Tripp Lite's SVX30KM1P2B 30kVA/30kW SmartOnlineÂ® Medium-Frame UPS includes installed input, bypass and output breakers, a static transfer switch (STS) and 1 included 30kVA SVX30PM power module. This system supports the addition of up to 3 additional user-installable SVX30PM power modules to accommodate increased capacity up to 90kW with N+1 fault-tolerance. Two internal battery modules are included, with space for up to 3 additional SVXBM internal battery modules or any number of compatible Â±240VDC external battery packs (sold separately). Featuring a modular, scalable design with high-efficiency voltage and frequency independent/VFI operation, Tripp Lite's SVX Series SmartOnline UPS systems are ideal for the protection of a wide variety of critical IT systems. Scalable, modular configuration enables UPS capacity upgrades and hot-swap power supply maintenance without costly downtime. Over 95% efficient in standard online mode and over 99% efficient in optional economy mode enables reduced operating and cooling costs. Unity power factor configuration provides equal kVA and kW output ratings for up to 25% more wattage capacity than common 0.8 - 0.9 power factor competing designs. Network-grade sine-wave AC output with 1% output voltage regulation and less than 1.5% output total harmonic distortion. Advanced IGBT inverter with Digital Signal Processor (DSP) technology provides for less than 3% input total harmonic distortion (THDi) to support 1:1 generator sizing. Dual-input hardwire design enables operation from one or two input power sources for enhanced system availability.
