BRAVO Inverter, 2500VA Inverter (-48Vdc + 230Vac) / 230Vac Features and Benefits Dual input sources (AC & DC) Compact and lightweight solution High efficiency Full scalability and expandability Hot swappable Pure sine wave on AC output Transfer time reduced to naught No single point of failure Total modularity as no external static-switch required DC Power for Business-Critical Continuity ™ Description Inverter systems are normally used for AC backup requirements in a telecom / datacom site or anywhere a highly reliable AC power back up source is needed. BRAVO is a compact and scalable inverter providing a pure sine wave AC supply. In conjunction with a DC Power system, it provides an excellent AC backup solution. The TSI (Twin Sine Inverter) uses the latest inverter technology, providing superior energy efficiency in a compact size. The inverter is designed to work from 230Vac and 48Vdc sources through AC/AC and DC/AC conversions. Unlike traditional inverters, the TSI features an AC to AC conversion that assures double filtering function. This results in an efficiency of 96% without any compromise in quality and stability of the output wave form. This off line operation mode is called “Enhanced Power Conversion” (EPC). The EPC mode, which is the filtering of current and voltage, is similar to a rectifier combined with an inverter (online mode) but gives a significantly better efficiency. Compared to a UPS operating in offline mode (no current conversions) the efficiency is the same, but the rejection of grid disturbances is much higher. The online mode is usually only used during a mains outage when inverters are fed by batteries. Therefore, the TSI inverters will almost constantly provide an efficiency of 96%. It will always be the most reliable AC backup solution! The TSI inverters also have an in-built static switch function. Because no external static switch is needed, the inverter system becomes smaller, more reliable and easily expandable. As many as 32 inverter modules can be used in parallel.
