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.
