads. A 5-inch colour touchscreen, USB, RS232, and RJ10 ports, communication card slots, and parallel capability for up to 8 units make it easy to monitor, expand, and build redundancy.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eONLINE DOUBLE CONVERSION: CLEAN, REGULATED POWER ALL THE TIME\u003c\/p\u003e\n\u003cp\u003eIn online double-conversion mode the UPS rebuilds the output power continuously, so connected equipment always runs on clean, regulated power with no transfer time when the mains fails, drops, or surges. Servers, storage, network equipment, and industrial controls stay isolated from brownouts, spikes, and noise on the utility supply.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e40KVA = 40KW: UNITY POWER FACTOR\u003c\/p\u003e\n\u003cp\u003eThe S3T 40 delivers its full 40kW of real power at unity power factor, so a 40kVA rating means 40kW of usable load. Many UPS systems at this size give up 10% or more of their rating to a lower power factor, so unity PF lets you size for the load you actually have.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eTRANSFORMERLESS, THREE-PHASE (S3T)\u003c\/p\u003e\n\u003cp\u003eThe S3T version has three-phase input and three-phase output. The transformerless design is compact and light for its capacity, and Riello builds on its Multi Sentry (MST) series with an optimised card layout that reduces components, cables, and interconnections, which saves installation space and eases maintenance. Optional isolation transformers are available.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eUP TO 96.5% EFFICIENCY\u003c\/p\u003e\n\u003cp\u003eEfficiency reaches up to 96.5% in online double-conversion mode, with high efficiency maintained from loads as low as 50%.
